The Sun Hydraulics COHCXDN (COHCXDN) is a spring-biased closed, pilot-to-close check cartridge valve designed for high-performance hydraulic systems. With a nominal pilot ratio of 1.8:1, this valve effectively allows flow from port 1 to port 2 while completely blocking reverse flow from port 2 to port 1 under any condition. This feature ensures reliable operation and prevents backflow which could potentially damage the system or reduce its efficiency. The COHCXDN operates with a maximum capacity of 80 gpm (320 L/min) and can handle a maximum operating pressure of up to 5000 psi (350 bar). The valve's design includes a T17A cavity and is part of Sun Hydraulics' Series 3. One of the key features of this model is its incorporation of Sun\u2019s floating style construction, which minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This model also boasts minimal leakage, with a maximum valve leakage rate at 110 SUS (24 cSt) being approximately one drop per minute (0.07 cc/min). For installation, the valve requires a hex size of 1-1/4 inches (31.8 mm) and an installation torque between 150 -160 lbf ft (203 -217 Nm). The overall weight of the COHCXDN model is about 1.80 lb (0.80 kg), making it robust yet manageable for various industrial applications. In addition to its technical specifications, the COHCXDN uses Viton seals for enhanced durability and chemical resistance, ensuring reliable performance across various operating conditions without succumbing easily to wear or environmental factors. This model is particularly suited for applications where precise hydraulic flow control is necessary and where system integrity against reverse flow is critical.

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.
