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 RPEEFCV (RPEEFCV) is a fast-acting, pilot-operated, balanced piston relief cartridge designed to protect hydraulic components from pressure transients. This normally closed valve opens quickly to limit pressure rise when the inlet port pressure reaches the valve setting, redirecting flow to the tank port. It features a low pressure rise versus flow and operates with exceptional speed. While it can handle maximum pressure at port 2 and is suitable for cross-port relief circuits, users should be mindful of spool leakage in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen. This relief cartridge is not appropriate for load holding due to potential spool leakage, and any back pressure on the tank port directly adds to the valve setting at a 1:1 ratio. The RPEEFCV model's design allows for physical and functional interchangeability with other 2-port relief cartridges of the same frame size, except pilot reliefs. It utilizes Sun's floating style construction to reduce internal part binding risks due to installation torque or machining variations. Key specifications include a Series 1 capacity of 25 gpm (95 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 2 ms, and maximum valve leakage of 2 in\u00b3/min at 110 SUS (24 cSt). The valve features an adjustable range controlled by W or Y controls unless specified otherwise for special settings. Installation requires a torque of 30 - 35 lbf ft (41 - 47 Nm) with adjustment screw and locknut hex sizes being ^5/32 in (4 mm) and ^9/16 in (15 mm) respectively. The model weighs .30 lb (.15 kg) and uses Viton seal kits identified as part number 990010006.

Fast-acting, pilot-operated, balanced piston relief cartridges are normally closed, pressure-limiting valves used to protect hydraulics components from pressure transients. Fast opening and closing is gained at the expense of smoothness. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank (port 2), throttling flow to limit the pressure rise. These valves have low pressure rise vs. flow and are very 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).
  • 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.
  • 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.
