The Sun Hydraulics SCEBLWV (SCEBLWV) 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 1 pressure surpasses the valve setting. This valve features an integral check valve allowing reverse flow from port 2 to port 1. It is particularly suitable for load holding applications where a drain connection is impractical. Over time, these valves may experience external leakage or moisture ingress into the spring chamber, with approximately one drop (0.07 cc) of fluid entering the vented spring chamber every 4000 cycles. The valve employs Sun's floating style construction to reduce internal binding risks due to excessive installation torque or cavity machining variations. Key specifications include a cavity type T-5A, series 2 with a capacity of 30 gpm (120 L/min), and it operates at a maximum pressure of 5000 psi (350 bar). The typical response time is approximately 2 ms, and maximum valve leakage at reseat is limited to 10 drops/min (0.7 cc/min). The check cracking pressure stands at 25 psi (1.7 bar). Adjustment involves up to five clockwise turns to increase settings, with specific torque requirements for installation and adjustment components: Valve hex size is 1-1/8 in. (28.6 mm) with an installation torque of 45-50 lbf ft (61-68 Nm), adjustment screw internal hex size is 5/32 in. (4 mm), locknut hex size is 9/16 in. (15 mm), and locknut torque ranges from 80-90 lbf in. (9-10 Nm). The model weighs approximately .60 lb (.30 kg), and it comes with a Viton seal kit cartridge identified by part number 990203006.
