The Sun Hydraulics RPICKAN (Material Number: RPICKAN) is a pilot-operated, balanced piston relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve opens to tank port 2 when the inlet port 1 pressure reaches the preset level, allowing it to throttle flow and maintain consistent pressure. Known for its accuracy and smooth operation, the RPICKAN valve features low pressure rise versus flow and moderate response speed. It can handle a maximum operating pressure of 5000 psi (350 bar) and has a typical response time of 10 ms. The valve's main stage orifice is protected by a robust 150-micron stainless steel screen, ensuring durability and reliability in demanding applications. This relief cartridge is suitable for use in cross-port relief circuits, though spool leakage should be considered in such configurations. It is not recommended for load-holding applications due to potential leakage issues. The back pressure on tank port 2 adds directly to the valve setting at a 1:1 ratio, which should be factored into system design. The RPICKAN model incorporates Sun's floating style construction to minimize internal binding from installation torque or machining variations. For environments requiring corrosion resistance, the valve can be configured with external stainless steel components (suffix AP) or zinc-nickel plating (suffix LH). Additionally, cartridges with EPDM seals are available for systems using phosphate ester fluids; however, these seals are incompatible with petroleum-based fluids. The valve\u2019s settings can be adjusted using W or Y controls unless a specific maximum setting is specified. With its interchangeable design across similar frame sizes and cavities, this Sun Hydraulics relief cartridge offers versatility and reliability for various hydraulic applications.

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.

  • 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.
  • All 2-port relief cartridges (except pilot reliefs) are physically and functionally interchangeable (same flow path, same cavity for a given frame size).
  • 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.
