The Sun Hydraulics RVEBLDN (RVEBLDN) is a sophisticated three-port normally closed modulating element with relief functionality, designed to optimize hydraulic system performance. This component serves dual purposes when integrated with an external orifice. Primarily, it acts as a bypass compensator, regulating priority flow within the circuit as defined by the external orifice, while excess input flow is redirected to tank port 2. Additionally, the valve functions as a conventional relief valve if pressure at inlet port 1 exceeds the set threshold. The compensating pressure across all ranges is maintained at 120 psi (8 bar). The performance of this valve is clearly depicted through its performance curves, where system pressure is plotted against the pressure differential created across the control orifice. These curves illustrate various bypass flows, emphasizing that valve capacity and performance are contingent on bypass flow rather than control flow. Specifications for this model include a cavity type of T-2A and a series designation of 2, with a capacity to handle up to 20 gpm (80 L/min). It operates under a maximum pressure of 5000 psi (350 bar), with typical response times around 10 ms. The valve ensures minimal leakage at specified conditions and allows for adjustment through clockwise turns to increase settings up to 55 turns. Additional features include installation torque specifications ranging from 45 to 50 lbf ft (61 to 68 Nm), and an internal hex size for adjustment screws measuring at \\( \\frac{5}{32} \\) in. (4 mm). The model weighs approximately .70 lb (.30 kg) and comes equipped with Viton seal kit cartridge number 990202006 for optimal sealing performance.
