The Sun Hydraulics SCEBLDV (SCEBLDV) is an atmospherically referenced, direct-acting sequence valve with a reverse flow check, designed to supply a secondary circuit with flow once the inlet port pressure surpasses the valve setting. It features an integral check valve that allows reverse flow from port 2 to port 1. This sequence valve is particularly suitable for load-holding applications and should be used where a drain connection is not feasible. However, users should be aware that these valves may leak externally or allow moisture into the spring chamber over time. The valve design incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. The SCEBLDV fits into a T-5A cavity and has a series 2 capacity of up to 30 gpm (120 L/min). It operates at a maximum pressure of 5000 psi (350 bar) with typical response times around 2 ms. The valve exhibits minimal leakage at reseat, with a maximum of 10 drops per minute (0.7 cc/min). The check cracking pressure is set at 25 psi (1.7 bar), and adjustments can be made via the screw, which requires five full clockwise turns to increase the setting. Installation specifics include a hex size of 1-1/8 inches (28.6 mm) and an installation torque range between 45 - 50 lbf ft (61 - 68 Nm). The locknut hex size is 9/16 inches (15 mm), with a torque requirement of 80 - 90 lbf in (9 - 10 Nm). The model weighs approximately .60 lb (.30 kg) and utilizes Viton seal kits for reliable performance under various conditions.
