The Sun Hydraulics RPESLWV (Material Number: RPESLWV) is a pilot-operated, balanced-poppet relief cartridge valve designed for precise pressure regulation in hydraulic systems. This normally closed valve opens to tank port 2 when the inlet port 1 pressure reaches the set level, effectively throttling flow to maintain consistent pressure. Its design ensures smooth, quiet operation with minimal pressure rise relative to flow. The internal modulation within the cartridge minimizes issues such as cavitation-induced noise and manifold erosion. It is capable of handling maximum pressure at port 2, making it suitable for cross-port relief circuits and load-holding applications. The valve's performance remains stable despite variations in oil temperature and contamination levels. It features a main stage orifice protected by a 150-micron stainless steel screen and incorporates Sun's floating style construction to reduce risks of internal binding due to installation torque or machining variations. Back pressure on the tank port directly affects the valve setting at a 1:1 ratio. Adjustment options include W and Y controls, which can be specified with or without special settings; without special settings, the valve is adjustable throughout its full range. The RPESLWV has a cavity size of T-10A and series capacity of 25 gpm (95 L/min), with maximum operating pressure up to 5000 psi (350 bar). It offers a typical response time of 7 ms and has minimal leakage at standard oil viscosity. Installation requires specific torque values for both the valve body and adjustment components, ensuring secure placement within hydraulic systems. The model weighs approximately .30 lb (.15 kg) and utilizes Viton seals for optimal performance in demanding environments.
