The Sun Hydraulics COFCXAV (COFCXAV) is a high-performance pilot-to-close check cartridge valve designed for hydraulic applications requiring reliable, controlled flow. This valve features a nominal pilot ratio of 1.8:1, enabling it to close against a pressure of 1800 psi (125 bar) at port 1 when the pilot port pressure is 1000 psi (70 bar). It is specifically engineered to allow flow from port 1 to port 2 while securely blocking any reverse flow from port 2 to port 1 under all conditions. The COFCXAV incorporates Sun\u2019s floating style construction which significantly reduces the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This design enhancement ensures consistent performance and longevity of the valve even under rigorous operational conditions. The valve operates with a maximum capacity of 40 gpm (160 L/min) and can handle a maximum operating pressure up to 5000 psi (350 bar). It also has minimal leakage specifications, with a maximum valve leakage rate of only one drop per minute at an oil viscosity of 110 SUS (24 cSt). This model utilizes a T2A cavity and belongs to the Series 2 line. The physical attributes include a hex size of 1-1/8 inches (28.6 mm) and an installation torque between 45 \u201350 lbf ft (61 \u201368 Nm), with the entire unit weighing approximately .50 lb (0.25 kg). The COFCXAV is equipped with Viton seals for enhanced durability and chemical resistance, making it suitable for various hydraulic systems where precision and reliability are paramount.
