The Sun Hydraulics SXEAKCN (Material Number: SXEAKCN) is a direct-acting sequence valve designed to supply a secondary circuit with flow once the inlet port 1 pressure surpasses the valve setting. This model is part of Sun Hydraulics' versatile line of 3-port sequence cartridges, which are physically and functionally interchangeable, meaning they share the same flow path and cavity for a given frame size. The SXEAKCN features zero pilot flow; however, port 3 must be connected to maintain a pressure reference in the control chamber, as blocking it may result in valve malfunction due to reciprocating seal weepage. The valve can handle pressures at port 3 up to 5000 psi (350 bar), which directly adds to the valve setting at a 1:1 ratio. This product is particularly suitable for load-holding applications and incorporates Sun's floating style construction, minimizing the risk of internal parts binding from excessive installation torque or machining variations. It has a capacity of 30 gpm (120 L/min) and operates optimally at pressures up to 5000 psi (350 bar). The typical response time for this model is approximately 2 ms, with maximum valve leakage at reseat being about 10 drops/min (0.7 cc/min). For adjustments, the SXEAKCN requires four clockwise turns to increase its setting, with specific torque requirements for installation and adjustment components: valve hex size is 1-1/8 in. (28.6 mm), installation torque ranges from 45-50 lbf-ft (61-68 Nm), adjustment screw internal hex size is 5/32 in. (4 mm), locknut hex size is 9/16 in. (15 mm), and locknut torque ranges from 80-90 lbf-in (9-10 Nm). The model weighs approximately .60 lb (.30 kg) and uses Viton seal kits identified as part number 990202006.
