Earthquake-Proof Automatic Gas Shut-Off Devices

The Earthquake Sensor & Shut Off Valve Earthquake-Proof Shut Off Valve Earthquake-Proof Detecting Sensor

Lineup EQT-25 EQH-25 EQ-25

3 Features

• When an earthquake occurs, this device shuts off the LP gas supply at the entry point of gas line.

SHAKING!! Earthquake!! Shut-off Cylinder Pressure Flow Activated Middle Pressure Flow No Flow

• A combination of two elements with different operating characteristics provides this sensor with stability.

Activated Set Resetting ↕ ↔

• This device does not require electricity. Explosion-proof certification is not necessary.
