The Sun Hydraulics SXCBLCN (SXCBLCN) 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 sequence valve controls the pressure at port 1 relative to the atmospheric vent, making it suitable for load holding applications. It is crucial to note that atmospherically referenced valves should only be used where a drain connection is not possible, 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 parts binding due to excessive installation torque or cavity/cartridge machining variations. It features a cavity T-13A, Series 1 with a capacity of 15 gpm (60 L/min) and operates at a maximum pressure of 5000 psi (350 bar). The typical response time for this model is 2 ms, with maximum valve leakage at reseat being 10 drops/min (0.7 cc/min). The adjustment for increasing the setting involves 4-4/4 clockwise turns, and it has a valve hex size of 7/8 in. (22.2 mm) with an installation torque of 30 - 35 lbf ft (41 - 47 Nm). The adjustment screw requires an internal hex size of 5/32 in. (4 mm), while the locknut has a hex size of 9/16 in. (15 mm) and requires a torque of 80 - 90 lbf in. (9 - 10 Nm). Weighing approximately .30 lb (.15 kg), this model can be sealed using Viton seal kit number: 990010006.
