The Sun Hydraulics RPGETWV (Material Number: RPGETWV) is a fast-acting, pilot-operated, balanced piston relief cartridge designed to protect hydraulic components from pressure transients. This valve is normally closed and functions as a pressure-limiting device, opening quickly to relieve excess pressure when the inlet port reaches the pre-set level. It then throttles flow to the tank port to maintain controlled pressure levels. The valve features a low-pressure rise versus flow and offers rapid response times, making it suitable for applications where speed is prioritized over smoothness of operation. The RPGETWV can handle maximum pressures at port 2 and is applicable in cross-port relief circuits, though users should be mindful of spool leakage in such setups. This cartridge incorporates Sun's floating style construction to minimize binding risks due to installation or machining variations. It includes a 150-micron stainless steel screen protecting the main stage orifice and accepts back pressure on the tank port directly additive to the valve setting at a 1:1 ratio. While not suitable for load-holding applications due to potential leakage, it is highly adaptable for systems using phosphate ester fluids when configured with EPDM seals. The valve's installation requirements include specific torque settings and hex sizes for assembly components such as the adjustment screw and locknut. The RPGETWV has a capacity of up to 50 gpm (200 L/min) and operates at pressures reaching 5000 psi (350 bar). Its typical response time is approximately 2 milliseconds, with minimal leakage rates under specified conditions. This cartridge can be adjusted through clockwise turns of its screw mechanism, offering precise control over its pressure settings within established tolerances.

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.
