The Sun Hydraulics SXCBCBN (Material Number: SXCBCBN) is an atmospherically referenced, direct-acting sequence valve designed to supply a secondary circuit with flow once the pressure at inlet port 1 exceeds the valve setting. This sequence valve controls the pressure at port 1 relative to the atmospheric vent, making it suitable for use in load holding applications where a drain connection is not possible. The valve incorporates Sun's floating style construction, minimizing the risk of internal parts binding due to excessive installation torque or machining variations. With a cavity size of T-13A and a capacity of 15 gpm (60 L/min), it features factory pressure settings established at 2 in/min (30 cc/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). The typical response time is 2 ms, and it exhibits maximum valve leakage at reseat of 10 drops/min (0.7 cc/min). Adjustments are made by turning clockwise up to four turns to increase the setting, with specific torque requirements for installation and locknut adjustments. The model weighs approximately .30 lb (0.15 kg) and comes with a Viton seal kit available under part number 990010006. It is important to note that atmospherically referenced valves may leak externally or allow moisture into the spring chamber over time, with about one drop (0.07 cc) of fluid passing into the vented spring chamber every 4000 cycles.
