The Sun Hydraulics COHAXGV (COHAXGV) is a sophisticated 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 efficiently handles pressures, allowing flow from port 1 to port 2 while securely blocking reverse flow under any conditions. The valve's operation involves pressure at the pilot port opposing the pressure at port 1 with a precise ratio, ensuring reliable closure against higher pressures at port 1. It is specifically engineered for use in regeneration circuits where such control and reliability are crucial. Constructed to withstand up to a maximum operating pressure of 5000 psi (350 bar), and with a capacity of handling up to 80 gpm (320 L/min), the COHAXGV is built for robust applications. The valve ensures minimal leakage, measured at less than one drop per minute, highlighting its efficiency and tight seal capabilities. The installation requires specific torque settings between 150 and 160 lbf ft (203 - 217 Nm), ensuring secure and optimal performance. This model also incorporates Sun Hydraulics' floating style construction which minimizes internal parts binding\u2014a common issue due to excessive installation torque or cavity/cartridge machining variations. This feature significantly enhances the longevity and reliability of the valve in demanding operational environments. The COHAXGV model is also available with Viton seals (kit number: 990017006) to ensure compatibility with various hydraulic fluids and further resistance against wear and environmental factors. Overall, the Sun Hydraulics COHAXGV valve stands out for its precision, durability, and adaptability in complex hydraulic systems, making it an essential component for specialized industrial applications requiring meticulous flow control and prevention of fluid backflow.

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 pilot port opposes pressure at port 1 at a ratio of 1.8:1. This valve is most often used in regeneration circuits.
- 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.
- In the begining the CO*A's did not have a positive seal on the pilot pistons and the CO*B's did. Now the CO*A's are positively sealed and the 2 valves are mechanically identical. CO*A's are more readily available and cost less.
- Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP or /LH (see CONFIGURATION section). For further details, please see the Materials of Construction page under TECHNICAL RESOURCES.
- 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.
