The Sun Hydraulics SXCBKEV (SXCBKEV) is an atmospherically referenced, direct-acting sequence valve designed to supply a secondary circuit with flow once the inlet port 1 pressure surpasses the valve's set threshold. This model is particularly suitable for load-holding applications where a drain connection is not feasible. However, users should note that atmospherically referenced valves can potentially leak externally or allow moisture ingress into the spring chamber over time, with approximately 0.07 cc of fluid entering the vented spring chamber every 4000 cycles. The SXCBKEV features Sun\u2019s floating style construction, reducing the likelihood of internal component binding due to excessive installation torque or machining variations in cavities and cartridges. This valve fits a T-13A cavity and has a series 1 capacity of 15 gpm (60 L/min). It operates at a maximum pressure of 5000 psi (350 bar) and provides typical response times of about 2 milliseconds. The maximum valve leakage at reseat is limited to 10 drops per minute (0.7 cc/min). To increase the pressure setting, users can turn the adjustment screw clockwise up to four full turns. The valve hex size measures at 7/8 inch (22.2 mm), requiring an installation torque between 30 to 35 lbf ft (41 to 47 Nm). The adjustment screw has an internal hex size of 5/32 inch (4 mm), while the locknut hex size is set at 9/16 inch (15 mm) with a torque specification of 80 to 90 lbf in (9 to 10 Nm). Weighing approximately .30 lb (.15 kg), this model includes a Viton seal kit for reliable performance in various applications.
