The Sun Hydraulics RPCCLBE (RPCCLBE) is a pilot-operated, balanced-piston relief cartridge designed to regulate pressure in hydraulic systems. These normally closed valves open to tank port 2 when the pressure at inlet port 1 reaches the designated setting, throttling flow to maintain the desired pressure level. Known for their accuracy and low pressure rise versus flow, these valves operate smoothly and quietly with moderate speed. They are interchangeable with other 2-port relief cartridges of the same frame size, sharing the same flow path and cavity configuration. The RPCCLBE can handle maximum pressure at port 2, making it suitable for cross-port relief circuits, although spool leakage should be considered in such applications. The valve's minimum setting is 75 psi (5 bar), but it is not recommended for load-holding applications due to potential spool leakage. Back pressure on tank port 2 directly adds to the valve setting in a 1:1 ratio. The main stage orifice is protected against contamination, enhancing reliability. Cartridges equipped with EPDM seals are compatible with phosphate ester fluids but must avoid petroleum-based substances that could damage the seals. Sun's floating style construction minimizes internal part binding caused by excessive installation torque or machining variations in cavity/cartridge setups. The RPCCLBE has a capacity of 12 gpm (45 L/min) and operates at a maximum pressure of 5000 psi (350 bar), with a typical response time of 10 ms. Maximum valve leakage at 110 SUS (24 cSt) is specified as 2 in\u00b3/min (30 cc/min) at 1000 psi (70 bar). Adjustments can be made via an internal hex screw, with five clockwise turns required to increase settings. The valve has a hex size of 3/4 inch (19.1 mm) and requires an installation torque between 20-25 lbf\u00b7ft (27-33 Nm).

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.
