The Sun Hydraulics SCEBCBV (SCEBCBV) is an atmospherically referenced, direct-acting sequence valve with reverse flow check designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. This model features an integral check valve allowing reverse flow from port 2 to port 1. It is particularly suitable for load holding applications where drain connections are impractical, although users should be aware that over time, these valves may leak externally or allow moisture into the spring chamber. Performance specifications include a capacity of 30 gpm (120 L/min) and a maximum operating pressure of 5000 psi (350 bar). The valve exhibits a typical response time of 2 ms and maintains a maximum leakage rate of 10 drops/min (0.7 cc/min) at reseat. The check cracking pressure is set at 25 psi (1.7 bar), and adjustments can be made via clockwise turns to increase settings, with up to five turns available. The valve's hex size measures 1 1/8 in. (28.6 mm), requiring an installation torque between 45 - 50 lbf ft (61 - 68 Nm). Additional specifications include an adjustment screw internal hex size of 5/32 in. (4 mm), locknut hex size of 9/16 in. (15 mm), and locknut torque ranging from 80 - 90 lbf in. (9 -10 Nm). Weighing .60 lb (.30 kg), this model incorporates Sun's floating style construction to minimize binding risks due to excessive torque or machining variations within cavity/cartridge installations. A Viton seal kit for this cartridge is available under part number: 990203006.
