The Sun Hydraulics COJBXZV (COJBXZV) is a robust, pilot-to-close check cartridge valve designed for high-performance hydraulic applications. This valve facilitates unidirectional flow from port 1 to port 2 while preventing reverse flow under any condition. Engineered with a nominal pilot ratio of 1.8:1, it requires a pilot pressure of 1000 psi (70 bar) to counteract a higher pressure of up to 1800 psi (125 bar) at port 1, effectively maintaining valve closure in demanding environments. The COJBXZV features Sun\u2019s proprietary floating style construction, which significantly reduces the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This design enhancement ensures reliable and consistent performance across various applications, particularly in regeneration circuits where precise control of hydraulic flow is critical. With a maximum operating pressure capacity of 5000 psi (350 bar) and a flow capacity up to 160 gpm (610 L/min), the valve is suitable for high-flow systems requiring meticulous backflow prevention. It also boasts minimal leakage at maximum operating conditions, with a rate not exceeding one drop per minute. The valve's robust construction includes a hex size of 1-5/8 inches (41.3 mm) and an installation torque range between 350 and 375 lbf-ft (474 - 508 Nm), ensuring secure fitting and durability. Additionally, the model weighs approximately 2.60 lbs (1.20 kg), making it substantial yet manageable for various installations without compromising on strength or functionality. The use of Viton seals further enhances its operational reliability by providing excellent resistance against high temperatures and chemical degradation, ensuring long-term performance stability in diverse hydraulic systems.

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.
