The Sun Hydraulics COJAXFV (COJAXFV) is a spring-biased closed, pilot-to-close check cartridge valve with a nominal pilot ratio of 1.8:1. This valve facilitates flow from port 1 to port 2 while blocking reverse flow under any condition, ensuring that flow cannot move from port 2 back to port 1. The pressure at the pilot port counteracts the pressure at port 1 with a ratio of 1.8:1, meaning that a pressure of 1000 psi at the pilot port will close the valve against a pressure of 1800 psi at port 1. Any decay in pilot pressure, even if momentary, could cause the valve to open. This product is commonly utilized in regeneration circuits and features Sun's floating style construction which minimizes potential internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. The COJAXFV is designed for high-performance applications with a maximum operating pressure of 5000 psi and a capacity of up to 160 gpm. It also boasts minimal leakage at maximum operating conditions, with a rate of only one drop per minute. With an installation torque requirement between 350 and 375 lbf ft and equipped with corrosion-resistant capabilities (noted by model code suffixes AP or LH for specific environments), this valve is robust and reliable for stringent operational demands. The product weighs approximately 2.60 lbs and can be serviced using Viton seal kits specified by Sun Hydraulics. This model's precise engineering ensures efficient operation and durability in various hydraulic systems, making it an essential component for controlling fluid flow in high-pressure 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 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.
