An adjustable pressure relief valve for use in a fluid pressurized system. The pressure relief valve has a valve body with a passage that terminates at inlet and outlet ends. The passage includes a valve chamber, a valve seat at the inlet end, and a valve base adjustably secured proximate the outlet end. A valve head sealingly engages the valve seat by a spring that is interposed between the valve head and the valve base. The valve body is constructed and arranged for use as an end cap in a flexible pressurized system, such as a pneumatic pipeline plug.
