The Sun Hydraulics CODBXAN (CODBXAN) is a high-performance hydraulic valve designed for specific applications requiring precise control of fluid flow and direction. This valve functions as a spring-biased closed, pilot-to-close check cartridge with a nominal pilot ratio of 1.8:1, meaning it effectively manages the flow from port 1 to port 2 while blocking any reverse flow from port 2 to port 1 under all conditions. The valve's operation is such that pressure at the pilot port can close the valve against significantly higher pressures at port 1, specifically, a pressure of 1000 psi at the pilot can counteract up to 1800 psi at port 1. This model is particularly suited for use in regeneration circuits where control over reverse flow and leakage is critical. It ensures reliable performance even if there's a momentary decay or loss in pilot pressure, which could potentially allow the valve to open momentarily. The design incorporates Sun\u2019s floating style construction which minimizes internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. Key specifications include a maximum operating pressure of 5000 psi, a capacity of up to 20 gpm (80 L/min), and very minimal leakage rates (about one drop per minute). The CODBXAN also features robust sealing with Viton seals and has an installation torque requirement between 30-35 lbf ft. Its compact design results in a low model weight of approximately 0.30 lb, making it suitable for various hydraulic systems without adding significant bulk or complexity.

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.
