The Sun Hydraulics CODCXDN (CODCXDN) is a high-performance, pilot-to-close check cartridge valve designed for hydraulic applications requiring reliable flow control. This valve features a nominal pilot ratio of 1.8:1, meaning it can close against higher pressures at port 1 when the appropriate pressure is applied at the pilot port. Specifically, a pressure of 1000 psi at the pilot port can close the valve against a pressure of 1800 psi at port 1. The valve ensures that flow is allowed from port 1 to port 2 while completely blocking reverse flow from port 2 to port 1 under any conditions. Incorporating Sun\u2019s floating style construction, the CODCXDN minimizes internal parts binding, enhancing durability and performance consistency by accommodating potential installation torque excesses and variations in cavity/cartridge machining. The valve operates with a maximum capacity of 20 gpm (80 L/min) and can withstand maximum operating pressures up to 5000 psi (350 bar). It features minimal leakage with a maximum rate of one drop per minute at an oil viscosity of 110 SUS (24 cSt). The physical specifications include a hex size of 7/8 inch (22.2 mm) and an installation torque requirement between 30 - 35 lbf ft (41 - 47 Nm). Weighing only .30 lb (0.15 kg), this valve is compact yet robust enough for demanding applications. It also supports Viton seal kits for enhanced chemical resistance and durability under various operational conditions. The CODCXDN is essential for systems requiring precise hydraulic flow control where reverse flow prevention is critical, ensuring operational safety and efficiency.
