The Sun Hydraulics RPCCKWV (RPCCKWV) is a pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve opens to the tank port when the inlet pressure reaches the set threshold, effectively throttling flow to maintain desired pressure levels. Known for its accuracy and smooth operation, the RPCCKWV features low pressure rise against flow and moderate response speed, making it suitable for applications requiring reliable pressure control. It is interchangeable with other 2-port relief cartridges of similar frame sizes, allowing for versatile use across different systems. This valve can handle a maximum operating pressure of 5000 psi (350 bar) and has a capacity of 12 gpm (45 L/min). The minimum setting is 75 psi (5 bar) across all spring ranges. While it is effective in cross-port relief circuits due to its ability to accept maximum pressure at port 2, users should consider spool leakage when applying it in such configurations. It is not recommended for load-holding applications because of this leakage characteristic. The RPCCKWV's design incorporates Sun's floating style construction to prevent internal part binding due to excessive installation torque or machining variations. The main stage orifice is protected against contamination, ensuring durability and longevity. For systems using phosphate ester fluids, cartridges configured with EPDM seals are available; however, these seals should not be exposed to petroleum-based substances as they may incur damage. Installation requires a torque of 20-25 lbf ft (27-33 Nm), with adjustments made via an internal hex screw and secured by a locknut torqued at 80-90 lbf in (9-10 Nm). This valve offers reliable performance with minimal leakage at specified conditions and provides an efficient solution for managing system pressures in various hydraulic applications.

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.
