Specifications:
1) Fluid: Natural Gas, Coal Gas, Liquefied Petroleum Gas
2) Size: 25 to 400 mm
3) Ambient Temperature: -20 to 60 º C
4) Max. Working Pressure: 500mbar or 6bar
5) Body Material: Stainless Steel, Casting Steel, Alloy Aluminum
6) Response Time: Below 1 S
Features:
1) Widely applied in gas pipeline.
2) Explosion proof solenoid valve
3) Low power consumption: Normally open type, just need a split second of electricity to shut off.
4) Safety and reliability: After shut off, it is self-locked, not need electrical source.
5) Easy operation: Manual reset to resupply gas.
Working principle:
This solenoid valve is normally open and pulse-trigger mode. It has function of self-lock and manual reset in the event of emergency. When the coil is electrified instantly, tie rod lose support. Under spring force, solenoid valve shut off quickly and self-locked. Then if remove electrical source, the solenoid valve cannot be opened unless using manual reset to pull tie rod up.
