The Sun Hydraulics RPGEMUV (Material Number: RPGEMUV) is a fast-acting, pilot-operated, balanced piston relief cartridge designed to protect hydraulic components from pressure transients. This normally closed valve opens rapidly when the inlet port pressure reaches the preset limit, directing flow to the tank port to control pressure rise. It features low pressure rise versus flow and a quick response time of approximately 2 milliseconds. The valve is suitable for cross-port relief circuits, accepting maximum pressure at port 2, although spool leakage should be considered in these applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen, and the valve is not recommended for load-holding applications due to potential spool leakage. The cartridge operates in a T-3A cavity with Series 2 capacity of up to 50 gallons per minute (200 liters per minute). It can handle a maximum operating pressure of 5000 psi (350 bar), with factory pressure settings established at 4 gpm (15 L/min). The valve's construction minimizes internal part binding due to excessive installation torque or machining variations. Back pressure on tank port 2 adds directly to the valve setting at a 1:1 ratio. Equipped with EPDM seals, this cartridge is intended for systems using phosphate ester fluids and should not be exposed to petroleum-based substances. The adjustment mechanism allows for up to five clockwise turns to increase settings, with detailed specifications on torque requirements for installation and adjustment components provided. This model weighs approximately .50 lb (0.25 kg) and utilizes Viton seal kits for maintenance.
