The Sun Hydraulics CODBXEV (CODBXEV) is a high-performance, pilot-to-close check cartridge valve designed for hydraulic applications requiring controlled flow and prevention of reverse flow. This valve facilitates flow from port 1 to port 2 while effectively blocking any reverse flow from port 2 to port 1 under all conditions, ensuring operational reliability and safety. With a nominal pilot ratio of 1.8:1, the CODBXEV requires a pilot pressure of 1000 psi to close against a higher pressure of 1800 psi at port 1, making it suitable for applications where precise pressure balancing is necessary. This model is particularly useful in regeneration circuits where such balance and control are critical. The valve's design incorporates Sun Hydraulics' floating style construction which minimizes internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. This feature enhances the durability and longevity of the valve under rigorous conditions. The CODBXEV has a maximum operating pressure capacity of 5000 psi and can handle flows up to 20 gpm. It is constructed with Viton seals for enhanced chemical resistance and durability, ensuring minimal leakage (maximum leakage rated at one drop per minute). The valve's hex size is 7/8 inches, with an installation torque requirement between 30 - 35 lbf ft. Weighing just about .30 lb, this model combines lightweight design with robust performance capabilities. Overall, the Sun Hydraulics CODBXEV check cartridge offers reliable performance in hydraulic systems requiring precise control over flow and pressure, particularly suited to applications involving high-pressure differentials and the need for preventing reverse flow effectively.

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.
