The Sun Hydraulics SCGACBN (SCGACBN) is a direct-acting sequence valve with a reverse flow check, designed to manage the supply of a secondary circuit once the inlet port 1 pressure exceeds the valve setting. This model includes an integral check valve for reverse flow from port 2 to port 1. It features a zero pilot flow design, requiring connection of port 3 to maintain pressure reference in the control chamber, with a maximum allowable pressure of 5000 psi at this port. The SCGACBN is suitable for load holding applications and utilizes Sun's floating style construction to prevent internal parts binding due to installation or machining variations. The valve's cavity is T-17A, Series 3, with a capacity of up to 60 gpm (240 L/min), and it has factory-established pressure settings at a leakage rate of up to 10 drops/min upon reseat. The check cracking pressure is set at 25 psi (1.7 bar), with adjustment possible through five clockwise turns. The hex size for installation is 1-1/4 inches, and it requires an installation torque between 150 -160 lbf ft (203 -217 Nm). The adjustment screw has an internal hex size of 5/32 inches, while the locknut hex size is 9/16 inches, necessitating torque between 80 -90 lbf in (9 -10 Nm). Weighing approximately 1.50 lb (0.70 kg), this model also includes Viton seal kits for durability and performance under various conditions.
