The Sun Hydraulics CODCXFN (CODCXFN) is a high-performance, pilot-to-close check cartridge valve designed for hydraulic systems. This valve allows controlled flow from port 1 to port 2 while effectively blocking any reverse flow from port 2 to port 1, ensuring operational security and efficiency. The valve features a nominal pilot ratio of 1.8:1, meaning that a pressure of 1000 psi at the pilot port will close the valve against a pressure of 1800 psi at port 1. This feature is crucial for applications requiring precise control over hydraulic flow and pressure. The CODCXFN is built with Sun Hydraulics' floating style construction which minimizes potential internal part binding that can occur due to excessive installation torque or variations in cavity/cartridge machining. This design enhances the reliability and longevity of the valve under varied operational conditions. The maximum operating pressure for this model is rated at 5000 psi, with a maximum capacity of 20 gpm (80 L/min), making it suitable for high-pressure applications. Key specifications include a maximum valve leakage of one drop per minute at an oil viscosity of 110 SUS (24 cSt), and it requires an installation torque between 30-35 lbf ft (41-47 Nm). The valve's hex size is 7/8 in (22.2 mm), and it weighs approximately .30 lb (0.15 kg). For maintenance, a Viton seal kit compatible with this model is available under part number: 990011006. Overall, the Sun Hydraulics CODCXFN check cartridge offers robust performance for hydraulic systems requiring reliable non-return functionality coupled with precise control over flow and pressure parameters.
