The Sun Hydraulics SCCBCBV (SCCBCBV) is an atmospherically referenced, direct-acting sequence valve with a reverse-flow check designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. This model incorporates an integral check valve to enable reverse flow from port 2 to port 1, controlling pressure at port 1 relative to atmospheric vent. It is particularly suitable for load holding applications and should only be used where a drain connection is not feasible due to potential external leakage or moisture ingress into the spring chamber over time. The valve features Sun's floating style construction, minimizing the risk of internal parts binding due to excessive installation torque or machining variations. With a capacity of 15 gpm (60 L/min) and a maximum operating pressure of 5000 psi (350 bar), this sequence valve has a typical response time of 2 ms and allows maximum leakage of 10 drops/min at reseat. The check cracking pressure is set at 40 psi (2.8 bar). Adjustment involves up to five turns clockwise to increase setting, with specific hex sizes for the valve body, adjustment screw, and locknut. Installation requires torque settings between 30-35 lbf ft (41-47 Nm) for the valve and 80-90 lbf in (9-10 Nm) for the locknut. Weighing approximately .30 lb (.15 kg), this model uses Viton seals, identified by cartridge seal kit number 990010006.
