The Sun Hydraulics RVESKNV (RVESKNV) is a ventable, pilot-operated, balanced poppet relief cartridge designed for precise pressure regulation in hydraulic systems. This normally closed valve opens to the tank port when the inlet pressure reaches the preset level, effectively throttling flow to maintain desired pressure levels. The valve features a vent port that allows for remote control by other pilot or two-way valves, enhancing its versatility in various applications. Known for its accuracy and low pressure rise versus flow, the RVESKNV operates smoothly and quietly while being moderately fast. The internal modulating mechanism makes it resistant to cavitation issues such as noise and manifold erosion. This relief cartridge is suitable for load-holding applications, provided any valving on the vent port is zero-leak. It can handle maximum pressure at port 2, making it ideal for use in cross-port relief circuits. A remote pilot relief on the vent port can control the valve below its own setting. The design ensures reliability even with fluctuating oil temperatures and contamination levels, thanks to a 150-micron stainless steel screen protecting the main stage orifice. The RVESKNV's construction minimizes binding risks due to excessive installation torque or cavity machining variations. It has a capacity of 25 gpm (95 L/min) and can operate at pressures up to 5000 psi (350 bar). With a typical response time of 2 ms and maximum leakage at reseat of 10 drops/min (0.7 cc/min), this valve is both efficient and dependable. Installation requires specific torque settings and hex sizes for adjustment screws and locknuts, ensuring secure integration into hydraulic systems.
