The objective of the device is to shut off and adjust the flow characteristics of the liquid or gas, and thus quickly eliminate the emergency.
Electrically operated shut-off valves are actively used in the gas industry, utilities, agricultural enterprises and in the oil refining industry.
Benefits of Electric Valves
There are many advantages of such fittings. These include:
- reliability;
- simplicity of design;
- uninterrupted operation guarantee;
- long operating time;
- small dimensions of the valve;
- high power;
- high speed of opening the flow of the working medium, or vice versa, its overlap;
- withstand even significant, sharp pressure drops;
- have a safety function and a wide range of operating temperatures;
- economical power consumption;
- the ability to perform the necessary work with the valve remotely (using the control panel).
The device is an energy-saving equipment, since it is possible to switch to two degrees of power. In addition, such mechanisms absolutely comply with all standards for precise regulation of water temperature, and are used to supply the working medium to heating systems.
Design and operation features of the electric valve
An electrically actuated valve for water provides the optimum pressure of the working medium in any technological system or in a specific section of the pipeline. The valve has the following equipment:
- Actuator in the form of an electric drive.
- Regulating valve (acting on a liquid or a mass of gas.
All parts of the device are functionally dependent on each other. Despite the simplicity of the design, the valve can perform continuous monitoring of fluid characteristics and timely prevent an emergency by activating locking equipment in a split second. All this reliably protects the pipeline system from water hammer, and does not allow the return passage of the working medium.
Attention: when installing the adjusting mechanism, it is important that the direction of the mass of the working medium matches the arrows shown on the valve body.
When mounting the adjusting mechanism, it is necessary to trace the direction of the mass of water or gas in the direction of the arrows that are shown on the housing.
With this article, we begin a series of materials devoted to individual elements of automation systems. In the first article we will get acquainted with the purpose, structure and principle of operation of solenoid valves with electric actuators.
Valves are devices that regulate: pressure, temperature, direction of flow of liquid or gas in a pipeline.
All valves can be divided into unregulated and adjustable, in which the geometric dimensions of the working windows or their number depend not only on the parameters of the fluid flow, but also on external influences.Valves can be distinguished: overflow, pressure reducing, safety, return and switching.
An adjustable valve is a valve that changes the flow of liquid (gas) that enters or is diverted from an object of regulation.
An adjustable valve is a variable hydraulic resistance with a variable flow area from zero (when the plunger fits into the seat) to a maximum (with the valve fully open) and with a variable coefficient of local resistance, because the flow rate varies in magnitude and direction.Most often, an adjustable valve is articulated by actuators and usually constitutes a common unit with them.
Motorized valves are one of the most popular types of pipeline equipment. With their help, you can block and adjust the characteristics of the flow of liquid or gas, eliminate the emergency. They are widely used in utilities, gas and oil industries, and in agriculture.
The advantages of these devices include: high speed of opening the stream or its overlap, reliability and durability in operation. The electric drive provides the ability to work with valves remotely from the control panel.
The mechanisms comply with high standards for precise regulation of the temperature of hot water for supplying it to the heating system. The material of the valve, which works with an electric actuator, can withstand large pressure drops. Electric drives are made with a safety function.
Pressure regulator - a control valve, with an electric actuator monitors the pressure of the working medium in the pipeline section or in the technological system. Such a device consists of functionally dependent parts: a distributing effect on the regulatory part and a control valve that acts on the mass of gas or liquid.
The executive mechanism of such a system is. The main purpose of regulatory mechanisms is to manage manufacturing processes. The device allows it to continuously monitor the characteristics of the working medium (pressure, flow rate of water or gas, temperature ...), and also prevents emergency situations, instantly turning on locking equipment, protects the lines from water hammer, and prevents the return passage of working media.
When mounting the adjusting mechanism, it is necessary to trace the direction of the mass of water or gas in the direction of the arrows that are shown on the housing.
