3 Features
- When an earthquake occurs, this device
shuts off the LP gas supply at the entry point
- f gas line.
SHAKING!! Earthquake!!
Cylinder Pressure Flow Middle Pressure Flow No Flow
Shut-off Activated
- A combination of two elements with
different operating characteristics provides this sensor with stability.
