The Sun Hydraulics SCEACBN (SCEACBN) is a direct-acting sequence valve with reverse flow check, designed to manage the flow to a secondary circuit once the inlet port pressure surpasses the valve setting. This model incorporates an integral check valve that facilitates reverse flow from port 2 back to port 1. It is essential for the pressure at port 3, which serves as a drain, to be connected and not exceed 5000 psi (350 bar), as it directly influences the valve setting. The SCEACBN is suitable for load holding applications and features interchangeable three-port sequence cartridges that maintain consistent flow paths and cavity compatibility across similar frame sizes. This model employs Sun's floating style construction, reducing the risk of internal 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). The typical response time for this valve is approximately 2 milliseconds, with a maximum leakage rate of 10 drops/minute at reseat conditions. The check cracking pressure is set at 25 psi (1.7 bar), and users can adjust settings with up to five clockwise turns. For installation, the valve requires a hex size of 1-1/8 inches (28.6 mm) and an installation torque between 45-50 lbf-ft (61-68 Nm). The adjustment screw uses an internal hex size of 5/32 inches (4 mm), while the locknut has a hex size of 9/16 inches (15 mm) with a torque range of 80-90 lbf-in (9-10 Nm). Weighing approximately .60 lb (.30 kg), this model also includes compatibility with Viton seal kits, specifically cartridge kit number 990202006.
