The Sun Hydraulics SCEACEN (SCEACEN) is a direct-acting sequence valve designed to manage the flow in hydraulic systems efficiently. This valve is equipped with a reverse flow check, allowing it to supply a secondary circuit with flow once the inlet port 1 pressure surpasses the set threshold. It also features an integral check valve that facilitates reverse flow from port 2 back to port 1. The pressure setting controls the pressure at port 1 relative to the drain port 3, which must be connected to maintain proper function and prevent malfunction due to seal weepage. The sequence valve can handle pressures up to 5000 psi (350 bar) and is suitable for load-holding applications. The SCEACEN model incorporates Sun's floating style construction, minimizing internal binding risks due to installation torque or machining variations. It offers a capacity of up to 30 gpm (120 L/min) and features a maximum operating pressure of 5000 psi (350 bar). The response time for this valve is typically around 2 milliseconds, with a maximum leakage rate at reseat of 10 drops/minute (0.7 cc/min). The check cracking pressure stands at 25 psi (1.7 bar), and adjustments can be made via an internal hex screw with five full clockwise turns required for increasing settings. Installation specifics include a valve 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 torque of 80-90 lbf-in (9-10 Nm). Weighing in at just .60 lb (.30 kg), this model is compatible with Viton seals, ensuring durability under various operational conditions. This versatile component is interchangeable within its series due to standardized cavity dimensions and flow paths, making it an excellent choice for various hydraulic applications requiring precise control and reliability.
