The Sun Hydraulics SXCBKCV (Material Number: SXCBKCV) is an atmospherically referenced, direct-acting sequence valve designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. This particular sequence valve controls pressure at port 1 relative to an atmospheric vent, making it suitable for load holding applications where a drain connection is not feasible. The design incorporates Sun's floating style construction to minimize potential binding of internal parts due to excessive installation torque or variations in cavity/cartridge machining. Key specifications include a cavity type of T-13A, with a series capacity of 15 gpm (60 L/min). Factory pressure settings are established at 2 in/min (30 cc/min), and the maximum operating pressure is rated at 5000 psi (350 bar). The typical response time for this valve is approximately 2 milliseconds. Leakage at reseat is minimal, with a maximum of 10 drops per minute (0.7 cc/min). Adjustments can be made by turning clockwise up to 4 turns to increase the setting, and the valve hex size is 7/8 in. (22.2 mm), with an installation torque requirement between 30 to 35 lbf ft (41 to 47 Nm). The adjustment screw features an internal hex size of 5/32 in. (4 mm), and the locknut has a hex size of 9/16 in. (15 mm) with a torque specification between 80 to 90 lbf in. (9 to 10 Nm). The model weight is approximately .30 lb (.15 kg). Notably, this valve should be used only when it\u2019s impossible to have a drain connection due to potential external leakage or moisture ingress into the spring chamber over time. The seal kit for this cartridge uses Viton material, identified by part number: 990010006.
