ABSTRACT:
A bleed screw is built into a solenoid actuator used to control a diaphragm controlled valve so that the valve can be opened manually by means of the bleed screw or remotely or automatically through use of the solenoid. Both the bleed screw and the solenoid actuator are configured to relieve diaphragm pressure maintaining the valve normally closed so that either or both can open the valve.
