Pneumatic pneumatic valve and electric pneumatic valve actuation moment

the aerodynamic moment than electric pneumatic valve, pneumatic valve movement pneumatic pneumatic valve switching speed can be adjusted, simple structure, easy maintenance, in the process of action for buffer characteristics of the gas itself, is not easy to damage due to get stuck, but must have a gas source, and its control system is more complicated than the electric pneumatic valve. Pneumatic pneumatic valve response is sensitive, safe and reliable, many factory of high control requirements for pneumatic instrumentation control components set the compressed air station. Electric is to electricity. Electric pneumatic valves and pneumatic pneumatic valve is the essential difference between using a different drive, actuators, and adjust the pneumatic 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 pneumatic valve, because of the high security requirements, and the price is cheap, with intelligent positioner on can bus, control method is also simple. Electric pneumatic valve actuator power supply for power supply, if the circuit board or motor failure prone to spark, so commonly used in the occasion of environmental requirements is not high and there was no danger. Pneumatic 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 pneumatic valve position. Pneumatic actuators and electric actuators to adjust performance comparison, pneumatic actuators response speed faster, more suitable for application in operating conditions, so the production adjustment of pneumatic valve manufacturers are supporting production of pneumatic actuators and at the same time.
