The Sun Hydraulics RPIEKDV (RPIEKDV) is a fast-acting, pilot-operated, balanced piston relief cartridge designed to protect hydraulic components from pressure transients. These normally closed, pressure-limiting valves quickly open and close, prioritizing speed over smoothness. When the inlet port 1 reaches the valve's preset pressure level, it begins to open towards tank port 2, throttling flow to control pressure rise. The valve exhibits low pressure rise versus flow characteristics and is known for its rapid response time of approximately 2 milliseconds. It features a main stage orifice shielded by a 150-micron stainless steel screen and is unsuitable for load-holding applications due to potential spool leakage. This cartridge is interchangeable with other two-port relief cartridges, maintaining the same flow path and cavity for equivalent frame sizes. It can handle maximum pressure at port 2, making it suitable for cross-port relief circuits; however, users should consider spool leakage in these setups. The back pressure on tank port 2 affects the valve setting directly at a 1:1 ratio. Sun's floating style construction minimizes internal part binding risks due to excessive installation torque or machining variations within the cavity/cartridge. The RPIEKDV has a capacity of up to 100 gpm (380 L/min) with factory pressure settings established at 4 gpm (15 L/min). It can operate under maximum pressures of up to 5000 psi (350 bar) and has a maximum valve leakage rate of approximately 4 in\u00b3/min at specific conditions. Installation requires a torque range between 150-160 lbf ft (203-217 Nm), with adjustment facilitated through an internal hex screw and secured by a locknut with specified torque requirements. The model weighs approximately 1.20 lb (0.55 kg) and includes an available Viton seal kit option for maintenance or replacement needs.

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.
