The Sun Hydraulics SXEAKBV (Material Number: SXEAKBV) is a direct-acting sequence valve designed to manage flow to a secondary circuit once the pressure at the inlet port 1 exceeds the valve's preset level. This valve effectively controls the pressure at port 1 relative to the drain port 3, ensuring optimal performance in load-holding applications. Notably, it is a zero pilot flow valve, which necessitates that port 3 remains unblocked to maintain an accurate pressure reference in the control chamber. The valve setting can be adjusted with pressure at port 3 directly adding to it in a 1:1 ratio, with a maximum allowable pressure of 5000 psi (350 bar). This model incorporates Sun's floating style construction, minimizing internal component binding risks due to excessive installation torque or cavity machining variations. The SXEAKBV is suitable for use in applications requiring reliable sequence control and features interchangeable functionality with other three-port sequence cartridges of similar frame sizes. It has a cavity size of T-2A and can handle capacities up to 30 gpm (120 L/min). The factory pressure settings are established at a flow rate of 2 in\u00b3/min (30 cc/min), with a typical response time of just 2 ms. Maximum operating pressure is rated at 5000 psi (350 bar), and leakage rates are minimal, not exceeding ten drops per minute upon reseating. Installation specifications include a hex size of 1-1/8 inches (28.6 mm) and an installation torque range of 45-50 lbf-ft (61-68 Nm). The adjustment screw features an internal hex size of 5/32 inches (4 mm), while the locknut requires a torque between 80-90 lbf-in (9-10 Nm). The model weighs .60 lb (.30 kg) and comes with an optional Viton seal kit under part number 990202006 for enhanced durability and performance under various operating conditions.
