The Sun Hydraulics COFBXAV (COFBXAV) is a spring-biased closed, pilot-to-close check cartridge valve with a 1.8:1 pilot ratio. This valve facilitates flow from port 1 to port 2 while completely blocking any reverse flow from port 2 to port 1 under all conditions. It is designed to be used primarily in regeneration circuits, ensuring reliable operation and control of hydraulic fluid direction and pressure. The COFBXAV features a nominal pilot ratio of 1.8:1, meaning that a pressure of 1000 psi at the pilot port can close the valve against a pressure of 1800 psi at port 1. The valve remains closed with equal pressures at all ports, and any loss or decay in pilot pressure can momentarily open the valve. This model incorporates Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. Key specifications include a maximum operating pressure of 5000 psi, a flow capacity of up to 40 gpm (160 L/min), and maximum valve leakage specified at less than one drop per minute. The COFBXAV is also equipped for easy installation with a hex size of 1-1/8 inches and an installation torque range between 45-50 lbf-ft. Weighing just 0.50 lb, this model is compact yet robust enough for demanding applications requiring precise hydraulic control and reliability.

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.
