The Sun Hydraulics RPESCWN (RPESCWN) is a pilot-operated, balanced-poppet relief cartridge valve designed to regulate pressure in hydraulic systems. This normally closed valve opens when the inlet port pressure reaches the set level, directing flow to the tank port to maintain stable pressure. Known for its accuracy, smooth operation, and low noise levels, this valve effectively minimizes cavitation issues such as noise and manifold erosion. It can handle maximum pressure at port 2 and is suitable for cross-port relief circuits. The valve's performance remains consistent despite fluctuations in oil temperature or contamination levels, thanks to its robust design featuring a 150-micron stainless steel screen protecting the main stage orifice. Ideal for load-holding applications, the RPESCWN ensures that back pressure on the tank port directly influences the valve setting at a 1:1 ratio. The W and Y controls allow for full-range adjustability unless a specific setting is applied, which then defines the maximum setting. The floating style construction reduces risks of internal parts binding due to excessive torque or machining variations during installation. This model fits into a T-10A cavity with a capacity of 25 gpm (95 L/min) and can operate at pressures up to 5000 psi (350 bar). It offers a typical response time of 7 ms and minimal leakage of 10 drops/minute at standard viscosity conditions. Installation requires specific torque settings for both the valve and locknut components. With a compact weight of .30 lb (.15 kg), it includes Viton seals for durability in various applications.
