The Sun Hydraulics SCGACDN (SCGACDN) is a direct-acting sequence valve with reverse flow check, designed to supply a secondary circuit with flow once the inlet port pressure exceeds the valve setting. It features an integral check valve for reverse flow from port 2 to port 1. This sequence valve controls the pressure at port 1 relative to the drain port 3, which must be connected to maintain a pressure reference in the control chamber. The valve is suitable for load holding applications and incorporates Sun's floating style construction to minimize binding due to installation torque or machining variations. It has a capacity of 60 gpm (240 L/min) and operates at a maximum pressure of 5000 psi (350 bar). The response time is typically 2 ms, and it has a maximum leakage rate of 10 drops/min (0.7 cc/min) at reseat. The check cracking pressure is set at 25 psi (1.7 bar), and adjustment can be made through clockwise turns, up to five and a half turns, to increase settings. The valve requires specific installation torque values: the valve hex size is 1-1/4 inches (31.8 mm), installation torque is between 150 - 160 lbf ft (203 - 217 Nm), adjustment screw internal hex size is 5/32 inches (4 mm), locknut hex size is 9/16 inches (15 mm), and locknut torque ranges from 80 - 90 lbf in (9 - 10 Nm). The model weighs approximately 1.50 lb (0.70 kg) and uses Viton seal kits for optimal performance in various applications.

Direct-acting sequence valves with reverse-flow check will supply a secondary circuit with flow once the pressure at the inlet (port 1) has exceeded the valve setting. Additionally, these valves incorporate an integral check valve to provide reverse flow from port 2 (sequence) to port 1 (inlet). The pressure setting of a sequence valve controls the pressure at port 1 relative to the pressure at the drain (port 3).
- All 3 port sequence cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size).
- Although this is a zero pilot flow valve, port 3 (drain) must be connected to maintain a pressure reference in the control chamber. If port 3 is blocked, reciprocating seal weepage will cause the valve to malfunction.
- Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).
- Suitable for use in load holding applications.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
