  • Patent number: 5241981
    Abstract: A pressure responsive relief valve assembly for relieving an overpressure condition in a piping system includes a valve and a mounting saddle formed as a unit body with a pipe tapping conduit projecting outwardly therefrom for providing communication between the interior of a piping system and the valve, an opposing saddle, and bolts or other fasteners for clamping the saddles to opposite sides of a pipe. Upon tightly clamping the valve assembly to the pipe, the pipe tapping conduit punctures the pipe wall to communicate the valve with the interior of the pipe. A gasket is provided intermediate the valve assembly and the pipe to prevent leakage. The assembly may thus advantageously be installed on a pipe without interrupting fluid flow therethrough.
