The Sun Hydraulics SXEALBN (SXEALBN) is a direct-acting sequence valve designed to manage flow in secondary circuits once the inlet port pressure exceeds the valve setting. It regulates the pressure at port 1 relative to port 3, and all three-port sequence cartridges are interchangeable in terms of flow path and cavity for a given frame size. Despite being a zero pilot flow valve, it requires a connection at port 3 to maintain pressure reference; blocking this port can lead to malfunction due to seal weepage. The pressure at port 3 adds directly to the valve setting on a 1:1 ratio, with a maximum limit of 5000 psi (350 bar). This model is ideal for load-holding applications and features Sun's floating style construction, which minimizes binding risks from excessive torque or machining variations. The SXEALBN has a capacity of 30 gpm (120 L/min) and operates up to 5000 psi (350 bar), with typical response times around 2 ms. Valve leakage at reseat is minimal, capped at 10 drops/min (0.7 cc/min). The adjustment mechanism allows for four clockwise turns to increase settings, with specific torques required for installation, adjustment screw, and locknut. Weighing approximately 0.60 lb (0.30 kg), it\u2019s compatible with Viton seal kits for enhanced durability in various hydraulic systems.
