The Sun Hydraulics SCGACCN (SCGACCN) is a direct-acting sequence valve equipped with a reverse flow check, designed to supply a secondary circuit with flow once the inlet port 1 pressure surpasses the valve setting. This model integrates an internal check valve allowing reverse flow from port 2 to port 1. It is crucial for load-holding applications due to its capability to manage pressure at port 1 relative to the drain port 3, which should not exceed 5000 psi (350 bar). The SCGACCN features Sun's floating style construction, minimizing internal part binding risks from excessive installation torque or machining variations. It fits into Cavity T-17A and operates efficiently at a capacity of 60 gpm (240 L/min), with factory pressure settings established at a minimum of 2 in/min (30 cc/min). The maximum operating pressure is set at 5000 psi (350 bar), and it offers a typical response time of 2 ms. The valve exhibits minimal leakage at reseat, approximately 10 drops/min (0.7 cc/min), and has a check cracking pressure of 25 psi (1.7 bar). Adjustments can be made using the internal hex screw, requiring up to five and a half clockwise turns to increase settings, with specific torque requirements for installation and locknut adjustments. This model weighs approximately 1.50 lb (0.70 kg) and includes seal kit options such as Viton: 990017006 for enhanced performance under various conditions.
