The Sun Hydraulics SCGALBN (SCGALBN) is a direct-acting sequence valve with a reverse-flow check, designed to supply a secondary circuit with flow once the inlet pressure exceeds the valve setting. This model incorporates an integral check valve for reverse flow from port 2 to port 1, making it suitable for load-holding applications. The pressure setting controls the pressure at port 1 relative to the drain port 3, and all three-port sequence cartridges are interchangeable. It features zero pilot flow, but requires port 3 to be connected to maintain a pressure reference; blocking this port may cause malfunction due to seal weepage. The valve supports pressures up to 5000 psi (350 bar) and utilizes Sun's floating style construction, minimizing internal binding risks from installation torque or machining variations. With a capacity of 60 gpm (240 L/min), it offers a typical response time of 2 ms and has a maximum leakage rate of 10 drops/min at reseat. The check cracking pressure is set at 25 psi (1.7 bar). Adjustments are made via an internal hex screw, with five full clockwise turns needed to increase settings. Installation requires specific torque settings: valve hex size is 1-1/4 in (31.8 mm), with an installation torque of 150\u2013160 lbf\u00b7ft (203\u2013217 Nm). The locknut hex size is 9/16 in (15 mm) with torque specifications of 80\u201390 lbf\u00b7in (9\u201310 Nm). Weighing in at approximately 1.50 lb (0.70 kg), this model includes Viton seals and offers robust performance in demanding hydraulic applications where precise control and reliability are paramount.
