The Sun Hydraulics RPESCWV (Material Number: RPESCWV) is a pilot-operated, balanced poppet relief cartridge designed to function as a normally closed pressure regulating valve. When the inlet port 1 reaches the designated valve setting, it begins to open to tank port 2, allowing for flow throttling to maintain regulated pressure. This valve is known for its accuracy, smooth operation, quiet performance, and quick response time of approximately 7 ms. It also features a low pressure rise versus flow. The internal modulation within the cartridge makes it resistant to cavitation-related issues such as noise and manifold erosion. It can handle maximum pressure at port 2 and is suitable for cross-port relief circuits and load-holding applications. The valve's design ensures insensitivity to oil temperature fluctuations and contamination, with a main stage orifice protected by a 150-micron stainless steel screen. The back pressure on tank port 2 directly adds to the valve setting at a 1:1 ratio. This model incorporates Sun\u2019s floating style construction, reducing risks of internal parts binding due to installation torque or machining variations in cavity/cartridge interfaces. It offers adjustable settings through W and Y controls across its full range unless specified otherwise with a special setting. The RPESCWV has an operational capacity of up to 25 gpm (95 L/min) at a maximum operating pressure of 5000 psi (350 bar). Installation requires specific torques for both the valve body and locknut, ensuring secure placement within hydraulic systems. With minimal leakage rates at standard conditions and options for Viton seal kits, this cartridge is well-suited for applications demanding reliable pressure control under varying operational conditions.
