The Sun Hydraulics RVIBCCN (RVIBCCN) is a versatile three-port normally closed modulating element designed to provide dual functionality when paired with an external orifice. Primarily, it acts as a bypass compensator, regulating priority flow into a circuit as dictated by the external orifice, while any surplus input flow is directed to tank port 2. Additionally, should the pressure at inlet port 1 exceed the valve's preset level, it functions as a standard relief valve. The compensating pressure for all ranges is set at 90 psi (6 bar). The performance curve illustrates system pressure on the X-axis and the pressure differential created across the control orifice on the Y-axis, with curves indicating various bypass flows. Notably, this valve\u2019s capacity and performance are determined by bypass flow rather than control flow. The RVIBCCN is ideal for systems using phosphate ester fluids due to its EPDM seals, which are incompatible with petroleum-based products. It features a T-19A cavity and Series 4 capacity of up to 80 gpm (320 L/min), with factory pressure settings established at 4 gpm (15 L/min). The maximum operating pressure reaches up to 5000 psi (350 bar), and it boasts a typical response time of 10 ms. Maximum valve leakage at 110 SUS (24 cSt) is limited to 5 in\u00b3/min (80 cc/min) at 1000 psi (70 bar). Adjustments can be made via a screw requiring up to 5/32 in. internal hex size, with installation torque ranging from 350 - 375 lbf ft (474 - 508 Nm). The model weighs approximately 3.10 lb (1.40 kg) and utilizes Viton seal kits for cartridge maintenance.
