The Sun Hydraulics SCCBCCN (Material Number: SCCBCCN) 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 inlet port 1 pressure surpasses the preset valve setting. It incorporates an integral check valve that allows reverse flow from port 2 to port 1, ensuring efficient operation in load-holding applications. The valve's pressure setting controls the pressure at port 1 relative to atmospheric venting. It is particularly suitable for scenarios where a drain connection is not possible, although users should be aware of potential external leakage or moisture ingress into the spring chamber over time. The SCCBCCN features Sun\u2019s floating style construction, minimizing internal part binding due to excessive installation torque or machining variations. It has a capacity of up to 15 gpm (60 L/min) and operates at a maximum pressure of 5000 psi (350 bar). The typical response time for this model is approximately 2 ms, and it exhibits a maximum valve leakage of 10 drops/min (0.7 cc/min) at reseat. The check cracking pressure stands at 40 psi (2.8 bar). Adjustments can be made with up to five clockwise turns to increase the setting, and the valve requires an installation torque between 30 - 35 lbf ft (41 - 47 Nm). Additional specifications include a valve hex size of .78 in (22.2 mm), an adjustment screw internal hex size of .532 in (4 mm), and a locknut hex size of .916 in (15 mm). The locknut torque ranges from 80 - 90 lbf in (9 - 10 Nm). This model weighs approximately .30 lb (.15 kg) and uses Viton seal kits for optimal performance.
