The Sun Hydraulics SXEALEN (SXEALEN) is a direct-acting sequence valve designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. This valve is suitable for load-holding applications and features a zero pilot flow design, requiring the drain port 3 to be connected to maintain pressure reference in the control chamber. Blocking port 3 can lead to malfunction due to reciprocating seal weepage. The pressure at port 3 should not exceed 5000 psi (350 bar) and is directly additive to the valve setting at a 1:1 ratio. This model incorporates Sun's floating style construction, minimizing internal part binding due to installation torque or machining variations. It has a capacity of 30 gpm (120 L/min) and operates at a maximum pressure of 5000 psi (350 bar), with typical response time being approximately 2 ms. The valve allows up to 44 clockwise turns for setting adjustments, with maximum leakage at reseat being limited to 10 drops per minute. The SXEALEN model weighs .60 lb (.30 kg) and requires specific installation torques for optimal performance: valve installation torque is between 45-50 lbf ft (61-68 Nm), while locknut torque ranges from 80-90 lbf in (9-10 Nm). This sequence valve also offers physical and functional interchangeability across all three-port sequence cartridges within the same frame size, enhancing its versatility in various hydraulic systems.
