Pilot solenoid valve is formed in the valve working medium itself using the control loop

Extensive use of a conventional pneumatic actuator and electric control loop, which increases the complexity of the system, and the pilot solenoid valve is formed in the valve using the control circuit of the working medium itself, the structure is a simple one. Over the past number of technical parameters and abroad solenoid valve is also restricted, domestic solenoid valve diameter has been extended to 30Omm;  electri cenergy meter  as low as 200 ℃, up to 450 ℃; Working pressure from vacuum to 25MPa. Action time from ten seconds to a few milliseconds. These new  electric meter  in technology can completely replace the bulky and expensive two control valves and pneumatic quick disconnect switch valve, electric switch valve can also be partially substituted continuously adjustable pneumatic,  Circuit breaker  valve. Foreign textile, light industry, construction and other industries have a large number of switching solenoid valve, and metallurgy, chemical industry is the first in the auxiliary systems using more and more solenoid valve.
