The Sun Hydraulics SCCBCAN (SCCBCAN) is an atmospherically referenced, direct-acting sequence valve with a reverse-flow check designed to supply a secondary circuit with flow once the inlet pressure at port 1 exceeds the valve setting. This model incorporates 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 not feasible. However, being atmospherically referenced, it may experience external leakage or moisture ingress over time, with approximately one drop (0.07 cc) of fluid entering the spring chamber every 4000 cycles. The valve features Sun\u2019s floating style construction to minimize internal binding due to excessive torque or machining variations. The SCCBCAN has a cavity T-13A, Series 1 capacity of 15 gpm (60 L/min) and operates at a maximum pressure of 5000 psi (350 bar). It typically responds within 2 milliseconds and has a maximum valve leakage at reseat of 10 drops/min (0.7 cc/min). The check cracking pressure is set at 40 psi (2.8 bar), and adjustments can be made using the internal hex screw, requiring approximately five clockwise turns to increase settings. Installation requires a torque of 30 \u2013 35 lbf ft (41 \u2013 47 Nm), with specific hex sizes for various adjustments: valve hex size at 7/8 in. (22.2 mm), adjustment screw internal hex size at 5/32 in. (4 mm), and locknut hex size at 9/16 in. (15 mm) with a torque of 80 \u2013 90 lbf in. (9 \u2013 10 Nm). The model weighs approximately .30 lb (.15 kg) and uses Viton seals under seal kit number: 990010006.