The pipelines on which the control valve is installed must be evenly laid and securely fixed, and also protected from vibration. The device can be mounted both vertically and horizontally, but the drive must always be located on top. Be sure to leave space for dismantling or mounting the drive.
Three way mechanism
A three-way valve with an electric actuator does not carry out a change in the direction of movement of the mass of liquid, its pressure is constant, only the proportions of the passage of cold and hot water change. The design of the device is such that both cold and hot liquids are suitable for it, and a mixture of the desired temperature is obtained at the outlet.
A fairly simple design of the part is a housing in which there are two inlets and one outlet. The regulating element is either a rod of a certain design, which can move in the vertical direction, or a ball rotating around a fixed axis. The working element does not completely block the mechanism, but only directs the flow of gas or water so that they mix.
The drive system, receiving commands from the sensors, allows you to change the temperature of the fluid in automatic mode. The most accurate adjustment was received by a three-way part with an electric drive, therefore it is most widely used.
The electric drive that comes with the device can be either a servo drive. A solenoid is a core coil through which an electric current flows, i.e. electromagnet. A servo drive is a device in which an input electrical signal controls mechanical movement with a compact electric motor.
The materials from which this equipment is made include cast iron, steel and brass. Steel and cast-iron devices are installed in the main with a large passage of water or gas. Small parts are made from brass.
Three-way devices are in demand products, since there are simply no analogues that could replace them. Only this equipment can ensure that the temperature of the working medium is maintained at the proper level. Well-developed technology for the execution of three-way mechanisms. The nomenclature of this product is such that the product will satisfy any request.
Sophisticated technical device and the price is considerable, but it provides reliability and durability during operation.
Locking mechanism
Electric shut-off valve - This is a locking valve made in the form of a valve. The element that blocks the flow of water or gas moves parallel to the axis of this stream. Such devices are used to completely block the flow section. Such a locking element is a spool, which can only be in the “open” or “closed” positions during operation.
They also make shut-off - regulating equipment, which has the additional function of regulating the flow rate of the passing fluid.
Until 1982, valves of this type were called valves, but the Guests abolished this name.
These devices are widely used as locking valves because of reliable sealing with a spool and structural simplicity of execution. They are used for gaseous and liquid media with a wide range of operating characteristics: temperatures from -200 ° C to +600 ° C; pressure from 0.7 Pa to 250 MPa.
Equipment of this type is installed on highways with a small diameter, otherwise it will take a lot of effort or a complicated design to properly install the shutter in the housing. A new modification of the locking device, which has a worm gear housed in a housing with a cover, an electric drive, input and output flanges, a stationary sealed seat and a movable shutter.
The mechanism of the indicator of the location of the shutter is a housing with a movable sleeve, on which an internal thread is applied. The rotation stop and the scale located outside indicate in which position the shutter is. The shutter location indicator mechanism is mounted on the shaft of the worm.
One revolution of the worm corresponds to a pointer movement of 1 mm. The result was an increase in the accuracy of the measurement of the shutter position. In addition, this valve design has reduced the effort to move the shutter.
If a locking mechanism is used at some site, then multi-turn electric drives are used to control it. The shut-off valve with an electric actuator closes and opens the piping system, while changing the pressure in the system, they change the direction of fluid flow in the pipeline.
Advantages of a shut-off valve with an electric actuator:
- the possibility of slow closing or opening of the pipeline, as a result of which the force of the "hydraulic" shock is reduced;
- simple design allows you to simplify equipment maintenance;
- wide range of operating temperatures and pressures;
- small dimensions of devices.
The element has great power and high reliability in operation. The device relates to energy-saving equipment, as it has the ability to switch to two degrees of power, which allows you to save electricity.

Electric actuators for air valves and air spring dampers
Air valve actuators with spring return are designed to automate the control process of the damper and simultaneously perform security functions (protection against smoke or freezing) in general ventilation and air conditioning systems.
