The Sun Hydraulics SXEACDV (SXEACDV) is a direct-acting sequence valve designed to supply a secondary circuit with flow once the pressure at inlet port 1 exceeds the valve's set pressure. This sequence valve is suitable for load-holding applications and features interchangeable 3-port cartridges, maintaining consistent flow paths and cavity compatibility for a given frame size. The valve integrates Sun's floating style construction to minimize internal part binding due to excessive installation torque or cavity machining variations. It operates with a maximum flow capacity of 30 gpm (120 L/min) and withstands operating pressures up to 5000 psi (350 bar). The response time is typically 2 milliseconds, and the maximum valve leakage at reseat is limited to 10 drops per minute (0.7 cc/min). Adjustments can be made with up to four clockwise turns to increase the setting, utilizing an internal hex size of 5/32 inches (4 mm). Installation requires a torque of 45-50 lbf ft (61-68 Nm), while the locknut torque specification is between 80-90 lbf in (9-10 Nm). The valve weighs approximately 0.60 lbs (0.30 kg) and uses Viton seals, with a designated seal kit available as part number 990202006. It\u2019s important that port 3 drain remains unblocked to maintain proper pressure reference in the control chamber; otherwise, reciprocating seal weepage may lead to malfunctioning. Pressure at port 3 should not exceed the additive limit of 5000 psi relative to the valve setting, ensuring reliable performance in hydraulic systems requiring precise pressure control and sequencing functions.
