The Sun Hydraulics RVEBCDN (RVEBCDN) is a versatile three-port normally closed modulating element with relief functionality designed to optimize hydraulic systems. This component integrates two essential functions when used in conjunction with an external orifice. Primarily, it operates as a bypass compensator, managing a priority flow into the circuit as dictated by the external orifice, while any input flow exceeding this priority is redirected to tank port 2. Additionally, if the pressure at inlet port 1 surpasses the valve's set threshold, it seamlessly transitions into functioning as a standard relief valve. The compensating pressure for all ranges is maintained at 120 psi (8 bar). The performance curve's X-axis represents system pressure, whereas the Y-axis indicates the pressure differential across the control orifice created by the valve. Various curves depict different bypass flows, which are calculated as pump flow minus control flow; notably, the valve's capacity and performance are contingent on this bypass flow rather than control flow. The RVEBCDN model features adjustable W and Y controls that can be customized with or without a special setting\u2014adjustable throughout its range unless specified otherwise. Key specifications include a cavity type of T-2A Series 2 with a capacity of 20 gpm (80 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response time of 10 ms. Maximum valve leakage at 110 SUS (24 cSt) is quantified at 3 in\u00b3/min (50 cc/min) under 1000 psi (70 bar). The adjustment mechanism requires up to five clockwise turns to increase settings, and it includes specific torque requirements for installation and locknut adjustments. The model weighs approximately .70 lb (.30 kg) and uses Viton seal kits for maintenance purposes.
