A right angle relief valve body for high pressure fluid is provided with a bushing type valve seat in the inlet port. A piston valve having rod guide end portions is longitudinally slideable in the valve body toward and away from the inlet port. A sleeve extension of one rod end portion, having longitudinal wall slots intermediate its ends and slidable in the valve seat, closes the inlet port in a first fluid monitoring position and opens the valve fluid passageway when in a second position in response to a predetermined value of fluid pressure acting on a pressure relief member opposite the inlet port.

[ What is claimed is:] [1.] A heavy duty relief valve for monitoring fluid under high pressure, comprising:a valve body adapted to be connected with a fluid container and having a first bore forming an inlet port at the upstream end and having a second bore intersecting the first bore and forming an outlet port and a fluid passageway therebetween;a valve seat adjacent the inlet port;a piston valve having rod-like axial end portions longitudinally slideable in the first bore toward and away from the inlet port and having a slotted wall sleeve at one end portion normally closing the fluid passageway; and,a fluid pressure sensing means secured to said body opposite the inlet port and normally maintaining said piston valve in inlet port closed position for releasing said piston valve and opening the fluid passageway in response to fluid pressure above a predetermined value.
