The Sun Hydraulics SCGACBV (SCGACBV) is a direct-acting sequence valve with an integrated reverse flow check designed to manage secondary circuit flow once the inlet port pressure exceeds the valve's set threshold. This model includes a built-in check valve that facilitates reverse flow from port 2 to port 1, enhancing its versatility in hydraulic systems. The valve's setting controls the pressure at port 1 relative to the drain port 3, and it is essential for port 3 to remain unblocked to prevent malfunction due to reciprocating seal weepage. The SCGACBV can handle a maximum operating pressure of 5000 psi (350 bar) and is suitable for load-holding applications due to its robust design features. It employs Sun's floating style construction, minimizing risks of internal binding from installation torque or machining variations. This sequence valve boasts a zero pilot flow design and requires connection of port 3 drain for maintaining accurate pressure references within the control chamber. Its performance is characterized by a response time of approximately 2 milliseconds and minimal leakage at reseat with a maximum of 10 drops per minute. The valve supports a capacity of up to 60 gpm (240 L/min) with factory pressure settings established at an inflow rate of 30 cc/min. Additionally, it features adjustable settings via an internal hex screw, allowing for precise calibration with up to five clockwise turns needed to increase the setting. The SCGACBV's construction includes Viton seals and zinc-nickel plating for enhanced corrosion resistance, making it reliable in various demanding environments.
