The Sun Hydraulics RVGSCAV (RVGSCAV) is a ventable, pilot-operated, balanced-poppet relief cartridge designed for precise pressure regulation in hydraulic systems. This valve remains normally closed and begins to open when the inlet port 1 pressure reaches the preset level, directing flow to tank port 2 to maintain regulated pressure. A vent port, port 3, allows for remote control via other pilot or two-way valves. Known for its accuracy and low-pressure rise versus flow characteristics, this valve operates smoothly and quietly with moderate speed. Its design ensures immunity to cavitation-related issues like noise and manifold erosion. This cartridge is ideal for load-holding applications provided that any valving on the vent port is zero-leak. It can handle maximum pressure at port 2, making it suitable for cross-port relief circuits. The valve's setting can be controlled remotely via a pilot relief on the vent port. It exhibits relative insensitivity to variations in oil temperature and contamination, with a main stage orifice protected by a 150-micron stainless steel screen. Back pressure on tank port 2 adds directly to the valve setting at a 1:1 ratio. The Sun floating style construction minimizes risks of internal part binding due to excessive installation torque or machining variations in cavities/cartridges. With a capacity of up to 50 gpm (200 L/min) and maximum operating pressure of 5000 psi (350 bar), this valve ensures reliable performance with minimal leakage at reseat conditions. The cartridge features an adjustment mechanism allowing up to five clockwise turns to increase settings, providing flexibility in various applications. The RVGSCAV model is equipped with EPDM seals suitable for systems using phosphate ester fluids but should avoid exposure to petroleum-based substances which may damage the seals.
