The Sun Hydraulics RVEBUDN (RVEBUDN) is a versatile three-port normally closed modulating element with relief capabilities, designed to provide dual functions when used in conjunction with an external orifice. This component acts as a bypass compensator, regulating priority flow into a circuit based on the external orifice's specifications. Any input flow exceeding this priority flow is redirected to tank port 2. Additionally, if the pressure at inlet port 1 surpasses the valve's set threshold, it functions as a standard relief valve. The compensating pressure for all ranges is maintained at 120 psi (8 bar). Performance curves illustrate that while system pressure is plotted on the X axis, the Y axis indicates the pressure differential created across the control orifice by the valve, with various curves representing different bypass flows. The RVEBUDN has a maximum operating pressure of 5000 psi (350 bar) and can handle a capacity of up to 20 gpm (80 L/min). It features an adjustable setting range using W and Y controls, which can be customized with or without special settings for maximum adjustment flexibility. Typical response time is approximately 10 ms, and maximum valve leakage at 110 SUS (24 cSt) is limited to 3 in\u00b3/min (1000 psi) or 50 cc/min (70 bar). Installation requires specific torque specifications: valve installation torque ranges from 45 to 50 lbf ft (61 to 68 Nm), while locknut torque should be between 80 and 90 lbf in (9 to 10 Nm). The RVEBUDN weighs .70 lb (.30 kg) and uses Viton seal kits for optimal performance.
