The GSV series shut-off valve, a gas safety device , is suitable for medium and high pressure gas pipeline networks and gas systems in commercial and industrial users. It is widely used in both commercial and industrial installations using Natural Gas, LPG and other non-corrosive gases.
When any system abnormality causes the monitored pressure to reach a predetermined alarm threshold, the device automatically and rapidly shuts off the gas flow to ensure safety protection.
