The Sun Hydraulics SXEALDV (SXEALDV) is a direct-acting sequence valve designed to manage fluid flow in hydraulic systems by supplying a secondary circuit with flow once the inlet port 1 pressure surpasses the valve setting. This sequence valve maintains control over the pressure at port 1 relative to the drain port 3, ensuring efficient operation in load-holding applications. The valve features a zero pilot flow design, requiring port 3 to be connected for maintaining pressure reference in the control chamber. Blocking port 3 can lead to malfunction due to reciprocating seal weepage. The maximum allowable pressure at port 3 is additive to the valve setting at a 1:1 ratio and must not exceed 5000 psi (350 bar). Engineered with Sun's floating style construction, this valve minimizes internal binding risks due to excessive installation torque or machining variations. It fits within the T-2A cavity and is interchangeable with other three-port sequence cartridges of similar frame size, offering a consistent flow path and capacity of up to 30 gpm (120 L/min). Factory settings are established at a leakage rate of up to 10 drops/minute (0.7 cc/min) upon reseat, with response times typically around 2 ms. The SXEALDV supports adjustments via an internal hex screw and locknut system, allowing for fine-tuning with up to four clockwise turns required for increased settings. The unit's installation torque ranges between 45-50 lbf-ft (61-68 Nm), while its locknut torque specification is set between 80-90 lbf-in (9-10 Nm). Weighing approximately .60 lb (.30 kg), it incorporates Viton seals and offers robust performance suitable for various hydraulic applications requiring precise sequencing capabilities.
