XF3 Series Gas Emergency Shut-off Solenoid Valve

The gas emergency shut-off solenoid valve is a safety emergency shut-off device for gas pipelines. It can be connected to the gas leakage alarm system or to the fire protection and other intelligent alarm control terminal modules to achieve on-site or remote automatic/manual emergency cut-off of the gas source to ensure gas safety.
