The difference between the electric pneumatic valve and pneumatic pneumatic valves

electric brake pneumatic valve is a kind of linear movement of pneumatic valves, it has to do with Z type rotary actuators are more suitable, had an 'on/off' switch and intelligent. The pneumatic valve operation simple is one of the most common pneumatic valve opening and closing, which makes use of the upper and lower ram working fluid in the pipeline to switch on and off. Widely used in electric power, metallurgy, petroleum, chemical industry, paper making, sewage treatment and other departments.
pneumatic brake valve is a pneumatic actuators, double cylinder and manual with buffering mechanism and its protection agency, the pneumatic valve with double cylinder structure, its compared with single cylinder type pneumatic brake valve, the doubling of lifting force. This is fundamentally solved some of the single cylinder pneumatic brake valve pneumatic valve body wedge die and won't open.
the difference between electric pneumatic valves and pneumatic pneumatic valve:
in the moment than the electric pneumatic valve, pneumatic pneumatic valve action, 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. 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 valve actuator, electric power supply 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 are adjustable performance comparison, pneumatic actuators response speed faster, more suitable for application in operating conditions, so the production adjustment of the pneumatic valve manufacturers are supporting production of pneumatic actuators and at the same time.
and the regulation of electric actuators response fast enough, the regulation on the pneumatic valve with pneumatic actuator than electric actuator applications.
pneumatic valves, electric 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.