And the dampers are devices for regulating the flow in ventilation, heating and air conditioning systems. The scope of their application affects various spheres of human activity - from household appliances to industrial fire safety systems. The functioning of these elements is provided by drives, the most effective of which are electrical.
Varieties of electric drives
Different types of valves require a variety of designs used in their composition of elements. Regulating actuators for valves are classified by the following characteristics:
- Principle of operation. According to this indicator, two types of devices are distinguished - thermoelectric and gear. The former are more common in domestic ventilation systems, in their work the main role is played by heating an electric spiral, which provokes an increase in the temperature of the working substance of the bellows. The expansion of the substance creates pressure, under the action of which the valve stem moves. Gear drives operate due to gear transmission, which provides transmission of force from the motor to the valve.
- The magnitude of the voltage. It is selected depending on the mains in which the device will operate. For the on-board system of the vehicle - 24V, for a stationary network - 220V.
- Working effort. This indicator varies in the range from 90N to 5000N, depending on the modification of the device.
vSpeed. Depending on the value of this parameter, fast (3-4 seconds) and slow (8-15 seconds) drives are distinguished. - Type of attachment to the valve. The configuration of the actuator corresponds to a certain type of valve, the connection is made using clamps and nuts, the size of which must be selected according to the existing valve.
- Complete with protective devices. To ensure valve actuation in an extreme situation (power outage), a return spring is used, the energy reserve in which allows the damper to return to its protective position even when the power supply is cut off. Models not equipped with such springs, in the absence of electricity, can only be operated manually.
- Destination. On this basis, electric drives for fire dampers and electric drives for smoke exhaust valves are distinguished. The first are equipped with a return spring and are made in a fireproof housing, since their use in emergency situations is implied. Such devices are necessary to prevent the spread of smoke and fire through the ventilation system and in case of fire will play an important role in preserving the lives and health of people.

Hello dear reader! In industrial pipelines through which a huge flow of liquids is continuously moving, it is necessary to regulate this movement, reducing or increasing the flow rate, the pressure in the pipes. In such cases, plays an indispensable role. In our article, we will consider its types and characteristics, connection methods, rules of use, get acquainted with the advice of specialists on the installation and operation of the unit.
The shut-off valve with various types of actuators is a device with which you can completely or partially block the moving fluid flow in the pipeline.
A design feature with an electric drive is that it allows you to perform these actions remotely, almost anywhere on the highway.
Appointment and scope
Regulating valves allow you to automatically control from a distance the process of regulating fluid flow, pressure forces in pipelines.
They are used in large trunk, technological and communal network channels through which the medium is transported.
They can be both shut-off, with the function of only completely blocking the pipe, and with the function of regulating the flow force by completely or partially suspending it.
Management and specifications
The valve is controlled by linear movement of the stem with the plunger. The device is started by pressing the start button on the remote control. Under the influence of electric current, the drive transfers force to the plunger. That, moving up and down, changes the cross-sectional area of \u200b\u200bthe through hole.
The main technical characteristics of stop valves are:
- the value of the nominal pressure in the system that the device can withstand;
- nominal diameter in mm;
- conditional throughput in m3 / h;
- limits of temperature values \u200b\u200bat which the unit functions normally;
- mains voltage intended for electric drive.
Type of connection
According to the type of connection, shut-off and control devices are divided into
- flanged
- nipple
- coupling
- hoe,
- welded.
As a rule, valves of this type are already equipped with flanges. They are used in high pressure networks. Through the flange, the unit can be attached to any pipes suitable for the size of the conditional passage. It also does not depend on what type of device will be connected.
Device
The simplest control valve consists of a housing with flanges in which a seat is located, a stem with a plunger at the end and a sealing assembly responsible for sealing the entire stop valve.
When the plunger closes only part of the passage opening, the flow rate of the system decreases. The plunger tightly lowered into the saddle shuts off the flow, the pressure in the pipe after the fittings drops to zero.
