The Sun Hydraulics SCEACDV (SCEACDV) is a direct-acting sequence valve with an integrated reverse-flow check, designed to initiate flow to a secondary circuit once the inlet port 1 pressure surpasses the valve's preset level. This valve features an integral check valve that allows reverse flow from port 2 back to port 1. It is crucial for the drain port 3 to be connected, as blocking it could lead to valve malfunction due to seal weepage. The pressure at port 3 adds directly to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar). This component is suitable for load-holding applications and ensures functional interchangeability across all three-port sequence cartridges within a given frame size. The Sun floating style construction minimizes internal part binding due to installation torque or machining variations. The SCEACDV model offers a capacity of up to 30 gpm (120 L/min) and operates under a maximum pressure of 5000 psi (350 bar). It exhibits typical response times of about 2 milliseconds and has minimal leakage rates at reseat, measured at up to 10 drops per minute (0.7 cc/min). The check cracking pressure is set at 25 psi (1.7 bar). Adjustments can be made by turning the adjustment screw clockwise, with five full turns available for setting increases. The valve features specific installation requirements, including a hex size of 1-1/8 inches (28.6 mm) and an installation torque range of 45-50 lbf-ft (61-68 Nm). The locknut requires a hex size of 9/16 inches (15 mm) with torque settings between 80-90 lbf-in (9-10 Nm). Weighing in at .60 lb (.30 kg), this model also supports Viton seal kits for enhanced durability in various applications.
