Seismic sensor for solenoid valve

Device that, combined with a sefety valve closes the gas passage for following reasons: • seismic event (with time and frequency analysis on a 3 axes acceleration) • remote control ( f. e . g a s d e t e c t o r, emergency lockup), The solenoid valve also includes also a relay alarm exit to be used for remote signals and to stop the power supplies, avoiding, in this case possible fire and explosions sources. The sensor can be monted with normally closed/open manual reset solenoid valves. It is possible to apply the kit seismic sensor even on solenoid valves already installed.
