Abstract
A gas pressure relief valve assembly with a normally closed check valve received in a main body. An actuator pin slidably received in a guide body threadably carried by the main body may be advanced to open the check valve and retracted to permit the check valve to close. A knob connected to the actuator pin and threadably carried by the guide body may be manually rotated in opposite directions to advance and retract the actuator pin. Rotary loosening of the threaded knob and/or loosening of the threaded guide body will retract the actuator pin and prevent opening of the check valve.
