Electropneumatic valve category is wide, there are different control of external regulation and switch type actuator, pneumatic valve electric pneumatic valve and electric switch.
Electric pneumatic valve is suitable for the pipeline pressure difference is big, strict sealing of the switch and cut off the pipeline media appearances and fluid process control system.
Electric pneumatic valve is the process of industrial automation control pressure pipe components, electric pneumatic valve is typically used for pipeline remote switch or adjusting control of the medium.
Electropneumatic valve regulating main electrical pneumatic valve, pneumatic valve, electric explosion-proof electric high pressure pneumatic valves, electric 3-way pneumatic valve, and other series.
Electric actuator adopts integrated structure, the built-in servo system, do not need to match servo amplifier, enter 4
Or 1 to 20 ma control signal
5 VDC and 220 vac power to control the operation.
Electric pneumatic valve body small, light, good performance, supporting the advantages of simple, large flow capacity.
Electric pneumatic valve can be used to working temperature:
- 20 ℃ to + 200 ℃ ( + 350 ℃ to + 700 ℃ special seal) , the pressure of work:
PN1. 6 - PN42。 The occasion of 0 mpa.
the electric pneumatic valve, pneumatic valve, electric explosion-proof electric high pressure pneumatic valves, electric 3-way pneumatic valve is mainly suitable for water, steam, air, gas, oil and petrochemical products, the adjustment of the corrosive medium or cut off.
electric pneumatic valve actuator is to realize the programmable electric pneumatic valve, indispensable driving control device, automatic control and remote control by travel, its movement process to control the torque, etc. Due to the working characteristic of electric pneumatic valve actuator and utilization depends on the type and characteristics of pneumatic valve, it is the right choice of pneumatic valve actuator, is very important to prevent overload phenomenon.
actuator output torque is to select the main parameters of electric actuators, pneumatic valve actuator output torque should be selected 1 operating torque. 2 to 1. 5 times. Next, should according to the different conditions of use of pneumatic valve, choosing the proper opening and closing speed, which can prevent the pneumatic valve actuator opening and closing too fast to produce water hammer phenomenon.
electric pneumatic valve actuator has its special requirements, which must be able to limit torque ( Axial force) And the rotation Angle. When the electric actuator specifications was determined, the control torque is determined. Generally run in a predetermined time, the motor will not overload. But as the following conditions may lead to overload: one is the low voltage power supply and can not get the required torque, the motor stop running; 2 it is wrong to set torque limit, make its torque is greater than the stop, cause continuously produce too large torque, the motor stop running; 3 it is intermittent use, the heat generated by the savings, more than the allowed temperature to rise of the motor; Four is a torque limit institutions circuit for some reason fails, the torque is too large; Five is the use of the environment temperature is too high, the relatively decreased motor heat capacity.
