The Sun Hydraulics SCCBLWV (SCCBLWV) is an atmospherically referenced, direct-acting sequence valve equipped with a reverse-flow check. This valve is designed to supply a secondary circuit with flow once the inlet port 1 pressure surpasses the valve setting. It features an integral check valve that allows reverse flow from port 2 to port 1. The pressure setting of this sequence valve regulates the pressure at port 1 relative to the atmospheric vent, making it suitable for load holding applications where a drain connection is not feasible. The design incorporates Sun's floating style construction, which minimizes internal part binding due to excessive installation torque or cavity/cartridge machining variations. The SCCBLWV has a capacity of 15 gpm (60 L/min) and can operate at a maximum pressure of 5000 psi (350 bar). It responds typically within 2 milliseconds and has maximum valve leakage at reseat of 10 drops/min (0.7 cc/min). The check cracking pressure is set at 40 psi (2.8 bar), and the adjustment can be increased by turning clockwise up to five full turns. Installation requires specific torque settings: the valve hex size is 7/8 in. (22.2 mm), with an installation torque between 30 and 35 lbf ft (41 - 47 Nm). The adjustment screw internal hex size is 5/32 in. (4 mm), while the locknut hex size is 9/16 in. (15 mm), requiring a locknut torque of between 80 and 90 lbf in. (9 -10 Nm). The model weighs approximately .30 lb (.15 kg) and uses Viton seal kits available under part number: 990010006.
