The Sun Hydraulics RPEEJWV (RPEEJWV) is a fast-acting, pilot-operated, balanced piston relief cartridge designed to protect hydraulic components from pressure transients. This normally closed, pressure-limiting valve opens rapidly when the inlet port pressure reaches the valve setting, diverting flow to the tank port to limit pressure rise. It features a low pressure rise versus flow and offers quick response times, typically around 2 milliseconds. This model can handle a maximum operating pressure of 5000 psi (350 bar) and has a capacity of 25 gpm (95 L/min). The main stage orifice is safeguarded by a 150-micron stainless steel screen. The RPEEJWV is suitable for cross-port relief circuits but not recommended for load-holding applications due to potential spool leakage. The backpressure on the tank port directly influences the valve setting at a 1:1 ratio. It incorporates Sun's floating style construction to reduce internal binding risks from excessive installation torque or machining variations. The valve is adjustable throughout its range using W or Y controls, with an option for a special maximum setting. Physically and functionally interchangeable with other two-port relief cartridges of the same frame size, this model ensures compatibility across various configurations. Installation requires specific torque settings: 30\u201335 lbf ft (41\u201347 Nm) for the valve and 80\u201390 lbf in. (9\u201310 Nm) for the locknut. It features an internal hex size adjustment screw of 5/32 in. (4 mm) and weighs approximately .30 lb (.15 kg). For maintenance, it uses Viton seal kits like Cartridge: Viton: 990010006.
