The Sun Hydraulics SCEBKDV (SCEBKDV) is an atmospherically referenced, direct-acting sequence valve designed for precise hydraulic control applications. It features a reverse-flow check valve, allowing flow from the secondary circuit to the primary inlet once a set pressure threshold at port 1 is exceeded. This design ensures efficient load holding and pressure control by maintaining the pressure at port 1 relative to atmospheric vent conditions. The valve incorporates Sun's floating style construction, which minimizes internal binding due to installation torque or machining variations. With a cavity size of T-5A and a series 2 capacity of 30 gpm (120 L/min), this valve operates at a maximum pressure of 5000 psi (350 bar) and has a typical response time of 2 ms. It features a check cracking pressure of 25 psi (1.7 bar) and can be adjusted with up to five clockwise turns for increased settings. The SCEBKDV has specific torque requirements for installation, with a valve hex size of 1 1/8 in. (28.6 mm) and an installation torque range of 45-50 lbf ft (61-68 Nm). The adjustment screw has an internal hex size of 5/32 in. (4 mm), while the locknut hex size is 9/16 in. (15 mm), requiring a locknut torque of 80-90 lbf in. (9-10 Nm). Weighing .60 lb (.30 kg), this model includes Viton seals with part number 990203006, ensuring compatibility with various hydraulic fluids and temperature conditions while providing reliable performance over time.
