While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Sun Hydraulics directly.***
The Sun Hydraulics RPECKAN (Material Number: RPECKAN) is a pilot-operated, balanced-piston relief cartridge valve designed for precise pressure regulation. This normally closed valve activates when the inlet port pressure reaches the set threshold, opening to the tank port and regulating flow to maintain desired pressure levels. Renowned for its accuracy and low pressure rise versus flow, this valve operates smoothly and quietly with moderate speed. The RPECKAN is interchangeable with other 2-port relief cartridges of the same frame size, making it versatile for various applications. It can handle maximum pressure at port 2 and is suitable for cross-port relief circuits, though users should consider spool leakage in such setups. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring durability. However, due to spool leakage, it is not recommended for load-holding applications. This cartridge valve features corrosion-resistant options identified by model code suffixes AP or LH for external stainless steel or zinc-nickel plated components respectively. The design incorporates Sun's floating style construction to minimize internal binding from installation torque or machining variations. The valve has a capacity of 25 gpm (95 L/min) and operates at a maximum pressure of 5000 psi (350 bar). It typically responds within 10 milliseconds and has minimal leakage at specified conditions. Adjustments can be made through W or Y controls across its full range unless a special setting is specified as the maximum setting. Cartridges with EPDM seals are suitable for phosphate ester fluid systems but are incompatible with petroleum-based fluids which can damage the seals. Installation requires specific torque settings and hex sizes as detailed in the product specifications.

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.
