The Sun Hydraulics RVEBCBN (RVEBCBN) is a sophisticated hydraulic component designed to provide dual functionality when paired with an external orifice. This three-port, normally closed modulating element primarily acts as a bypass compensator, managing priority flow into a circuit while redirecting excess input flow to the tank port. Additionally, it functions as a relief valve if the pressure at the inlet port surpasses the preset level. The RVEBCBN maintains a compensating pressure of 120 psi (8 bar) across all ranges and offers adjustable settings through W or Y controls. Its performance is illustrated by pressure differential curves, which are influenced by bypass flow rather than control flow. The valve operates effectively at a maximum capacity of 20 gpm (80 L/min) and can withstand pressures up to 5000 psi (350 bar). With a typical response time of 10 milliseconds and minimal leakage, this component ensures efficient hydraulic system operation. Installation requires specific torque values for both the valve and its locknut, ensuring secure placement. The RVEBCBN is compatible with Viton seal kits and weighs approximately 0.70 lb (0.30 kg).

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.
