Product Description：

The electromagnetic gas emergency shut-off valve is a safety emergency cut-off device for gas pipelines. It can be connected to gas leakage alarm systems, fire protection systems and other intelligent alarm control terminals, enabling on-site and remote emergency gas cut-off via automatic or manual operation to guarantee the safety of gas pipeline transmission and gas utilization.

This product complies with GB 3836.1-2021 Explosive atmospheres — Part 1: General requirements for equipment, GB 3836.9-2021 Explosive atmospheres — Part 9: Equipment protected by encapsulation "m" and CJ/T 394-2018. It features rapid cut-off, excellent sealing performance, low power consumption, high sensitivity, reliable operation and easy use. The valve can only be opened manually, which conforms to safety management regulations and accident handling requirements.

Product Features：

※ Encapsulated explosion-proof design: Prevents spark generation for enhanced stability and reliability.

※ Valve opening mode: Manual reset to prevent accidents.

※ Holding mode: Bistable structure for stable operation in both open and closed states.

※ Valve closing mode: Automatic closing upon power failure, as well as automatic and manual closing via external control signal.

※ Closing speed: Gas supply can be cut off within 1 second.

※ Independent pressure relief: When the pressure difference across the valve is excessive, the valve can be opened after activating the pressure relief valve, preventing gas venting to atmosphere and eliminating potential safety hazards.

※ Zero differential pressure closing: The valve can perform closing action under zero differential pressure to avoid failure to close caused by minor leakage.※ Seal type: Multi-stage sealing structure.

※ Sealing performance: Tighter sealing under higher pressure, ensuring stable operation under various working conditions.

※ Operational reliability: Maintains effective performance for more than 10 years.
