The Sun Hydraulics CNFEXAN (CNFEXAN) is a pilot-to-close check cartridge valve designed for hydraulic systems requiring reliable, directional flow control. This model offers a spring-biased closed configuration that ensures flow is allowed from port 1 to port 2 while restricting it from port 2 to port 1. The valve features a nominal pilot ratio of 1.8:1, meaning that it requires a higher pressure at the pilot port relative to the pressure at port 1 to remain closed. This characteristic makes the valve suitable for applications where precise control over flow direction and pressure is critical. Constructed with hardened steel seats, the CNFEXAN valve exhibits exceptional wear characteristics and contamination tolerance, enhancing its durability and reliability in tough working conditions. The specified bypass orifice diameter can be customized according to customer requirements within an allowable range, providing flexibility in application and installation. Additionally, this model incorporates Sun\u2019s floating style construction which minimizes potential internal part binding caused by excessive installation torque or variations in cavity/cartridge machining. The CNFEXAN operates effectively up to a capacity of 40 gpm (160 L/min) and can be fitted into a T2A cavity with a series 2 configuration. It is designed for easy maintenance with available Viton seal kits and requires an installation torque between 45-50 lbf ft (61-68 Nm). With its robust design and customizable features, the Sun Hydraulics CNFEXAN valve is an optimal choice for systems requiring dependable performance under variable pressures and flow conditions.
