The Sun Hydraulics COFCXFV (COFCXFV) is a high-performance hydraulic check valve designed for precise fluid control in various applications. This spring-biased closed, pilot-to-close check cartridge features a nominal pilot ratio of 1.8:1, facilitating robust operation under demanding conditions. The valve ensures unidirectional flow from port 1 to port 2 while completely blocking reverse flow from port 2 to port 1 under any circumstances. It operates with a maximum capacity of 40 gpm (160 L/min) and can handle a maximum operating pressure of up to 5000 psi (350 bar). The COFCXFV valve is engineered with Sun\u2019s floating style construction which minimizes internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining, ensuring reliable and consistent performance. The design specifications include a valve hex size of 1-1/8 in. (28.6 mm) and an installation torque range of 45 - 50 lbf\u00b7ft (61 - 68 Nm). The model weighs approximately 0.50 lb (0.25 kg), and uses Viton seals for enhanced durability and resistance against high temperatures and chemicals. This valve's functionality is critical in systems where precise hydraulic flow control is necessary, especially where safety or performance could be compromised by unwanted reverse flow or leakage. Its meticulous design ensures minimal leakage at high pressures, with a maximum valve leakage rate specified at about one drop per minute at 110 SUS (24 cSt). This makes the COFCXFV an essential component for advanced hydraulic circuits demanding high reliability and efficiency.
