The Sun Hydraulics COKAXCN (COKAXCN) is a sophisticated spring-biased closed, pilot-to-close check cartridge valve designed for specific hydraulic applications. It features a 1.8:1 pilot ratio and allows fluid flow from port 1 to port 2 while preventing reverse flow under any condition. The valve operates with a nominal pilot ratio where pressure at the pilot port can close the valve against higher pressures at port 1, effectively controlling flow based on differential pressures across the ports. This model is engineered for optimal performance in Sun's T19AU cavity to achieve its full capacity of 240 gpm (900 L/min). When installed in the standard T19A cavity, the valve will operate at reduced capacity. The maximum operating pressure for this valve is substantial, reaching up to 5000 psi (350 bar), and it has a very low maximum leakage rate of approximately one drop per minute at 110 SUS (24 cSt). The COKAXCN also incorporates Sun\u2019s floating style construction, which reduces risks of internal parts binding that could be caused by excessive installation torque or variations in cavity/cartridge machining. This design feature enhances the reliability and longevity of the valve in demanding operational conditions. Additionally, this model is built to resist corrosion, making it suitable for use in environments where corrosion resistance is critical. The cartridge's durability and robust construction ensure that it can handle rigorous use without compromising performance. Overall, the Sun Hydraulics COKAXCN valve is an essential component for systems requiring precise control over high-pressure fluid flows, particularly effective in regeneration circuits where reliability and performance are paramount.

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.
