The Sun Hydraulics SCGACEN (SCGACEN) 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 includes an integral check valve for reverse flow from port 2 to port 1. The pressure setting 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 features a maximum operating pressure of 5000 psi (350 bar) and can handle a capacity of up to 60 gpm (240 L/min). It is suitable for load-holding applications and incorporates Sun's floating style construction, minimizing internal part binding due to excessive installation torque or machining variations. The SCGACEN model is physically and functionally interchangeable with other three-port sequence cartridges of the same frame size, sharing the same flow path and cavity. It has a response time of approximately 2 milliseconds and allows for maximum valve leakage at reseat of up to 10 drops per minute. The check cracking pressure is set at 25 psi (1.7 bar), and adjustment can be made by turning clockwise up to five turns to increase settings. The installation torque required ranges from 150 to 160 lbf-ft (203 to 217 Nm), with an internal hex size adjustment screw of 5/32 inches (4 mm). The locknut requires a torque of between 80 and 90 lbf-in (9 to 10 Nm). This model weighs approximately 1.50 lb (0.70 kg) and uses Viton seal kits under cartridge number 990017006, ensuring compatibility with various hydraulic systems while maintaining high performance standards under demanding conditions.
