About This Product

By combining a seismic shutoff valve and a seismic sensor, it functions as a seismic automatic gas shutoff device. If an earthquake occurs that exceeds the set acceleration, the gas will be automatically shut off. It operates by using the natural pressure of the supplied gas without using any other power sources such as electricity, hydraulic pressure, or compressed air.

■Seismic shutoff valve (shutoff part)

[Seismic cutoff valve] is the "shutoff part" of the seismic automatic gas cutoff device, and when an earthquake occurs and the [seismic sensor] is activated, the seismic cutoff valve and the seismic sensor are connected. This device releases the sealed operation gas pressure and plays the role of shutting off the supply gas. *A seismic shutoff valve with a "pressure switch with transmitting function" that transmits the gas shutoff operation can also be produced as an option.

■EQH series for high pressure

This type is installed on the high pressure line of the LP gas supply (before the single stage regulator).
