The Sun Hydraulics CODBXFN (CODBXFN) is a spring-biased closed, pilot-to-close check cartridge valve designed for hydraulic applications. This valve operates with a nominal pilot ratio of 1.8:1, meaning it can close against higher pressures at port 1 when controlled pressure is applied at the pilot port. Specifically, a pressure of 1000 psi at the pilot port will close the valve against a pressure of 1800 psi at port 1. It is engineered to allow flow from port 1 to port 2 while blocking reverse flow under all conditions, ensuring no flow from port 2 to port 1. The CODBXFN features Sun Hydraulics' floating style construction which minimizes internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. This construction enhances the reliability and performance of the valve in demanding environments. The maximum operating pressure for this model is rated at 5000 psi, and it has a capacity of up to 20 gpm. Additionally, the model incorporates Viton seals for enhanced durability and chemical resistance. This valve is particularly useful in regeneration circuits where precise control over flow and pressure is necessary. Its design ensures minimal leakage \u2014 less than one drop per minute \u2014 which contributes to its efficiency and effectiveness in hydraulic systems management. The installation specifications include a hex size of 7/8 inches and an installation torque ranging between 30 -35 lbf ft, making it compatible with standard tools and facilitating easy maintenance and handling. The compact model weighs only about .30 lb, making it lightweight yet robust enough for both industrial applications and mobile hydraulics.

This valve is a spring biased closed, pilot-to-close check cartridge that has a 1.8:1 pilot ratio. The valve allows flow from port 1 to port 2 and blocks reverse flow. Pressure at the pilot port opposes pressure at port 1 at a ratio of 1.8:1. This valve is most often used in regeneration circuits.
- Nominal pilot ratio is 1.8:1. This means that a pressure of 1000 psi (70 bar) at the pilot port will close a valve against a pressure of 1800 psi (125 bar) at port 1. Any decay or loss of pilot pressure could allow the valve to open, even if it is a momentary decay or loss.
- Pressure at the port 2 area directly opposes pilot pressure.
- Reverse flow through the valve from port 2 to port 1 is not possible under any condition.
- With equal pressures at all ports the valve is closed.
- In the begining the CO*A's did not have a positive seal on the pilot pistons and the CO*B's did. Now the CO*A's are positively sealed and the 2 valves are mechanically identical. CO*A's are more readily available and cost less.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
