The Sun Hydraulics RPECMAV (Material Number: RPECMAV) is a pilot-operated, balanced-piston relief cartridge designed for pressure regulation in hydraulic systems. This normally closed valve opens to the tank port when the inlet pressure reaches the set point, thus throttling flow to maintain desired pressure levels. Known for its accuracy and low-pressure rise versus flow characteristics, it operates smoothly and quietly with moderate speed. The RPECMAV cartridges are interchangeable with other 2-port relief cartridges of similar frame size, enhancing compatibility across systems. They can handle maximum pressure at port 2, making them suitable for cross-port relief circuits; however, users should consider spool leakage in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen, though it is not recommended for load-holding applications due to spool leakage. Any back pressure at the tank port adds directly to the valve setting at a 1:1 ratio. Cartridges configured with EPDM seals are compatible with phosphate ester fluids but may be damaged by petroleum-based substances. The RPECMAV model incorporates Sun's floating-style construction to reduce risks of internal binding from excessive torque or machining variations. It features a cavity T-10A series with a capacity of 25 gpm (95 L/min) and can operate at pressures up to 5000 psi (350 bar). The typical response time is around 10 ms, with maximum valve leakage specified at 2 in\u00b3/min (30 cc/min) under certain conditions. Adjustments are made via an internal hex screw, allowing for fine-tuning within its full range unless otherwise specified by special settings. The valve's robust design includes corrosion-resistant options identified by specific model code suffixes for enhanced durability in harsh environments.

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.
