The Sun Hydraulics COKAXAV (COKAXAV) is a meticulously engineered pilot-to-close check cartridge valve designed for high-performance hydraulic systems. This valve facilitates flow from port 1 to port 2 while effectively blocking any reverse flow, ensuring operational integrity and system reliability. The COKAXAV operates with a nominal pilot ratio of 1.8:1, where a pressure of 1000 psi at the pilot port can close the valve against a pressure of 1800 psi at port 1. Constructed to fit seamlessly into Sun's T19A cavity for lower capacity applications, it achieves its full functionality when installed in the T19AU cavity. This versatility allows it to be adapted to different system requirements without compromising on efficiency or performance. With its maximum operating pressure standing at an impressive 5000 psi and a flow capacity up to 240 gpm, this valve is equipped to handle substantial hydraulic loads. The COKAXAV features Sun Hydraulics' floating style construction which minimizes internal parts binding\u2014a common issue caused by excessive installation torque or variations in cavity/cartridge machining. This design enhances the durability and longevity of the valve under demanding operational conditions. Additionally, this model incorporates corrosion-resistant materials, making it suitable for use in environments where corrosion is a potential risk. The meticulous attention to leakage control is evident as it allows only minimal leakage of up to 1 drop per minute at 110 SUS viscosity, ensuring that the hydraulic systems remain clean and efficient with minimal fluid loss. This combination of robust construction, precise control capabilities, and high adaptability makes the Sun Hydraulics COKAXAV an essential component for advanced hydraulic systems requiring reliable check functionalities in both standard and corrosive 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.
- 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.
