The Sun Hydraulics COJBXBV (COJBXBV) is a high-performance, pilot-to-close check cartridge valve designed for precise hydraulic flow control. This valve facilitates flow from port 1 to port 2 while effectively blocking any reverse flow, making it an essential component in regeneration circuits. It features a nominal pilot ratio of 1.8:1, which means that it requires a pressure of 1000 psi at the pilot port to close against a pressure of 1800 psi at port 1. The valve is designed to remain closed with equal pressures at all ports and incorporates Sun's floating style construction to prevent internal parts binding due to installation torque or cavity/cartridge machining variations. Key specifications include a maximum operating pressure of 5000 psi, and a maximum capacity of 160 gpm. It has stringent leakage standards, allowing no more than one drop per minute at 110 SUS (approximately 24 cSt). The valve's hex size is 1-5/8 inches for installation with a torque requirement between 350 and 375 lbf.ft. Weighing in at approximately 2.60 lbs, the COJBXBV ensures robust performance and reliability in demanding hydraulic applications. The design includes Viton seals for enhanced durability and resistance against high temperatures and chemicals, ensuring long service life and consistent operation under varying 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.
- 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.
