The Sun Hydraulics SXCBCEV (SXCBCEV) is an atmospherically referenced, direct-acting sequence valve designed to supply a secondary circuit with flow once the pressure at inlet port 1 surpasses the valve setting. This sequence valve regulates pressure at port 1 relative to the atmospheric vent, making it suitable for load holding applications. It is important to note that atmospherically referenced valves should only be used where a drain connection is impossible, as they may leak externally or allow moisture into the spring chamber over time. Specifically, approximately 0.07 cc of fluid will enter the vented spring chamber every 4,000 cycles. The valve incorporates Sun\u2019s floating style construction to minimize internal part binding due to excessive installation torque or cavity/cartridge machining variations. The SXCBCEV has a capacity of 15 gpm (60 L/min) and can withstand a maximum operating pressure of 5,000 psi (350 bar). Its typical response time is approximately 2 ms, and it features a maximum valve leakage at reseat of 10 drops/min (0.7 cc/min). The adjustment mechanism allows for pressure setting increases with up to four clockwise turns. Installation requires a torque of 30-35 lbf ft (41-47 Nm), while the locknut requires a torque of 80-90 lbf in (9-10 Nm). The valve also includes an internal hex adjustment screw and comes with Viton seal kit number 990010006. With its robust design and precise control capabilities, this sequence valve is ideal for applications requiring reliable pressure management in hydraulic systems without direct drain connections.
