The Sun Hydraulics RPIECWV (RPIECWV) is a fast-acting, pilot-operated, balanced piston relief cartridge designed to protect hydraulic components from pressure transients. This normally closed, pressure-limiting valve opens rapidly to relieve excess pressure by throttling flow from the inlet port to the tank port, ensuring minimal pressure rise. Although this quick response comes at the cost of smoothness, it makes the valve highly efficient in applications requiring rapid pressure relief. The valve features low-pressure rise versus flow and can accept maximum pressure at port 2, making it suitable for cross-port relief circuits, though spool leakage should be considered in such applications. The main stage orifice is safeguarded by a 150-micron stainless steel screen. However, this model is not recommended for load-holding applications due to potential spool leakage. The RPIECWV employs Sun's floating style construction to minimize internal part binding caused by excessive installation torque or machining variations. With a capacity of up to 100 gpm (380 L/min) and a maximum operating pressure of 5000 psi (350 bar), the valve demonstrates robust performance. Its typical response time is around 2 ms with a maximum valve leakage of 4 in\u00b3/min at 1000 psi (65 cc/min at 70 bar). The adjustment mechanism allows for precise control with up to five clockwise turns needed to increase settings. Installation requires specific torque values: 150-160 lbf ft (203-217 Nm) for the valve and 80-90 lbf in (9-10 Nm) for the locknut. Weighing approximately 1.20 lb (0.55 kg), this cartridge includes a Viton seal kit option (990016006) for enhanced durability under various operational 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.
- 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.
