The Sun Hydraulics RVESCWV (Material Number: RVESCWV) is a ventable, pilot-operated, balanced poppet relief cartridge designed to function as a normally closed pressure regulating valve. When the inlet port pressure reaches the valve's set point, it begins to open to the tank port, throttling flow to maintain the desired pressure. This model features a vent port for remote control capabilities using other pilot or two-way valves. It is characterized by its accuracy, low-pressure rise versus flow, smooth and quiet operation, and moderate speed. The internal modulation of the cartridge makes it resistant to issues like cavitation-induced noise and manifold erosion. This relief cartridge is suitable for load-holding applications provided that any valving on the vent port is zero leak and can handle maximum pressures at port 2, making it ideal for cross-port relief circuits. A remote pilot relief on the vent port allows control below its own setting. The valve's performance remains stable despite variations in oil temperature or contamination levels due to its floating style construction that reduces binding risks from excessive installation torque or machining variations. With a capacity of 25 gpm (95 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve incorporates a main stage orifice protected by a 150-micron stainless steel screen. The back pressure on tank port 2 adds directly to the valve setting at a 1:1 ratio. Installation requires specific torques for both the valve and locknut, ensuring secure assembly. The RVESCWV model weighs 1.60 lb (0.70 kg) and uses Viton seals for reliable sealing performance in various hydraulic systems.
