The Sun Hydraulics SCGACEV (Material Number: SCGACEV) is a direct-acting sequence valve with a reverse-flow check, designed to supply a secondary circuit with flow once the inlet port 1 pressure surpasses the valve setting. This model includes an integral check valve to facilitate reverse flow from port 2 sequence to port 1 inlet. The pressure setting of the sequence valve regulates the pressure at port 1 relative to that at the drain port 3. All three-port sequence cartridges are interchangeable, maintaining consistent flow paths and cavity sizes for a given frame size. It is crucial to connect port 3 drain to preserve a pressure reference in the control chamber, as blocking it may lead to malfunction due to reciprocating seal weepage. The SCGACEV is suitable for load-holding applications and employs Sun's floating style construction, reducing the risk of internal part binding from excessive installation torque or cavity/cartridge machining variations. It features a maximum operating pressure of 5000 psi (350 bar) and a capacity of 60 gpm (240 L/min). The factory-established pressure settings are set at 2 in/min (30 cc/min), with response times typically around 2 ms. The maximum valve leakage at reseat is limited to 10 drops/min (0.7 cc/min), and its check cracking pressure stands at 25 psi (1.7 bar). For adjustments, the valve requires five clockwise turns to increase settings, with specific torque requirements for installation and locknut adjustments. The model weighs approximately 1.50 lb (0.70 kg) and utilizes Viton seals for durability and performance in hydraulic systems.
