The Sun Hydraulics RPECLAE (RPECLAE) is a pilot-operated, balanced-piston relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve opens to the tank port 2 when the inlet port 1 pressure reaches its set point, effectively throttling flow to maintain desired pressure levels. Known for its accuracy and low-pressure rise versus flow characteristics, the RPECLAE operates smoothly and quietly with moderate speed. It features a main stage orifice protected by a 150-micron stainless steel screen, ensuring durability and reliability in various applications. This relief cartridge is interchangeable with other two-port relief cartridges of the same frame size, offering flexibility in system design. It can handle maximum pressure at port 2, making it suitable for cross-port relief circuits, though spool leakage should be considered in such configurations. However, it is not recommended for load-holding applications due to potential spool leakage. The RPECLAE incorporates Sun's floating style construction to prevent internal parts from binding due to installation torque or machining variations. It has a capacity of 25 gpm (95 L/min) and can operate at pressures up to 5000 psi (350 bar). The valve's response time is typically around 10 ms, and it allows a maximum leakage of 2 in\u00b3/min at 1000 psi (30 cc/min at 70 bar). Adjustments can be made using an internal hex screw with specific torque requirements for secure installation. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are available; exposure to petroleum-based fluids should be avoided as it may damage these seals. The model weighs approximately .30 lb (0.15 kg) and includes options for corrosion-resistant components identified by suffixes AP or LH based on external material finishes.

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.
