The Sun Hydraulics RVIBKAN (Material Number: RVIBKAN) is a versatile three-port normally closed modulating element with relief, designed to perform dual functions when paired with an external orifice. This component acts as a bypass compensator, regulating priority flow into the circuit based on the external orifice, while redirecting excess input flow to tank port 2. Additionally, if the 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 maintained at 90 psi (6 bar), ensuring consistent performance across various applications. The valve's performance curve illustrates system pressure on the X-axis and the pressure differential across the control orifice on the Y-axis. These curves are indicative of different bypass flows, as determined by subtracting control flow from pump flow. Notably, this valve's capacity and performance are dictated by bypass flow rather than control flow. Cartridges fitted with EPDM seals are specifically intended for phosphate ester fluid systems and should not be exposed to petroleum-based substances to prevent seal damage. Key specifications include a cavity size of T-19A Series 4, a capacity of 80 gpm (320 L/min), and a maximum operating pressure of 5000 psi (350 bar). The typical response time is approximately 10 ms, with maximum valve leakage at 110 SUS (24 cSt) being limited to 5 in\u00b3/min (80 cc/min) at 1000 psi (70 bar). Adjustment involves up to 5.5 clockwise turns to increase settings, with specific torque requirements for installation and locknut adjustments. The model weighs in at 3.10 lb (1.40 kg) and utilizes Viton seal kits for optimal performance under specified conditions.

Three-port normally closed modulating elements with relief provide two functions when combined with an external orifice. The mainstage is a bypass compensator that controls a priority flow into the circuit, determined by the external orifice. Input flow in excess of the priority flow is bypassed to tank (port 2). If the inlet (port 1) pressure rises to the valve setting, the valve operates as a normal relief valve.
- Compensating pressure for all ranges is 90 psi (6 bar).
- Explanation of the performance curve: The X axis is system pressure. The Y axis shows the pressure differential that the valve creates across the control orifice. The curves represent various bypass flows (pump flow minus control flow). The capacity and performance of this valve is determined by the bypass flow, control flow is not a factor.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
