The Sun Hydraulics SCEBKCV (SCEBKCV) 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 exceeds the valve setting. It features an integral check valve for reverse flow from port 2 to port 1. This sequence valve is particularly suitable for load-holding applications and should be used in scenarios where a drain connection is not feasible. Notably, these valves might experience external leakage or moisture ingress into the spring chamber over time, with approximately one drop (0.07 cc) of fluid entering the vented spring chamber every 4000 cycles. The valve incorporates Sun's floating style construction to minimize internal binding due to excessive installation torque or machining variations. Key specifications include a cavity T-5A series 2 capacity of 30 gpm (120 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response time of 2 ms. The maximum valve leakage at reseat is 10 drops/min (0.7 cc/min), with a check cracking pressure of 25 psi (1.7 bar). The adjustment requires approximately five clockwise turns to increase the setting, with specific torque requirements for installation and adjustment components: valve hex size of 1-1/8 in. (28.6 mm), installation torque of 45-50 lbf-ft (61-68 Nm), adjustment screw internal hex size of 5/32 in. (4 mm), locknut hex size of 9/16 in. (15 mm), and locknut torque of 80-90 lbf-in (9-10 Nm). The model weight is .60 lb (.30 kg) and it uses a Viton seal kit cartridge identified by part number 990203006.
