Valve device for interrupting the gas supply in a feed line

摘要

The device has a valve i.e. bistable 3/2 way valve (17), controlled by external signals such as electric signals provided by a sensor e.g. gas sensor, and attached to a bus. A part of energy is drawn from a battery or rechargeable battery for switching the valve, and a pressure controller (18) is inserted into a supply line. The valve is attached to the pressure controller that is provided with a low pressure shut off that is activated through the valve device. An input (1) of the valve is connected with a supply of the supply line.
