The Sun Hydraulics RVCBLAV (RVCBLAV) is a three-port normally closed modulating element with relief functionality, designed to provide dual operations when paired with an external orifice. It functions primarily as a bypass compensator, controlling priority flow into the circuit based on the external orifice specifications. Any input flow exceeding the priority flow is redirected to tank port 2. Additionally, if the pressure at inlet port 1 surpasses the valve setting, it operates as a standard relief valve. The compensating pressure varies across different ranges: 45 psi (3 bar) for range A, 30 psi (2 bar) for range B, and 100 psi (7 bar) for range C. The performance curve indicates that system pressure is plotted on the X-axis while the Y-axis represents the pressure differential created by the valve across the control orifice; various curves depict different bypass flows, with capacity and performance determined by bypass flow rather than control flow. This model fits a T-11A cavity and belongs to Series 1 with a capacity of up to 10 gpm (40 L/min). It can handle a maximum operating pressure of 5000 psi (350 bar), with typical response times around 10 milliseconds. Maximum valve leakage at 110 SUS (24 cSt) is rated at 2 in\u00b3/min under 1000 psi (30 cc/min under 70 bar). The adjustment mechanism requires approximately five clockwise turns to increase settings, with specific torque requirements for installation and adjustments: valve installation torque is between 30 and 35 lbf-ft (41 to 47 Nm), adjustment screw internal hex size is ^5\u204432 in. (4 mm), locknut hex size is ^9\u204416 in. (15 mm), and locknut torque ranges from 80 to 90 lbf-in. (9 to 10 Nm). The model weighs approximately .40 lb (.20 kg) and uses Viton seal kits for cartridge sealing.
