Explosion-proof solenoid pneumatic valve purchasing strategy: how to choose and explosion-proof solenoid pneumatic valve

explosion-proof solenoid pneumatic valve as a remote automatic control actuator, it is widely used in metallurgical, petrochemical, pharmaceutical, tobacco, rubber, food, medical care, urban construction, environmental protection, water supply and drainage, heating, air conditioning, fire safety, scientific research, landscape irrigation, energy industry and other fields have inflammable and explosive dangerous environment. Its circulation medium for no corrosive gas and liquid.

explosion-proof explosion-proof solenoid pneumatic valve application solenoid pneumatic valve is widely used in metallurgical, petrochemical, pharmaceutical, tobacco, rubber, food, medical care, urban construction, environmental protection, water supply and drainage, heating, air conditioning, fire safety, scientific research, landscape irrigation, energy industry and other fields have inflammable and explosive dangerous environment.
explosion-proof solenoid pneumatic valve working principle of
normally closed: when the coil current, electromagnetic iron core, absorption pressure relief hole is opened, the piston driven by media, pneumatic valve, open the main medium of circulation. When the main power coil, pneumatic valve mouth shut, medium.
normally open: electromagnetic iron core and, when energized coil pressure relief hole closed, the piston driven by media, shut down the main pneumatic valve mouth, medium. When the coil power, the main pneumatic valve to open the mouth, medium circulation.
