The Sun Hydraulics SCCBCDV (SCCBCDV) is an atmospherically referenced, direct-acting sequence valve with an integral reverse-flow check. This advanced component is designed to supply a secondary circuit with flow once the inlet port pressure surpasses the valve setting. The integral check valve facilitates reverse flow from port 2 to port 1, ensuring efficient operation in various hydraulic systems. The pressure setting of this sequence valve governs the pressure at port 1 relative to the atmospheric vent, making it especially suitable for load-holding applications where a drain connection is not feasible. However, users should be aware that atmospherically referenced valves may experience external leakage or moisture ingress over time. This valve incorporates Sun's floating style construction, minimizing internal part binding due to excessive installation torque or machining variations. It operates within a cavity T-13A and boasts a series 1 capacity of 15 gpm (60 L/min). The factory pressure settings are established at 2 in/min (30 cc/min), with a maximum operating pressure of 5000 psi (350 bar) and a typical response time of 2 ms. The maximum valve leakage at reseat is limited to 10 drops/min (0.7 cc/min), and it features a check cracking pressure of 40 psi (2.8 bar). Adjustments can be made via the adjustment screw, which requires five turns clockwise to increase the setting. The valve hex size is 7/8 in. (22.2 mm), with an installation torque range of 30 - 35 lbf ft (41 - 47 Nm). The locknut hex size is 9/16 in. (15 mm), requiring torque between 80 - 90 lbf in. (9 -10 Nm). Weighing only .30 lb (.15 kg), this model also includes a Viton seal kit for enhanced durability and performance under various operational conditions.
