The Sun Hydraulics RVEBUBN (Material Number: RVEBUBN) is a three-port normally closed modulating element with relief capabilities, designed to provide dual functions when paired with an external orifice. This valve serves as a bypass compensator, controlling priority flow into a circuit as determined by the external orifice, while any excess input flow is redirected to tank port 2. Additionally, it functions as a standard relief valve if the pressure at inlet port 1 exceeds the valve's set point. The compensating pressure for all ranges is fixed at 120 psi (8 bar). Performance curves illustrate the relationship between system pressure and the pressure differential created across the control orifice, highlighting that valve capacity and performance are influenced by bypass flow rather than control flow. The RVEBUBN model can be adjusted throughout its full range using W or Y controls unless a special maximum setting is specified. Key specifications include a cavity T-2A series design with a capacity of up to 20 gpm (80 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response time of 10 ms. Valve leakage is minimal at 3 in\u00b3/min at 1000 psi (50 cc/min at 70 bar). The adjustment mechanism allows for up to five full clockwise turns to increase settings, and installation requires specific torque values for both the valve and locknut. The unit weighs approximately .70 lb (.30 kg) and comes with a Viton seal kit (Cartridge: 990202006).
