ABSTRACT:
A gas valve assembly has a safety valve and two controlled valves connected in series. A first of the controlled valves is electromatic and a second is a conventional pressure controlled valve. A control knob provides for manual control of the safety valve and for locking the first electromagnetically controlled valve in an off position. The manual control knob, when in the off and pilot positions, causes a stop member to be moved against the movable core member of the electromagnetic operator to hold the electromagnetic controlled valve in an off position.
