The Sun Hydraulics RVIBLCN (Material Number: RVIBLCN) is a three-port normally closed modulating element with relief capabilities, designed for integration with an external orifice. This component serves dual functions by acting as a bypass compensator, which manages priority flow into a circuit based on the external orifice, while redirecting excess input flow to the tank port 2. Additionally, when the inlet port 1 pressure reaches the valve's set threshold, it functions as a standard relief valve. The compensating pressure across all ranges is maintained at 90 psi (6 bar). The performance curve of this valve is characterized by system pressure on the X-axis and the pressure differential across the control orifice on the Y-axis, with various curves depicting different bypass flows. Notably, this valve's capacity and performance are determined by its bypass flow rather than control flow. The cartridge can be equipped with EPDM seals for compatibility with phosphate ester fluids; however, these seals are not suitable for use with petroleum-based fluids due to potential damage. Key specifications include a cavity size of T-19A, series 4 capacity of 80 gpm (320 L/min), and a maximum operating pressure of 5000 psi (350 bar). The typical response time is around 10 ms, and maximum valve leakage at 110 SUS (24 cSt) is rated at 5 in\u00b3/min (80 cc/min) at 1000 psi (70 bar). Adjustment involves up to five clockwise turns to increase settings, utilizing internal hex sizes of 5/32 in. (4 mm) for adjustment screws and locknut hex sizes of 9/16 in. (15 mm), with respective torque requirements specified. The model weighs approximately 3.10 lb (1.40 kg) and can be fitted with Viton seal kits if necessary.