If ball valves are used in domestic pipelines, in industrial highways and utility networks, spools and valves with an electric motor are preferred.
Principle of operation
The principle of operation of the electric valve is much similar to the operation of a conventional valve. They are distinguished by their control method and functionality.
By the principle of action, blocking, mixing or dividing the main flow devices are isolated.
The overlapping units include two-way valve valves, widely used in public heating networks.
For mixing and separation of the flow, having three nozzles for connection to the highway.
Types and differences of designs
Valves for the drive device are divided into controlled:
- manually;
- electric drives;
- pneumatic drives;
- electromagnetic way.
According to the locking mechanism, the structures are divided into:
- locking, designed only for the closure of the medium;
- membrane, with a rubber membrane in the housing, adapted to work in gas networks;
- reverse, closing when the direction of flow changes;
- spool, regulating the flow rate due to the movement of the movable spool;
- saddle, with linear movement of the stem with a plunger, closing or opening the way for flow with the help of saddles.
Advantages and disadvantages
The advantages of a pneumatic drive are its affordable price, devices with such controls are cheaper than electrical counterparts.
Valves with an electromagnetic actuator greatly facilitate the process of remote control of the medium over a long section of the highway, and allow the introduction of an electronic control system.
The device itself will be able to take accurate indicators of the state of the same coolant in the pipelines, transmit information to the operator about the level of pressure, the amount of fluid in the stream, and even reset the positions of the shut-off parts of the structure.
However, the price and complexity of the devices will increase.
The optimal choice of device should provide high accuracy in regulation. Many factors must be considered in order to make the right decision to purchase a machine.
When selecting fittings, pay attention to:
- product marking, which indicates the throughput and nominal pressure for the device;
- conditions for the maintenance of the device, whether it is possible to repair it without removing it from the line;
- is it possible to change the bandwidth of the device;
- the presence of structural elements in the device that reduce the amount of noise.
Rules for installation and operation of the device
Before installing the device, check the fasteners, the inner part of the valve and pipes of the highway for the detection and removal of foreign particles. If the need arose, the appliance is washed and purged.
After installation, check the device for operability.
During operation it is necessary to periodically, at least twice a year, inspect the device and carry out routine maintenance.
Check the general condition of the device and its fasteners.
All work with the electrovalve must be carried out in accordance with the instructions attached to it.
Necessary tools and materials
You will need the following set of tools:
a screwdriver with appropriate nozzles;
- screwdriver;
- pliers;
- flushing hose.
Materials:
- set of bolts;
- copper tubes for wires;
- electrical wire.
Wiring diagram
Classic two-way control valve mounting pattern
Progress
When installing flanges, make sure that there are no distortions. Excessive force must not be used to eliminate skew, otherwise the flanges of the instrument housing may be deformed.
During installation, make sure that the arrow on the body coincides with the direction of flow.
After installation, the device is opened, thoroughly washed and purged.
Check the sealing of the joints and stem stem assembly.
The health check of the device is done by connecting to the mains. The valve should operate five times at full speed without medium. All parts should move easily and without jerking.
Common installation errors and problems
Acquisition of products with inflated conditional pass (DU). Bandwidth above normal will adversely affect the accuracy of regulation.
When choosing a valve with a reduced nominal bore, it will not be able to give the desired steam flow rate at the set pressure indicators. This will lead to the fact that the pressure and temperature of the medium in the pipe after the locking device will become lower than the values \u200b\u200bnecessary for the normal functioning of the heating network.
Non-compliance with the technology during the installation of fittings.
These errors can cause instability in the operation of the control system and lead to malfunction of the valve and the actuator.
A steam trap must be installed in the steam pipelines in front of the control valves, which ensures the timely discharge of condensate.
During the installation period, do not weld in the pipeline with the valve installed so as not to damage the seals.
