The Sun Hydraulics SXCBLDN (SXCBLDN) is a direct-acting sequence valve designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. This atmospherically referenced valve is ideal for load-holding applications, especially where a drain connection is not feasible. However, users should note that over time, these valves may experience minor external leakage or allow moisture into the spring chamber, with approximately 0.07 cc of fluid entering every 4000 cycles. The SXCBLDN features Sun's floating style construction to reduce the risk of internal binding due to installation torque or machining variations. This model fits into a T-13A cavity and has a capacity of 15 gpm (60 L/min). It operates at a maximum pressure of 5000 psi (350 bar) with typical response times around 2 ms. The valve's leakage rate at reseat is minimal, at about 10 drops per minute (0.7 cc/min). Adjustments are made via an internal hex screw, requiring up to 44 clockwise turns to increase settings, and it includes specific torque requirements for installation and locknut adjustment. The SXCBLDN weighs approximately 0.30 lb (0.15 kg) and uses Viton seals in its cartridge design. Its robust construction makes it suitable for demanding hydraulic systems where precise pressure control is essential without compromising on reliability or performance over time.
