The Sun Hydraulics SCCBCAV (SCCBCAV) is an atmospherically referenced, direct-acting sequence valve designed for efficient control in hydraulic systems. This component is particularly suitable for load-holding applications, where it supplies a secondary circuit with flow once the pressure at inlet port 1 surpasses the valve setting. It features an integral check valve that allows reverse flow from port 2 to port 1, enhancing its versatility in complex hydraulic circuits. The valve's pressure setting controls the pressure at port 1 relative to atmospheric venting, making it ideal for scenarios where a drain connection is impractical. Constructed with Sun's floating style design, the SCCBCAV minimizes internal binding risks due to excessive installation torque or machining variations. It has a capacity of 15 gpm (60 L/min) and can withstand a maximum operating pressure of up to 5000 psi (350 bar). The typical response time is approximately 2 milliseconds, ensuring quick and reliable performance. The valve features a check cracking pressure of 40 psi (2.8 bar) and allows adjustment through clockwise turns, with specific hex sizes provided for both the adjustment screw and locknut. The SCCBCAV also incorporates a Viton seal kit option and requires specific installation torque values to ensure optimal functionality. Notably, over time, these valves may experience minor external leakage or moisture ingress into the spring chamber due to their atmospheric referencing design. Despite this, they remain robust components in applications where traditional drain connections are not feasible.
