The Sun Hydraulics SCEBKEV (SCEBKEV) is an atmospherically referenced, direct-acting sequence valve with a reverse flow check, designed to manage secondary circuit flow once the inlet port 1 pressure surpasses the preset valve setting. Featuring an integral check valve, it allows reverse flow from port 2 sequence back to the port 1 inlet. This sequence valve is ideal for load-holding applications and should only be used when a drain connection is not feasible due to potential external leakage or moisture ingress into the spring chamber over time. The valve uses Sun's floating style construction to prevent internal part binding caused by excessive installation torque or machining variations. Key specifications include a cavity type of T-5A and a series capacity of 30 gpm (120 L/min). It can withstand a maximum operating pressure of 5000 psi (350 bar) and has a typical response time of 2 ms. The factory pressure settings are established at 2 in/min (30 cc/min), with maximum valve leakage at reseat being 10 drops/min (0.7 cc/min). The check cracking pressure is set at 25 psi (1.7 bar), and adjustments can be made with up to five full clockwise turns to increase the setting. The valve features a hex size of 1-1/8 inches (28.6 mm) and requires an installation torque of between 45 - 50 lbf\u00b7ft (61 - 68 Nm). Additional physical specifications include an adjustment screw internal hex size of 5/32 inches (4 mm), locknut hex size of 9/16 inches (15 mm), and locknut torque between 80 - 90 lbf\u00b7in (9 -10 Nm). The model weighs approximately .60 lb (.30 kg) and uses Viton seals, specifically seal kit number: 990203006 for cartridge maintenance.
