ABSTRACT:
A pressure relief valve that is rotatable relative to the pressure relief system to allow flexibility in the connection of an outlet aperture in the pressure relief valve with a vent pipe in the building. A circumferential channel being formed on a conduit comprising a portion of the valve to receive a plurality of fasteners thereon for attaching the valve body to the conduit. Further, a tension relief bar having a pair of apertures is utilized to manually control the movement of a valve member relative to a valve seat within the valve body. One of the apertures being positioned for receiving a locking pin therein to hold the valve member apart from the valve seat. The capability to rotate and separate the valve body from the conduit allows for flexibility in servicing and connecting the valve body to the conduit.
