134 Series Relief Valves

Parker 134 Series relief valves are diaphragm type valves that relieve excess pressure, thereby protecting pneumatic circuits and systems. These relief valves are ideal for applications where gradual proportional relief is required. They feature a compact design for narrow spaces and top adjustment knob to adjust relief range. The adjustment knob can be locked / unlocked via a push-pull mechanism and can be rotated in both clockwise & counter-clockwise directions to stop and start bleeding, respectively. These valves have a sensitive diaphragm for accurate operation.

Relief Valves

Pressure relief valves are designed to control or release built-up pressure in the system which may otherwise damage pipelines and equipment. Raptor Supplies offers a wide range of relief valves including shut off, safety, drain & pressure valves from Apollo, Watts, Parker, Milton Industries, Hayward, Oil Safe, Campbell & more. Apollo safety relief valves are designed according to ASME Section IV standards for the protection of steam boilers. These bronze constructed valves feature metal to metal, PCTFE or elastomer O-ring seating, thereby having a wide pressure and temperature range. They are capable of withstanding a maximum pressure of 1200 PSI and are available in inlet sizes ranging from 1/2 to 3 inches. Watts adjustable relief valves are designed to release pressure (up to 200 PSI) when the set internal pressure is encountered in systems containing air, oil or water. Watts 1450F Series combination fill and relief valves feature a silicone disc to provide positive seating and leakproof operation. These valves are available in bronze, brass, iron, lead free bronze and lead free brass variants.
