The Sun Hydraulics RVBBLWN (RVBBLWN) is a three-port normally closed modulating element designed to provide dual functionality when paired with an external orifice. This component acts primarily as a bypass compensator, regulating a priority flow into the hydraulic circuit based on the specifications of the external orifice. Any input flow exceeding this priority level is redirected to the tank via port 2. Additionally, if pressure at inlet port 1 surpasses the valve's pre-set threshold, it functions as a standard relief valve. With a compensating pressure set at 50 psi (3.5 bar) for all ranges, this valve's performance is depicted through curves that illustrate system pressure against pressure differential across the control orifice. The capacity and overall performance are influenced by bypass flow rather than control flow. Key specifications include a cavity T-163A series with a capacity of 5 gpm (20 L/min) and maximum operating pressure of up to 5000 psi (350 bar). The typical response time is around 10 milliseconds, and maximum leakage at 110 SUS (24 cSt) is recorded at 2 in\u00b3/min (30 cc/min). Adjustment settings allow for increased pressure with up to five clockwise turns, while installation torque ranges from 20 to 25 lbf ft (27 to 33 Nm). The valve features an internal hex adjustment screw size of 5/32 inches (4 mm) and a locknut hex size of 9/16 inches (15 mm), requiring torque between 80 to 90 lbf in (9 to 10 Nm). Weighing approximately .30 lb (.15 kg), it uses Viton seal kits for enhanced durability and compatibility with various hydraulic fluids.
