Valve shutter is a safety system developed to prevernt secondary accidents due to earthquakes, and to forestall gas explosions and gas poisoing due to gas leaks, using an emergency shutoff valve on the gas cylinder.

Having thoroughly considered explosion prevention, the operating signals use air pressure so that compressed air, nitrogen gas, etc.(0.29MPa) can be used within the plant, and a power spring is used in the shutoff valve mechanism.

One-touch mounting on existing gas cylinders is possible.
