The Sun Hydraulics SXCBCWV (SXCBCWV) is an atmospherically referenced, direct-acting sequence valve designed to supply a secondary circuit with flow once the pressure at the inlet port exceeds the valve setting. This sequence valve controls the pressure at port 1 relative to atmospheric vent, making it suitable for load holding applications. It is essential to note that atmospherically referenced valves are recommended only in scenarios where a drain connection is not feasible, as they may leak externally or allow moisture into the spring chamber over time. The valve incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations. This model has a capacity of 15 gpm (60 L/min) and can operate at a maximum pressure of 5000 psi (350 bar). The factory pressure settings are established at 2 in/min (30 cc/min), with a typical response time of 2 milliseconds. Maximum valve leakage at reseat is limited to 10 drops per minute (0.7 cc/min). For adjustment, it requires approximately four clockwise turns to increase the setting, and its installation torque ranges from 30 to 35 lbf ft (41 to 47 Nm). The valve hex size is 7/8 in. (22.2 mm), and it weighs .30 lb (.15 kg). Additionally, it includes an adjustment screw with an internal hex size of 5/32 in. (4 mm) and a locknut hex size of 9/16 in. (15 mm), with a locknut torque specification of 80 to 90 lbf in. (9 to 10 Nm). The seal kit for this cartridge uses Viton material, identified by part number 990010006.
