The Sun Hydraulics SCCBCCV (SCCBCCV) is an atmospherically referenced, direct-acting sequence valve with a reverse-flow check feature. This valve is designed to supply a secondary circuit with flow once the pressure at inlet port 1 surpasses the set threshold. It integrates an internal check valve to facilitate reverse flow from port 2 back to port 1, effectively controlling pressure at port 1 in relation to atmospheric venting. The SCCBCCV is particularly suited for load-holding applications where it is not feasible to have a drain connection. Notably, this valve utilizes Sun's floating style construction, which helps minimize the risk of internal component binding due to excessive installation torque or machining variations in cavity or cartridge. The valve features a capacity of 15 gpm (60 L/min) and operates at a maximum pressure of 5000 psi (350 bar). It has a typical response time of 2 ms and allows for maximum leakage of 10 drops/min (0.7 cc/min) upon reseat. The check cracking pressure is set at 40 psi (2.8 bar). Users can adjust the valve setting by turning the adjustment screw clockwise up to five full turns, and it requires specific installation torque values: between 30 and 35 lbf ft (41 and 47 Nm). The seal kit for this model uses Viton material, identified by part number 990010006. While atmospherically referenced valves like this one may experience external leakage or moisture ingress over time, they are designed for scenarios where traditional drain connections are impractical. The SCCBCCV represents a robust solution for controlling hydraulic sequences in demanding applications while minimizing maintenance needs through its innovative construction design.
