ABSTRACT:
In a pressure relief valve, a valve body is provided with an axial bore counterbored from each of its ends to form an inlet port for connection with a container of gas to be monitored and for receiving a valve assembly at its other end opening the valve axial bore in response to the valve being unseated by a predetermined pressure in the container. The valve assembly includes a piston-type valve normally seated in the bore by a collapsible strut or pin interposed between the valve and a plug member secured to the downstream end portion of the valve bore.
