1 in the moment than electric valve, pneumatic valve, pneumatic valve switching speed can be adjusted, simple structure, easy maintenance, action for buffer characteristics of the gas itself in the process, not easy to damage due to get stuck, but must have a gas source, and its control system is more complicated than the electric valve.
Pneumatic valve response is sensitive, safe and reliable, many factory of high control requirements for pneumatic instrumentation control components set the compressed air station.
Pneumatic valve actuator power supply for gas source, gas source comes from air compressor, the locator converts electrical signals into the pneumatic control signal, drive the pneumatic actuators which can adjust the valve position.
2, electric valve actuators are source of power for power supply, if the circuit board or motor failure prone to spark, so commonly used in the environmental requirements is not high and there is no danger of pneumatic actuators and electric actuators to adjust performance comparison, pneumatic actuators response speed faster, more suitable for application in operating conditions, so the manufacturer of the regulator are produced at the same time a set with pneumatic actuators.
3, the regulation of electric actuators response fast enough, in the case of ROTORK, external regulation executor adjustment is only 1200 times per hour, and so on control valve with pneumatic actuator than electric actuator applications.
4 pneumatic valves, electric valves and the essence of the difference between using a different drive, actuators, and regulating valve itself.
Cooperate with different working condition of actuators is mainly, such as chemical and other occasions with explosion-proof requirements, is the most used pneumatic valve, because of the high security requirements, and the price is cheap, with intelligent positioner on can bus, control method is also simple.
