The Sun Hydraulics RPGCCVV/AP (RPGCCVV/AP) is a pilot-operated, balanced-piston relief cartridge designed for pressure regulation in hydraulic systems. This normally closed valve begins to open to the tank port when the inlet port pressure reaches the set level, allowing it to throttle flow and regulate pressure effectively. Known for its accuracy and smooth operation, this valve features a low pressure rise versus flow and is moderately fast in response time, typically around 10 milliseconds. It's important to note that while it can handle maximum pressure at port 2, it's not suitable for load-holding applications due to potential spool leakage. The RPGCCVV/AP model offers versatility with interchangeable physical and functional attributes across similar frame sizes, making it suitable for cross-port relief circuits\u2014though spool leakage should be considered in such applications. The main stage orifice is protected by a 150-micron stainless steel screen, enhancing durability and performance reliability. Additionally, this model supports configurations with EPDM seals for compatibility with phosphate ester fluids but should avoid exposure to petroleum-based substances to prevent seal damage. For environments prone to corrosion, this cartridge can be configured with external stainless steel components (suffix AP) or zinc-nickel plated components (suffix LH). The valve's construction minimizes internal binding risks due to excessive torque or machining variations. It has a capacity of 50 gpm (200 L/min) and operates at a maximum pressure of 5000 psi (350 bar). Installation requires a hex size of 1-1/8 inches with an installation torque between 45-50 lbf ft (61-68 Nm). Adjustments are facilitated via an internal hex screw with specific torque requirements for secure operation.

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.
- Main stage orifice is protected by a 150 micron stainless steel screen.
- 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.
- 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.
- W and Y controls (where applicable) can be specified with or without a special setting. When no special setting is specified, the valve is adjustable throughout its full range using the W or Y control. When a special setting is specified, this setting represents the maximum setting of the valve.
- Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP for external stainless steel components, or /LH for external zinc-nickel plated components. See the CONFIGURATION section for all options. For further details, please see the Materials of Construction page located under TECH RESOURCES.
- 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.
