The Sun Hydraulics COFCXAN (COFCXAN) is a robust and efficient pilot-to-close check cartridge valve designed for high-pressure hydraulic systems. This valve features a nominal pilot ratio of 1.8:1, allowing it to close against pressures up to 1800 psi (125 bar) when the pilot port is pressurized to 1000 psi (70 bar). It facilitates flow from port 1 to port 2 while securely blocking reverse flow, ensuring stable operation in various hydraulic applications. The COFCXAN valve incorporates Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This design enhances the durability and reliability of the valve under demanding conditions. The maximum operating pressure for this model is 5000 psi (350 bar), and it has a maximum flow capacity of 40 gpm (160 L/min), making it suitable for substantial hydraulic flows. Other technical specifications include a maximum valve leakage at 110 SUS (24 cSt) of approximately one drop per minute, indicating excellent sealing performance. The valve installation requires a specific torque range between 45 - 50 lbf ft (61 - 68 Nm), and it has a compact model weight of about .50 lb (0.25 kg). For maintenance or repairs, a Viton seal kit can be used, ensuring long-term resilience against fluid and temperature-induced wear. Overall, the COFCXAN is engineered to provide reliable performance in controlling fluid flow in hydraulic systems, preventing reverse flow effectively under all conditions with equal pressures at all ports resulting in the valve remaining closed. Its specialized features make it particularly useful for applications requiring precise control over high-pressure operations.

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 external pilot port opposes pressure at port 1 at a ratio of 1.8:1. Port 3 is blocked.
- 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.
- 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.
