Electric actuator is a major component of electric pneumatic valve

Electric actuators and electric pneumatic valve is a concept that
electric actuator contains many, electropneumatic valve electric actuator just one type of one or a. Two concepts:

1, the electric actuator is a device driver; Electric pneumatic valve refers to the power to control the pneumatic valve, is a general designation
2, fitted with electric actuator pneumatic valve is called
electropneumatic valve electric actuator and a concept electric pneumatic valve?
is not a concept, electropneumatic valve refers to the pneumatic valve with electric actuator, electric actuator is only can be used in pneumatic valves electric actuator, it includes motor, retarding mechanism, manual mechanism, control mechanism, etc.
electropneumatic valve working principle?
it is 90 degrees of rotation of electric pneumatic valve, cock body to body, a circular hole or channel through its axis. Pneumatic valve in the line is mainly used to do electric pneumatic valve shut off, distribution, and change the flow direction of medium, it just has to rotate 90 degrees of operating and small rotational torque can be closed tightly. Pneumatic valve is suitable to do the most switch, used to cut off the pneumatic valve, pneumatic valve development have designed to make it with throttling and control flow, such as V pneumatic valve. Electropneumatic valve itself is the main characteristics of compact structure, reliable sealing, simple structure, convenient maintenance, and facial sealing surface often in the closed state, not easily be medium erosion, easy operation and maintenance, applicable to water, solvent, acid and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, widely used in various fields. Pneumatic valve pneumatic valve can be integral, also can be combined.
principle of electric pneumatic valve:
electropneumatic valve is made up of cock type pneumatic valve and electric actuator, pneumatic valve pneumatic valve body structure to rotate 90 degrees of pneumatic valve core, line of electric actuators for 0 - Unit 10 ma standard signal, electric driven gear, worm gear and worm rotation torque to switch box pneumatic valve adjustment. Its use is mainly by electrical discharge and adjusting operation.
electropneumatic valve components:
the commonly used how rotary electric actuator, single rotary, intelligent, straight travel quarter-turn actuators, electric actuators, explosion-proof actuators, small actuators, etc. Pneumatic valve, pneumatic valve mainly include floating fixed pneumatic valve, pneumatic valve, O V pneumatic valve pneumatic valve, tee, etc. Its execution with the pneumatic valve configuration, produce the diversification of products. Can also add a control box for its use as a remote operation, at the same time to add on the actuator accessories can also achieve more features, such as adding electrical locator for flow control, pneumatic valve position resistance/current converter can be used for sensing and control of the pneumatic valve position opening, the handwheel institutions can be manual operation, in the absence of current commonly used accessories and bushing, explosion-proof switch, etc. First selection can undertake choosing according to the working condition.
electropneumatic valve application:
electropneumatic valve is now in the oil, gas, pharmaceutical, food, water and electricity, nuclear power, electricity, water supply and drainage, heating, metallurgical and other industries widely used, is a vital urban construction machinery products. At the same time is indispensable to construction of science and technology products. Which occupies a lot of market share, mainly because of strong electric pneumatic valve, small volume, reliable sex Eng, large flow capacity, light and pleasant, but a variety of reasons, such as remote control electric pneumatic valve is not only a throttle, globe, cut off, on and off, the good product flow, or flow control system of choice for his goods. It has pressure, heat resistance, corrosion resistance, small flow resistance, long service life, wide application range, and other characteristics.
