The Sun Hydraulics COHCXEN (COHCXEN) is a robust pilot-to-close check cartridge valve designed for hydraulic applications requiring controlled flow and prevention of reverse flow. This valve operates by allowing fluid to move from port 1 to port 2 while blocking any reverse flow from port 2 to port 1, ensuring stable and secure operation in various hydraulic systems. The valve 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. Constructed with Sun's floating style design, the COHCXEN minimizes potential internal part binding caused by excessive installation torque or variations in cavity/cartridge machining, enhancing its reliability and performance longevity. The valve is designed for a T17A cavity and belongs to Series 3, supporting a maximum flow capacity of 80 gpm (320 L/min) and can withstand maximum operating pressures up to 5000 psi (350 bar). Its precise construction ensures minimal leakage, measured at approximately one drop per minute under specific conditions. Additionally, the COHCXEN has an installation torque range between 150-160 lbf\u00b7ft (203-217 Nm) and weighs about 1.80 lbs (0.80 kg). The seal kit for this model uses Viton components, part number 990017006, ensuring excellent resistance to high temperatures and chemicals commonly encountered in hydraulic systems. This model's design and specifications make it suitable for applications where reliable check functions are critical under varying pressure conditions without the risk of reverse flow.

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.
