The Sun Hydraulics RVBBKNN (RVBBKNN) is a three-port normally closed modulating element designed to provide dual functionality when paired with an external orifice. Primarily, it acts as a bypass compensator, regulating priority flow into circuits as dictated by the external orifice. Surplus input flow beyond the priority flow is redirected to tank port 2. Additionally, if the pressure at inlet port 1 surpasses the valve setting, it functions as a standard relief valve. The compensating pressure across all ranges is set at 50 psi (3.5 bar). The performance curve illustrates system pressure on the X-axis and the pressure differential created by the valve across the control orifice on the Y-axis, with various curves indicating different bypass flows. The valve's capacity and performance are contingent upon bypass flow rather than control flow. This model fits into cavity T-163A, Series 0, and has a capacity of 5 gpm (20 L/min). It can handle a maximum operating pressure of up to 5000 psi (350 bar), with a typical response time of 10 ms. Maximum leakage at 110 SUS (24 cSt) is limited to 2 in\u00b3/min (30 cc/min) under 1000 psi (70 bar). Adjustment settings can be increased with up to 5.5 clockwise turns. Installation specifications include a valve hex size of 3/4 in. (19.1 mm), installation torque between 20 - 25 lbf ft (27 - 33 Nm), an adjustment screw internal hex size of 5/32 in. (4 mm), and locknut torque between 80 - 90 lbf in. (9 -10 Nm). The model weighs approximately .30 lb (.15 kg) and utilizes Viton seal kits for optimal performance and durability in hydraulic applications requiring precise flow control and relief functionalities.
