The Sun Hydraulics SCCBLEN (SCCBLEN) is an atmospherically referenced, direct-acting sequence valve equipped with a reverse flow check valve. This component is designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting, while the integral check valve facilitates reverse flow from port 2 to port 1. It controls pressure at port 1 relative to atmospheric venting, making it suitable for load holding applications where a drain connection is not feasible. The valve features Sun's floating style construction to prevent internal parts from binding due to installation torque or machining variations. It has a capacity of 15 gpm (60 L/min) and operates at a maximum pressure of 5000 psi (350 bar). The response time is typically 2 ms, and it allows for maximum valve leakage at reseat of up to 10 drops/min (0.7 cc/min). The check cracking pressure is set at 40 psi (2.8 bar). For adjustments, there are five clockwise turns available to increase the setting, with specific torque requirements for installation and adjustment components. The model weighs approximately .30 lb (.15 kg) and includes a Viton seal kit option for enhanced durability.
