EMV Mechanical Actuated Seismic Valve

Series EMV Mechanical Actuated Seismic 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 is created based on ANSI Z11 standard in United States. Once mechanical actuation system sense the seismic oscillation, valve will shut the gas off and you should rearm manually in order to reactivated gas flow. This valve basically is a manual reset, normally open gas valve. Main aim to decrease the risk of fire related to gas leakage, in case of earthquake occurs. In countries that this safety system is available, main regulation is done by fire safety department.
