The Sun Hydraulics RVEBJDN (RVEBJDN) is a three-port, normally closed modulating element with relief that offers dual functionality when used with an external orifice. Specifically designed as a bypass compensator, this component effectively manages priority flow into a circuit, determined by the external orifice, while redirecting any excess input flow to the tank port. In scenarios where the inlet port pressure exceeds the valve's setting, it functions as a standard relief valve. The compensating pressure for all ranges is maintained at 120 psi (8 bar). The valve's performance curve illustrates the relationship between system pressure and the pressure differential across the control orifice, with its capacity dictated by bypass flow rather than control flow. Available controls include W and Y options, which can be adjusted throughout their range unless a special setting is specified; in such cases, this setting denotes the valve's maximum adjustment limit. This model features a T-2A cavity and Series 2 capacity of 20 gpm (80 L/min), with factory pressure settings established at 4 gpm (15 L/min). It operates under a maximum pressure of 5000 psi (350 bar) and typically responds within 10 milliseconds. Leakage rates are minimal at a maximum of 3 in\u00b3/min (50 cc/min) at 110 SUS (24 cSt). For adjustments, users can increase settings with up to five clockwise turns of the adjustment screw. The valve has specific installation torque requirements and comes equipped with Viton seals for enhanced durability. Weighing just .70 lb (.30 kg), it is compact yet robust for various hydraulic applications requiring precise flow management and overpressure protection.

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 120 psi (8 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.
  • W and Y controls (where applicable) can be specified with or without a special setting. When no special setting is specified, the valve is adjustable throughout its full range using the W or Y control. When a special setting is specified, this setting represents the maximum setting of the valve.
