The Sun Hydraulics RPCCCNV (RPCCCNV) is a pilot-operated, balanced-piston relief cartridge designed for pressure regulation in hydraulic systems. This valve remains normally closed and begins to open to tank port 2 when the inlet pressure at port 1 reaches the preset valve setting, thereby throttling flow to maintain the desired pressure. Known for its precision and smooth operation, the RPCCCNV offers low pressure rise relative to flow and is moderately fast with a typical response time of 10 ms. It features interchangeable compatibility with all 2-port relief cartridges, except pilot reliefs, ensuring functional consistency across similar frame sizes. This model accepts maximum pressure at port 2 and is suitable for cross-port relief circuits; however, users should consider spool leakage in such applications. It has a minimum setting of 75 psi (5 bar) across all spring ranges but is not recommended for load-holding applications due to potential spool leakage. The back pressure on tank port 2 adds directly to the valve setting at a 1:1 ratio. The main stage orifice is designed to resist contamination. The RPCCCNV incorporates Sun's floating style construction, which minimizes internal binding risks due to variations in installation torque or machining discrepancies. For systems using phosphate ester fluids, cartridges configured with EPDM seals are available, although these seals are susceptible to damage from petroleum-based substances. With a capacity of up to 12 gpm (45 L/min) and maximum operating pressure of 5000 psi (350 bar), this cartridge valve offers robust performance suitable for various hydraulic applications. Installation requires a torque of 20-25 lbf ft (27-33 Nm), with adjustments made via an internal hex screw. The model weighs approximately .20 lb (.10 kg) and comes with optional Viton seal kits for enhanced durability under specific conditions.

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.
