The Sun Hydraulics COFCXFN (COFCXFN) is a highly specialized hydraulic component designed for precise fluid control in various hydraulic systems. This spring-biased closed, pilot-to-close check cartridge valve operates with a nominal pilot ratio of 1.8:1, ensuring robust performance under varying pressure conditions. It facilitates flow from port 1 to port 2 while effectively blocking reverse flow from port 2 to port 1, thus maintaining directional control and system integrity. The valve features an external pilot port where pressure can oppose the main pressure at port 1 with a ratio of 1.8:1. For example, a pressure of 1000 psi at the pilot port can close the valve against a pressure of 1800 psi at port 1. This feature is crucial for applications requiring precise control over the opening and closing of the valve based on pilot pressure signals. The design incorporates Sun\u2019s floating style construction which minimizes potential internal part binding due to installation torque or machining variations in the cavity/cartridge. This model is housed within a T2A cavity and is part of Sun Hydraulics' Series 2 lineup, supporting maximum flow capacities up to 40 gpm (160 L/min) and withstanding pressures up to 5000 psi (350 bar). Its meticulous construction ensures minimal leakage, no more than one drop per minute at specific viscosity conditions (110 SUS /24 cSt). The valve is also designed for easy installation with specified torque requirements between 45 \u2013 50 lbf ft (61 \u2013 68 Nm) and has an overall weight of approximately .50 lb (0.25 kg). The seal kit compatible with this model uses Viton materials (990202006), enhancing its durability and performance in diverse operating environments.

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.
