The Sun Hydraulics COFBXCV (COFBXCV) is a high-performance, spring-biased closed, pilot-to-close check cartridge valve with a nominal pilot ratio of 1.8:1. This valve facilitates controlled fluid flow from port 1 to port 2 while preventing reverse flow from port 2 to port 1 under any condition. Engineered for optimal performance in regeneration circuits, the COFBXCV is designed to close against pressures up to 1800 psi (125 bar) at port 1 when the pilot pressure at the pilot port reaches approximately 1000 psi (70 bar). The internal mechanism includes a Sun floating style construction which minimizes potential binding of internal parts due to excessive installation torque or variations in cavity/cartridge machining. This model boasts impressive specifications such as a maximum operating pressure of 5000 psi (350 bar), a flow capacity of up to 40 gpm (160 L/min), and minimal leakage at maximum operating conditions, typically around one drop per minute (0.07 cc/min). The valve's hex size is standardized at 1-1/8 inches (28.6 mm) and requires an installation torque between 45 and 50 lbf\u00b7ft (61 - 68 Nm). Weighing just about .50 lb (0.25 kg), it also features compatibility with Viton seal kits for enhanced performance under various operating conditions. This model is particularly suited for applications requiring reliable check functionality with precise control over fluid flow and pressure, ensuring stability and robust operation even in demanding hydraulic systems setups.

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.
