The Sun Hydraulics RPGEFUV (RPGEFUV) is a fast-acting, pilot-operated, balanced piston relief cartridge designed to protect hydraulic components from pressure transients. These normally closed valves are engineered for rapid opening and closing, prioritizing speed over smooth operation. When the inlet port pressure reaches the valve setting, it begins to open to the tank port, throttling flow to limit pressure rise. This model demonstrates minimal pressure rise versus flow and responds swiftly with a typical response time of 2 milliseconds. It is compatible with cross-port relief circuits but should not be used in load-holding applications due to spool leakage. The main stage orifice is safeguarded by a 150-micron stainless steel screen, ensuring reliability and longevity. The RPGEFUV model is interchangeable with other 2-port relief cartridges of the same frame size and flow path. It can accept maximum pressure at port 2 and incorporates Sun's floating style construction to reduce internal binding risks caused by installation torque or machining variations. The cartridge accommodates systems using phosphate ester fluids when equipped with EPDM seals but should avoid exposure to petroleum-based substances as they can damage these seals. Additional specifications include a capacity of 50 gpm (200 L/min), a maximum operating pressure of 5000 psi (350 bar), and a valve hex size of 1-1/8 inches (28.6 mm). Installation torque ranges from 45 to 50 lbf-ft (61 to 68 Nm), while adjustment settings require approximately five clockwise turns for increased settings. This cartridge weighs approximately .50 lb (.25 kg) and comes with an optional Viton seal kit for enhanced performance under specific conditions.

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.
- 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.
- 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.
