The Sun Hydraulics COKAXCV (COKAXCV) is a spring-biased closed, pilot-to-close check cartridge valve with a nominal pilot ratio of 1.8:1, facilitating flow from port 1 to port 2 while blocking reverse flow. This valve is specifically designed for use in regeneration circuits. It operates optimally in Sun's T19AU cavity to achieve its full capacity, although it can also fit in the standard T19A cavity with reduced capacity. The valve ensures that a pressure of 1000 psi at the pilot port will close against a pressure of 1800 psi at port 1, and any decrease in pilot pressure might temporarily open the valve. This model incorporates Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining, enhancing its reliability and performance consistency. The valve's maximum operating pressure stands at 5000 psi, with a maximum flow capacity of 240 gpm. It features highly corrosion-resistant cartridges suitable for corrosive environments, indicated by model code suffixes AP or LH. Installation specifications include a hex size of 1\u215d inches and an installation torque range of 350-375 lbf ft. The model weighs approximately 2.60 lbs and uses Viton seals for enhanced durability under various operational conditions. This configuration ensures that the valve maintains minimal leakage, with a maximum rate of about one drop per minute under standard conditions defined by a viscosity of 110 SUS (24 cSt). This precision-engineered component is critical for applications requiring robust performance and reliability in managing hydraulic flows within specified pressure parameters.

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.
- These valves will work in Sun's standard T-19A cavity at lower capacity. To realize the full stated capacity, the T-19AU cavity should be used.
- 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.
- 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.
