Abstract
The invention is directed to a gas valve comprising a valve body with a gas inlet, a gas outlet and a gas passage connecting the inlet with the outlet, gas shut-off device in the gas passage, with a seat on the valve body and a movable closure member, an electromagnetic actuator with an electric coil and a movable plunger configured for actuating the closure member of the gas shut-off device, a sleeve extending through the coil and slidably receiving the movable plunger and wherein the sleeve is made of austenitic stainless steel. This avoids embrittlement problems when using the valve with hydrogen under high pressure.
