The Sun Hydraulics COJBXCV (COJBXCV) is a high-performance hydraulic valve designed for precision flow control in various applications. This spring-biased closed, pilot-to-close check cartridge valve features a 1.8:1 pilot ratio, allowing flow from port 1 to port 2 while blocking reverse flow under any condition. The valve operates effectively with a nominal pilot ratio, where 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 useful in regeneration circuits and incorporates Sun's floating style construction to reduce the risk of internal parts binding due to excessive installation torque or cavity/cartridge machining variations. The COJBXCV is designed for maximum operating pressures up to 5000 psi and can handle flow capacities up to 160 gpm. It features minimal leakage with only one drop per minute at maximum operating conditions, ensuring efficient and reliable performance. The robust construction includes a Viton seal kit for enhanced durability and chemical resistance, making it suitable for demanding operational environments. With its precise control capabilities and high reliability, the Sun Hydraulics COJBXCV valve is an essential component for systems requiring accurate hydraulic regulation and safety.

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.
