MECHANICAL ACTUATED SEISMIC VALVE
GAS NETWORKS AND INDUSTRIAL PIPELINES
ESKA EMV Series Earthquake Valve is a shut-off valve which is activated during seismic oscillation. Activation and non-activation waves are defined in TS 12884 Turkish Standard. This Turkish standard was created based on ANSI Z11 standard in United States.
Once mechanical actuation system senses the seismic oscillation, valve shuts the gas off and you should rearm manually in order to reactivate gas flow. This valve basicaly is a manual reset, normally open gas valve. Main aim is to decrease the risk of gas leakage related fire, when earthquake occurs. In countries this safety system is available, main regulation is done by fire safety department.
