The Sun Hydraulics COFCXDN (COFCXDN) is a spring-biased closed, pilot-to-close check cartridge valve specifically designed for hydraulic applications requiring controlled flow and reliable shutoff. The valve facilitates flow from port 1 to port 2 while blocking reverse flow, ensuring operational stability and security. It features a nominal pilot ratio of 1.8:1, meaning it requires significantly higher pressure at the pilot port relative to the main port to close, which enhances its responsiveness and control under varying pressure conditions. This model is equipped with Sun's floating style construction that minimizes potential internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This design detail contributes to the valve\u2019s durability and consistent performance even under challenging installation conditions. The COFCXDN is built to handle a maximum flow capacity of 40 gpm (160 L/min) and can withstand a maximum operating pressure of 5000 psi (350 bar). Its robust build includes a seal kit made from Viton for enhanced resistance against high temperatures and chemical degradation. The valve's precise engineering ensures minimal leakage at high pressures, with a maximum valve leakage specified at less than one drop per minute. With its T2A cavity compatibility and specific dimensions including a hex size of 1 1/8 inches (28.6 mm) and an installation torque requirement between 45-50 lbf ft (61-68 Nm), the COFCXDN is tailored for easy integration into various hydraulic systems without necessitating extensive modifications. Weighing just about .50 lb (0.25 kg), it provides a lightweight yet powerful solution for controlling hydraulic flow efficiently and reliably in specialized industrial applications.

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.
