The Sun Hydraulics RVIBKCN (RVIBKCN) is a versatile three-port normally closed modulating element with integrated relief functionality, designed for efficient fluid management in hydraulic systems. When combined with an external orifice, this component acts as a bypass compensator, prioritizing circuit flow based on the external orifice's specifications. Any input flow that exceeds this priority flow is redirected to tank port 2. Additionally, if the inlet pressure at port 1 surpasses the valve setting, it functions as a standard relief valve. The compensating pressure across all ranges is set at 90 psi (6 bar), and its performance curve illustrates how system pressure affects the pressure differential across the control orifice. Importantly, the bypass flow determines the capacity and performance of this valve; control flow does not influence it. This model is configured with EPDM seals, making it suitable for systems utilizing phosphate ester fluids while being incompatible with petroleum-based substances. It features a T19A cavity from Series 4 and supports a maximum capacity of 80 gpm (320 L/min). The factory establishes pressure settings at 4 gpm (15 L/min), and it can endure a maximum operating pressure of 5000 psi (350 bar). The typical response time is about 10 milliseconds, with maximum valve leakage rated at 5 in\u00b3/min (80 cc/min) at specific conditions. For installation, the RVIBKCN requires a torque range between 350 to 375 lbf ft (474 to 508 Nm) and features adjustment capabilities through clockwise turns for setting increases. This model weighs approximately 3.10 lb (1.40 kg) and includes specific dimensions for hex sizes and locknut torque requirements for secure installations.

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.
