The Sun Hydraulics RPECREV (RPECREV) is a pilot-operated, balanced piston relief cartridge valve designed for precise pressure regulation in hydraulic systems. This normally closed valve opens to the tank port when the inlet pressure reaches the set point, effectively throttling flow to maintain consistent pressure levels. Known for its accuracy and low-pressure rise versus flow, this valve operates smoothly and quietly at a moderate speed. It is suitable for cross port relief circuits, accepting maximum pressure at port 2; however, it is not recommended for load holding applications due to spool leakage. The main stage orifice is safeguarded by a 150-micron stainless steel screen, enhancing durability and performance. This cartridge valve features adjustable settings via W or Y controls, with optional special settings available to define maximum settings. It incorporates corrosion-resistant materials with options for external stainless steel or zinc-nickel plated components identified by specific model code suffixes. Additionally, the Sun floating style construction minimizes internal binding risks due to excessive installation torque or machining variations. The RPECREV fits into a T-10A cavity and has a capacity of 25 gpm (95 L/min) with factory pressure settings established at 4 gpm (15 L/min). Its maximum operating pressure reaches up to 5000 psi (350 bar), with a typical response time of 10 ms. The valve exhibits minimal leakage at maximum conditions and offers user-friendly adjustments through an internal hex adjustment screw and locknut. The cartridge weighs approximately 0.30 lb (0.15 kg) and comes with Viton seals as part of its standard configuration.

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.
