The Sun Hydraulics SXCBLBN (SXCBLBN) is an atmospherically referenced, direct-acting sequence valve designed to supply a secondary circuit with flow once the inlet port 1 pressure surpasses the valve setting. This sequence valve is particularly suitable for load holding applications and should only be used where a drain connection is not feasible. It features Sun's floating style construction, which minimizes the potential for internal parts binding due to excessive installation torque or cavity/cartridge machining variations. The valve has a capacity of 15 gpm (60 L/min) and operates at a maximum pressure of 5000 psi (350 bar). The factory pressure settings are established at a flow rate of 2 in\u00b3/min (30 cc/min), with a typical response time of 2 milliseconds. The maximum valve leakage at reseat is specified as 10 drops/min (0.7 cc/min). The design includes several specific characteristics such as an adjustment mechanism that requires approximately 4 turns clockwise to increase the setting, a valve hex size of 7/8 in. (22.2 mm), and an installation torque range of 30 - 35 lbf ft (41 - 47 Nm). The adjustment screw has an internal hex size of 5/32 in. (4 mm), while the locknut hex size is set at 9/16 in. (15 mm) with a torque specification of 80 - 90 lbf in. (9 - 10 Nm). Weighing .30 lb (.15 kg), this model also incorporates Viton seal kits, ensuring durability and performance reliability in various conditions. Note that atmospherically referenced valves may leak externally or allow moisture ingress into the spring chamber over time, with fluid passage into this chamber estimated at approximately one drop per every 4000 cycles.
