The Sun Hydraulics CXHCXFN (CXHCXFN) is a versatile hydraulic check valve designed for high-performance applications requiring minimal leakage. This valve operates as a standard 2-port check valve within a 3-port cavity, with the third port effectively blocked off. Ideal for scenarios where an existing three-port cavity needs to be utilized, the CXHCXFN ensures efficient operation by allowing free flow from one port to another while preventing backflow. This check valve boasts an impressive capacity of up to 80 gpm (320 L/min) and can handle maximum operating pressures of up to 5000 psi (350 bar). It features Sun Hydraulics' floating style construction which reduces the risk of internal parts binding, a common issue caused by excessive installation torque or variations in cavity/cartridge machining. This design aids in maintaining consistent performance and longevity of the valve. The CXHCXFN is also noted for its extremely low leakage rates, with maximum leakage not exceeding 1 drop per minute (0.07 cc/min), ensuring that hydraulic systems maintain their integrity and efficiency under various conditions. The valve's hex size is 1-1/4 inches (31.8 mm), and it requires an installation torque between 150-160 lbf\u00b7ft (203-217 Nm). For maintenance or replacement needs, it utilizes a Viton seal kit designated as part number 990017006. This check valve is particularly suitable for applications requiring reliable non-return functionality in high-pressure systems, making it an essential component in various hydraulic circuit configurations where space and existing port constraints are considered.
