The Sun Hydraulics SCCBCWV (SCCBCWV) 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 features an integral check valve that facilitates reverse flow from port 2 to port 1. It is particularly suitable for load holding applications and should be employed in situations where a drain connection is not feasible. Notably, these valves may experience external leakage or moisture ingress into the spring chamber over time, with approximately one drop (0.07 cc) of fluid entering the vented spring chamber every 4000 cycles. The SCCBCWV incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations. It fits into a Cavity T-13A and has a series 1 capacity of 15 gpm (60 L/min). Factory pressure settings are established at 2 in/min (30 cc/min), with a maximum operating pressure of 5000 psi (350 bar) and typical response time of 2 ms. The maximum valve leakage at reseat is rated at 10 drops/min (0.7 cc/min), and it features a check cracking pressure of 40 psi (2.8 bar). Adjustment is achieved through clockwise turns, with up to five turns available for increasing settings. The valve hex size measures 7/8 in. (22.2 mm), and the installation torque ranges between 30 - 35 lbf ft (41 - 47 Nm). The adjustment screw has an internal hex size of 5/32 in. (4 mm), while the locknut hex size is 9/16 in. (15 mm) with a torque range of 80 - 90 lbf in. (9 -10 Nm). The model weighs approximately .30 lb (.15 kg), and it uses Viton seal kits for maintenance purposes.
