In the moment than electropneumatic valve pneumatic pneumatic valve action

than large pneumatic pneumatic valve electric pneumatic valve, pneumatic valve pneumatic switch speed adjustable, simple structure, convenient maintenance, because itself is not easy to damage during the operation, due to the cushioning properties of the gas card operating torque, but must have a gas source, and control systems are also much more complex electric pneumatic valve. Sensitive reaction pneumatic pneumatic valve, safe and reliable, high control requirements of plants, set the air station many pneumatic control components. Is power. Between electric pneumatic valve, pneumatic pneumatic valve is to use a different drive, this is the essential difference between actuators, and pneumatic control valve itself is no different. With different actuators, the main work proves that the chemical conditions such as the required occasion is the most used pneumatic pneumatic valve, high security requirements, but also cheap intelligent positioner can be on the bus, control is simple. Electric pneumatic valve actuator of the source of power, if the circuit board or easy to cause electrical failure, it is generally used in low demand of environment, and there was no danger. Pneumatic valve pneumatic actuator air power, sources of gas compressor, the locator signal into electric pneumatic control signal, drive pneumatic valve actuator. In pneumatic actuator, electric actuator performance comparison of adjustment, the pneumatic actuators response is faster, more suitable for application in working condition adjustment, control of the pneumatic valve manufacturers also produce supporting pneumatic actuators. Electric actuator response fast enough control to trafigura, for example, the actuator adjustment to adjust how many times per hour, only The Times, so the adjustment and pneumatic actuator electric pneumatic valve actuator applications is not more.
