The Sun Hydraulics SXCBKBV (SXCBKBV) is an atmospherically referenced, direct-acting sequence valve designed to supply a secondary circuit with flow once the inlet port pressure 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 these valves should only be used in scenarios where a drain connection is impossible, as they may leak externally or allow moisture into the spring chamber over time. The Sun floating style construction minimizes internal part binding due to excessive installation torque or cavity/cartridge machining variations. The SXCBKBV model features a capacity of 15 gpm (60 L/min) and can operate at a maximum pressure of 5000 psi (350 bar). Its typical response time is 2 ms, and it has a maximum valve leakage at reseat of 10 drops/min (0.7 cc/min). The valve allows for adjustment through 4.4 clockwise turns to increase the setting. Installation requires a torque of 30 - 35 lbf ft (41 - 47 Nm), and it includes specific hex sizes for both the valve and locknut adjustments. Weighing in at .30 lb (0.15 kg), this model also comes with a Viton seal kit cartridge, part number 990010006. This product incorporates advanced design features such as Sun's floating style screw-in cartridge, which enhances reliability by reducing potential issues related to installation and machining variations. The SXCBKBV sequence valve is ideal for applications where maintaining controlled pressure in secondary circuits is critical, especially when traditional drain connections are not feasible.
