The Sun Hydraulics COFBXFV (COFBXFV) is a high-performance, pilot-to-close check cartridge valve designed for precise hydraulic control. This valve facilitates flow from port 1 to port 2 while effectively blocking any reverse flow, ensuring reliable operation in hydraulic systems. The COFBXFV operates with 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. It is specifically built to handle maximum operating pressures up to 5000 psi and has a flow capacity of up to 40 gpm. Key features include Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This construction detail enhances the durability and reliability of the valve in demanding applications. The valve also incorporates a maximum leakage rate of only one drop per minute at 110 SUS (24 cSt), showcasing its effectiveness in maintaining system integrity. Additionally, the COFBXFV model weighs approximately 0.50 lb and requires an installation torque between 45 - 50 lbf ft. It is compatible with Viton seal kits for enhanced performance under various conditions. This model is particularly suited for use in regeneration circuits where dependable performance is crucial. Its robust design and precise engineering make it an essential component for advanced hydraulic systems seeking efficient and effective fluid control solutions.

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.
