The Sun Hydraulics RVEBNCV (Material Number: RVEBNCV) is a three-port normally closed modulating element with relief that serves dual functions when paired with an external orifice. This component acts as a bypass compensator, regulating priority flow into a circuit based on the external orifice's specifications, and diverts any excess input flow to tank port 2. If the pressure at inlet port 1 exceeds the valve's set point, 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 on the X-axis and the pressure differential across the control orifice on the Y-axis, with various curves representing different bypass flows. The valve\u2019s capacity and performance are determined by this bypass flow; control flow does not influence it. For adjustable settings, W and Y controls can be fine-tuned throughout their entire range unless a special setting is specified, which denotes the valve's maximum setting. It features a T-2A cavity, Series 2 capacity of 20 gpm (80 L/min), with factory settings established at 4 gpm (15 L/min). It operates under a maximum pressure of 5000 psi (350 bar) with typical response times of 10 ms. Leakage is minimal at 3 in\u00b3/min at 110 SUS (24 cSt) under 1000 psi (70 bar). Adjustment requires up to five clockwise turns to increase settings, with specific installation requirements such as a valve hex size of 1-1/8 inches and installation torque between 45-50 lbf ft (61-68 Nm). The unit weighs approximately .70 lb (.30 kg) and uses Viton seals for durability 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.
