The Sun Hydraulics RVEBNWN (RVEBNWN) is a three-port normally closed modulating element with relief functionality, designed to provide dual operations when used with an external orifice. This hydraulic component acts as a bypass compensator, controlling priority flow into the circuit based on the external orifice's parameters. Any input flow exceeding this priority flow is diverted to tank port 2. If pressure at inlet port 1 exceeds the valve's set threshold, it functions as a standard relief valve. The compensating pressure across all ranges is maintained at 120 psi (8 bar). The performance curve illustrates system pressure against pressure differential created by the valve across the control orifice, with various curves depicting different bypass flows\u2014indicating that bypass flow determines capacity and performance, independent of control flow. The RVEBNWN model features adjustable settings using W or Y controls, which can be configured with or without special settings. Without special settings, the valve is adjustable through its full range; with them, it indicates maximum valve settings. This model fits into a T-2A cavity and offers a series 2 capacity of 20 gpm (80 L/min). It operates under a maximum pressure of 5000 psi (350 bar) and typically responds within 10 milliseconds. Maximum leakage at 110 SUS (24 cSt) is limited to 3 in\u00b3/min (50 cc/min) at 1000 psi (70 bar). For installation, it requires a torque of 45 - 50 lbf ft (61 - 68 Nm), and adjustments are made via an internal hex screw requiring specific torque settings for secure operation. The unit weighs approximately .70 lb (.30 kg) and utilizes Viton seal kits for optimal performance in hydraulic systems.

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.
