The Sun Hydraulics RVGBKAN (RVGBKAN) is a three-port, normally closed modulating element with relief capabilities, designed to provide dual functions when paired with an external orifice. This valve operates as a bypass compensator, managing priority flow into a circuit based on the external orifice's specifications. Any input flow exceeding the priority flow is redirected to tank port 2. Additionally, if pressure at inlet port 1 exceeds the valve's set threshold, it functions as a standard relief valve. The compensating pressure for all ranges is set at 120 psi (8 bar). The performance curve illustrates how system pressure affects the pressure differential across the control orifice, highlighting that capacity and performance are determined by bypass flow rather than control flow. Key specifications include a cavity size of T-17A, series 3 capacity of 40 gpm (160 L/min), and maximum operating pressure of 5000 psi (350 bar). The response time is typically around 10 ms. Maximum valve leakage at 110 SUS (24 cSt) is measured at 4 in\u00b3/min (65 cc/min) under 1000 psi (70 bar). Adjustments can be made with up to five and a half clockwise turns to increase settings, while installation requires torque between 150-160 lbf\u00b7ft (203-217 Nm). The valve features a hex size of 1\u00bc inches (31.8 mm) for installation and an internal hex size of ^5/32 inches (4 mm) for adjustment screws. Locknut adjustments require torque between 80-90 lbf\u00b7in (9-10 Nm). The model weighs approximately 1.60 lb (0.70 kg) and utilizes a Viton seal kit with cartridge number 990017006 for optimal performance and durability in hydraulic systems.
