The Sun Hydraulics RVGBCBN (RVGBCBN) is a versatile three-port, normally closed modulating element with relief function. This component is designed to provide dual functionality when used with an external orifice. It acts as a bypass compensator, controlling priority flow into the circuit based on the external orifice's specifications. Any input flow exceeding this priority flow is redirected to tank port 2. Additionally, if the pressure at inlet port 1 surpasses the valve setting, it functions as a traditional relief valve. The compensating pressure across all ranges is maintained at 120 psi (8 bar). The performance curve illustrates system pressure on the X-axis and pressure differential across the control orifice on the Y-axis, highlighting various bypass flows where pump flow exceeds control flow. This valve's capacity and performance are influenced by bypass flow rather than control flow. The RVGBCBN features a T-17A cavity series with a capacity of 40 gpm (160 L/min) and can handle a maximum operating pressure of up to 5000 psi (350 bar). It has a typical response time of 10 ms and exhibits minimal leakage at 110 SUS (24 cSt), capped at 4 in\u00b3/min (65 cc/min) at 1000 psi (70 bar). The valve's setting can be adjusted by turning clockwise up to five times, requiring an installation torque between 150-160 lbf-ft (203-217 Nm). The adjustment screw has an internal hex size of 5/32 in. (4 mm), while the locknut hex size is 9/16 in. (15 mm), with a locknut torque specification of 80-90 lbf-in. (9-10 Nm). The model weighs approximately 1.60 lb (0.70 kg) and uses a Viton seal kit identified by cartridge number 990017006.
