The Sun Hydraulics RPCCLWV (RPCCLWV) is a pilot-operated, balanced-piston relief cartridge designed to regulate pressure in hydraulic systems. This normally closed valve begins to open to tank port 2 when the inlet port 1 pressure reaches the set threshold, effectively throttling flow to maintain desired pressure levels. Known for its accuracy and low-pressure rise versus flow characteristics, this valve operates smoothly and quietly with moderate speed. It features a maximum operating pressure of 5000 psi (350 bar) and a response time of approximately 10 ms. The valve is suitable for cross-port relief circuits, accepting maximum pressure at port 2, though spool leakage should be considered in such applications. The RPCCLWV is not recommended for load-holding applications due to potential spool leakage. The minimum setting for all spring ranges is 75 psi (5 bar), with back pressure on port 2 directly adding to the valve setting at a 1:1 ratio. The main stage orifice is protected against contamination, ensuring reliable operation. Cartridges equipped with EPDM seals are specifically designed for systems using phosphate ester fluids; exposure to petroleum-based substances can damage these seals. This cartridge incorporates Sun's floating style construction, minimizing internal binding risks due to installation torque or machining variations. It fits into cavity T-162A and has a capacity of 12 gpm (45 L/min). The factory pressure settings are established at a flow rate of 4 gpm (15 L/min). Installation requires a torque between 20-25 lbf ft (27-33 Nm), with an adjustment screw internal hex size of 5/32 in. (4 mm) and locknut hex size of 1/2 in. (12.7 mm). The model weight is .20 lb (.10 kg), and it includes a Viton seal kit option under part number 990162006.

Pilot-operated, balanced-piston relief cartridges are normally closed pressure regulating valves. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to regulate the pressure. These valves are accurate, have low pressure rise vs. flow, they are smooth and quiet, and are moderately fast.
- All 2-port relief cartridges (except pilot reliefs) are physically and functionally interchangeable (same flow path, same cavity for a given frame size).
- Will accept maximum pressure at port 2; suitable for use in cross port relief circuits. If used in cross port relief circuits, consider spool leakage.
- Minimum setting is 75 psi (5 bar) for all spring ranges.
- Not suitable for use in load holding applications due to spool leakage.
- Back pressure on the tank port (port 2) is directly additive to the valve setting at a 1:1 ratio.
- The main stage orifice is protected against contamination.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
