The Sun Hydraulics SXCBLWV (SXCBLWV) 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 maintains pressure at port 1 relative to the atmospheric vent, making it suitable for load holding applications where a drain connection is not feasible. However, it is important to note that these valves may leak externally or allow moisture into the spring chamber over time, with approximately one drop (0.07 cc) of fluid entering the vented spring chamber every 4000 cycles. The valve incorporates Sun's floating style construction, minimizing internal part binding due to excessive installation torque or machining variations. The SXCBLWV features a T-13A cavity and series 1 capacity of up to 15 gpm (60 L/min), with factory pressure settings established at 2 in/min (30 cc/min). It can handle a maximum operating pressure of 5000 psi (350 bar) and has a typical response time of 2 ms. The maximum valve leakage at reseat is specified at 10 drops/min (0.7 cc/min). The adjustment mechanism allows for increasing the setting with 44 clockwise turns, and it includes 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), and the locknut features a hex size of 9/16 in. (15 mm) with a torque specification of 80-90 lbf in. (9-10 Nm). This model weighs approximately .30 lb (.15 kg) and utilizes Viton seal kits for cartridge sealing requirements.
