The Sun Hydraulics COFCXCV (COFCXCV) is a precision-engineered pilot-to-close check cartridge valve, designed for hydraulic systems requiring reliable, one-way flow control. This valve facilitates fluid flow from port 1 to port 2 while completely blocking reverse flow from port 2 to port 1 under all conditions, ensuring operational integrity and safety. It features a nominal pilot ratio of 1.8:1, meaning that a pressure of 1000 psi at the pilot port can close the valve against a pressure of 1800 psi at port 1. The valve's operation can be influenced by the pressure at its external pilot port which opposes the pressure at port 1 with a ratio of 1.8:1. The COFCXCV is built using Sun\u2019s floating style construction which minimizes potential internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. This design enhances the durability and reliability of the valve in demanding applications. It has a maximum operating pressure capacity of up to 5000 psi and can handle flow rates up to 40 gpm. The valve also boasts minimal leakage, with a maximum rate specified at less than one drop per minute. The physical specifications include a hex size for installation at 1-1/8 inches and an installation torque range between 45 -50 lbf ft. The compact model weighs approximately .50 lb, making it suitable for various installation environments without adding significant weight or bulk. For maintenance or repair, it utilizes Viton seals (part number: 990202006), ensuring long-term performance even under harsh conditions. This valve is ideal for applications where unidirectional flow and leak-tight closure are critical for system performance 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 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.
