The Sun Hydraulics COJAXDV (COJAXDV) is a high-performance, pilot-to-close check cartridge valve designed for efficient hydraulic flow control. With a nominal pilot ratio of 1.8:1, this valve facilitates flow from port 1 to port 2 while effectively blocking reverse flow under any condition, ensuring reliable operation in critical applications. Specifically crafted for use in regeneration circuits, the COJAXDV operates such that a pressure of 1000 psi at the pilot port can close the valve against a pressure of 1800 psi at port 1. This valve is engineered to remain closed with equal pressures at all ports and features Sun's floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. It boasts a maximum operating pressure of 5000 psi and has a maximum capacity of 160 gpm, making it suitable for high-demand systems. The COJAXDV also incorporates advanced sealing technologies and corrosion-resistant materials, enhancing its durability and performance in corrosive environments. Its robust design includes a maximum valve leakage rate of only one drop per minute at 110 SUS (approximately 24 cSt), ensuring minimal loss and efficient operation. The installation requires precise torque management between 350 - 375 lbf ft, and the unit has an overall weight of approximately 2.60 lbs. This model's adaptability and reliability make it an essential component for sophisticated hydraulic systems requiring precise flow control and prevention of reverse flow under all operational conditions.

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.
- 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.
