The Sun Hydraulics COHCXAV (COHCXAV) is a high-performance, pilot-to-close check cartridge valve, engineered to facilitate controlled hydraulic flow in advanced fluid power applications. Designed to allow flow from port 1 to port 2 while completely blocking reverse flow, this valve is integral for systems requiring reliable unidirectional flow control. The COHCXAV operates with a nominal pilot ratio of 1.8:1, meaning that it can close against higher pressures at port 1 when subjected to sufficient pilot pressure at its external pilot port. This feature is particularly beneficial in applications where pressure control and stability are necessary. The valve\u2019s construction includes Sun Hydraulics' floating style design which minimizes the risk of internal parts binding\u2014a common issue arising from excessive installation torque or variations in cavity/cartridge machining. This ensures consistent performance and longevity of the valve even under stringent operational conditions. The COHCXAV can handle a maximum flow capacity of 80 gpm (320 L/min) and withstands a maximum operating pressure up to 5000 psi (350 bar), making it suitable for high-pressure applications across various hydraulic systems. Additionally, the valve's design ensures that with equal pressures at all ports, the valve remains closed, enhancing its safety and efficiency. The maximum leakage specification of this model is minimal at approximately 1 drop/min (0.07 cc/min), highlighting its effectiveness in maintaining system integrity and minimizing fluid loss. Installation specifications include a hex size of 1-1/4 inches (31.8 mm) and an installation torque range between 150 -160 lbf\u00b7ft (203 -217 Nm), ensuring easy integration into existing setups without requiring extensive modifications.

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.
