Pneumatic control valve and the electric pneumatic valve contrast adjustment

pneumatic regulating pneumatic valve with compressed air as power source, pneumatic actuators, pneumatic valve is electric regulation by electric actuators and adjust a mix of pneumatic valve connection. It is not hard to see the pneumatic regulating pneumatic valves and electric pneumatic valve actuator options exist differences. Below pneumatic regulating pneumatic valve and electric pneumatic valve in power, use, maintenance and so on various aspects of comparison:
pneumatic adjustment in the moment than the electric pneumatic valve movement adjustment pneumatic valves, pneumatic 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 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 valve and pneumatic regulating 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. The regulation of electric actuators response fast enough, so regulating pneumatic valve with pneumatic actuator than electric actuator applications.
& #; & #; Late operation and maintenance cost of electric regulating pneumatic valve pneumatic is much higher.
