The Sun Hydraulics SXEAKBN (SXEAKBN) is a direct-acting sequence valve designed to supply a secondary circuit with flow once the pressure at inlet port 1 surpasses the valve setting. This valve effectively controls the pressure at port 1 in relation to the pressure at drain port 3. It is part of a versatile line of 3-port sequence cartridges that are interchangeable in terms of flow path and cavity for a given frame size. Notably, although this is a zero pilot flow valve, port 3 must be connected to ensure a pressure reference in the control chamber. Blocking port 3 can lead to malfunction due to seal weepage. The pressure at port 3 adds directly to the valve setting on a 1:1 ratio and should not exceed 5000 psi (350 bar). The SXEAKBN model is suitable for load-holding applications and includes Sun's floating style construction, which reduces internal part binding risks from excessive installation torque or machining variations. It features a capacity of up to 30 gpm (120 L/min) and can withstand operating pressures up to 5000 psi (350 bar). Typical response time is approximately 2 ms, with maximum valve leakage at reseat being about 10 drops/min (0.7 cc/min). The adjustment requires four clockwise turns to increase the setting, with specific torque requirements for installation and locknut adjustments. Weighing approximately .60 lb (.30 kg), this model also offers compatibility with Viton seal kits for enhanced durability.
