The Sun Hydraulics SXCBLEV (Material Number: SXCBLEV) 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 particularly suitable for load holding applications. It is important to note that atmospherically referenced valves should only be used in situations where a drain connection is not possible, as they may leak externally or allow moisture into the spring chamber over time. The valve features Sun's floating style construction to minimize internal binding due to installation torque or machining variations. The SXCBLEV valve fits into a Cavity T-13A and has a series 1 capacity of 15 gpm (60 L/min). Factory pressure settings are established at a flow rate of 2 in\u00b3/min (30 cc/min), with a maximum operating pressure of 5000 psi (350 bar). The typical response time is 2 milliseconds, and maximum valve leakage at reseat is rated at 10 drops/min (0.7 cc/min). The adjustment mechanism allows for up to four clockwise turns to increase the setting, with specific torque requirements for installation and adjustment components. The valve's hex size is 7/8 inch (22.2 mm), requiring an installation torque of 30-35 lbf\u00b7ft (41-47 Nm). The adjustment screw has an internal hex size of 5/32 inch (4 mm), and the locknut requires a torque of 80-90 lbf\u00b7in (9-10 Nm). The model weighs approximately .30 lb (.15 kg) and uses a Viton seal kit with part number 990010006.
