The Sun Hydraulics COFAXEE (COFAXEE) is a high-performance check cartridge valve designed for hydraulic systems requiring reliable, pilot-to-close operations. This valve facilitates flow from port 1 to port 2 while effectively blocking any reverse flow, ensuring stable operation in various hydraulic applications. It features a nominal pilot ratio of 1.8:1, which means 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's design prevents any reverse flow from port 2 to port 1 under all conditions, maintaining system integrity and performance. The COFAXEE valve is specifically useful in regeneration circuits where precise control over fluid handling and direction is crucial. It incorporates Sun's floating style construction which minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With a maximum operating pressure capacity of 5000 psi and a flow capacity up to 40 gpm, this valve is built to handle demanding tasks efficiently. Equipped with EPDM seals, the COFAXEE cartridge is suitable for systems using phosphate ester fluids; however, exposure to petroleum-based fluids can damage these seals. The model also features corrosion-resistant options for use in harsh environments. The installation requires specific torque settings between 45 and 50 lbf ft, ensuring secure and optimal performance. Weighing just .50 lb, this compact yet robust component integrates seamlessly into various system setups without adding significant weight 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.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP or /LH (see CONFIGURATION section). For further details, please see the Materials of Construction page under TECHNICAL RESOURCES.
- 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.
