The Sun Hydraulics RVGBCDN (RVGBCDN) is a versatile hydraulic valve designed for precise flow control and pressure regulation. This three-port, normally closed modulating element with relief functionality serves dual purposes when used in conjunction with an external orifice. Primarily, it acts as a bypass compensator, managing priority flow into the circuit based on the external orifice's settings. Any input flow that exceeds this priority is redirected to tank port 2. Additionally, if the inlet port 1 pressure surpasses the pre-set valve threshold, it functions as a conventional relief valve. The RVGBCDN model features a compensating pressure of 120 psi (8 bar) across all ranges and its performance curves illustrate system pressure against the pressure differential created across the control orifice. The valve's capacity and performance are dictated by bypass flow, independent of control flow factors. It has a series 3 cavity with a capacity of 40 gpm (160 L/min), supporting a maximum operating pressure of 5000 psi (350 bar). Typical response time is around 10 milliseconds, and maximum leakage at 110 SUS (24 cSt) is rated at 4 in\u00b3/min (65 cc/min) at 1000 psi (70 bar). For adjustments, increasing the setting requires approximately 5-5/8 clockwise turns. The installation demands specific torques: valve installation torque ranges between 150 to 160 lbf\u00b7ft (203 to 217 Nm), while the locknut requires torque between 80 to 90 lbf\u00b7in (9 to 10 Nm). The RVGBCDN model weighs approximately 1.60 lb (0.70 kg) and comes with Viton cartridge seals for optimal durability and performance under varying conditions.
