Solenoid operated valve and shut-off device










Image Number 2 for United States Patent #4180241.

A combined solenoid operated valve and shut-off device including a valve housing defining a fluid inlet, a fluid outlet, and a valve seat therebetween. Located within the housing is a valve closure movable between a closed position in which fluid flow between the inlet and outlet is prevented and an open position wherein such flow is permitted. Controlling movement of the valve closure is a valve operator that includes a magnetic plunger for cycling the valve closure between open and closed positions in response to an electrical signal and a shut-off mechanism activatable to lock the valve closure in its closed position in response to a predetermined fluid pressure at the inlet. After activation of the shut-off mechanism, reopening of the valve to initiate fuel flow between the inlet and outlet requires actuation of a manual reset device.
