Industrial gas emergency shut-off valve

The FCR type gas emergency shut-off valve (hereinafter referred to as solenoid valve) is an electrically actuated closing device, suitable for various gas sources such as pipeline gas and natural gas. The use of gas provides convenience to thousands of households, but due to various reasons, it has also brought about explosion events caused by gas leakage. In order to eliminate hazards in time before a disaster occurs, this device, under the control of a safe and reliable gas leakage alarm shut-off device, cuts off the gas source in time to ensure the life and property safety of you and your family.
Features
Encapsulated explosion-proof: Fundamentally eliminates spark generation, poses no safety hazard when installed on gas pipelines, and will not become an ignition source
Valve opening method: Manual reset, opening the valve requires on-site manual operation, conforming to the characteristics of gas accident handling
Valve closing requirement: Low-voltage DC permanent magnet drive for closing
Valve closing speed: Gas source can be cut off within 1 second
Valve closing control: Low-energy instantaneous drive, supports fire protection backup power operation mode, conforms to fire protection codes (used with a controller)
Signal output: On the two valve closing control lines, characteristic feedback signals of the valve switch status can be output
Holding method: Self-maintaining open/close status, no electricity required.
Manual valve closing: When power is off, it can be used as a manual shut-off valve
Strong vibration closing: The holding force for the valve open status can be adjusted to meet the requirement of automatic valve closing under strong harmful vibrations
Reliable sealing: Structurally adopts multi-stage sealing measures and precision processing to ensure air tightness and safety; Material-wise, specially uses NBR/FKM rubber (designed according to gas type), with 10-year aging resistance in urban gas environments
Reliable operation: The actuator performs 20,000 open/close cycles without failure
