The Sun Hydraulics COJBXDV (COJBXDV) is a high-performance spring biased closed, pilot-to-close check cartridge valve designed for hydraulic control systems. It features a 1.8:1 nominal pilot ratio, meaning it requires significantly higher pressure at port 1 to overcome the pilot pressure and allow flow from port 1 to port 2, effectively blocking reverse flow under any condition. This valve is specifically suitable for use in regeneration circuits where such control is necessary. This model boasts a maximum operating pressure of 5000 psi (350 bar) and can handle a flow capacity up to 160 gpm (610 L/min), ensuring robust performance in demanding applications. The COJBXDV incorporates Sun Hydraulics\u2019 floating style construction which minimizes internal parts binding, thus enhancing reliability and longevity of the valve even when subjected to excessive installation torque or variations in cavity/cartridge machining. The valve's tight leakage specification of less than one drop per minute at 110 SUS (24 cSt) ensures efficient operation with minimal fluid loss, contributing to the system's overall efficiency and cleanliness. Installation requirements include a hex size of 1 5/8 inches (41.3 mm) and an installation torque between 350 - 375 lbf\u00b7ft (474 - 508 Nm). The model weighs approximately 2.60 lbs (1.20 kg), making it a sturdy yet manageable component in hydraulic systems. Additionally, this valve model uses Viton seals (part number: 990019006), which are known for their excellent resistance to high temperatures and chemicals, providing an effective seal under various operating conditions. This specific configuration ensures that the COJBXDV is capable of meeting the rigorous demands of modern hydraulic systems where precision and durability are critical.

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.
