The Sun Hydraulics SXCBKWV (SXCBKWV) 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's preset level. This sequence valve regulates pressure at port 1 relative to an atmospheric vent, making it suitable for load holding applications where a drain connection is not feasible. However, users should be aware that over time, these valves might leak externally or allow moisture into the spring chamber, with approximately one drop (0.07 cc) of fluid entering the vented spring chamber every 4,000 cycles. The valve features Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations in cavity/cartridge setups. Key specifications include a cavity size of T-13A and a series 1 capacity of 15 gpm (60 L/min), with factory pressure settings established at 2 in/min (30 cc/min). The maximum operating pressure is rated at 5,000 psi (350 bar), and it has a typical response time of 2 ms. The maximum valve leakage upon reseat is approximately 10 drops per minute (0.7 cc/min). The adjustment mechanism allows for an increase in setting with up to four clockwise turns, and installation requires a torque between 30 to 35 lbf ft (41 to 47 Nm). The model weighs approximately .30 lb (.15 kg) and includes a Viton seal kit under cartridge number 990010006.
