The Sun Hydraulics CODAXFN (CODAXFN) is a robust, pilot-to-close check cartridge valve designed for effective management of hydraulic flows in various applications. This valve facilitates flow from port 1 to port 2 while effectively blocking any reverse flow, ensuring operational reliability and safety. The valve's functionality is enhanced by a nominal pilot ratio of 1.8:1, which means it requires a lower pilot pressure to close against higher pressure at port 1, providing efficient control under varying pressure conditions. The CODAXFN is specifically engineered to minimize the risk of silting through minimized spool and sleeve clearances and a sealed pilot piston diameter. This design consideration ensures long-term performance even in demanding environments. Additionally, the valve is equipped with EPDM seals suitable for systems using phosphate ester fluids, though these seals are sensitive to petroleum-based products. Rated for a maximum operating pressure of 5000 psi (350 bar) and with a capacity of up to 20 gpm (80 L/min), the CODAXFN can handle significant hydraulic flow rates making it suitable for high-capacity systems. The valve's construction incorporates Sun Hydraulics' floating style design which reduces the likelihood of internal parts binding due to installation or machining discrepancies. The cartridge is also available in corrosion-resistant configurations (model codes suffix AP or LH), enhancing its usability in corrosive environments without compromising its integrity or performance. Ideal for use in regeneration circuits, this valve model stands out for its reliability, precision, and adaptability to diverse hydraulic system requirements.

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.

  • Minimum clearances between the spool and sleeve and a seal on the pilot piston diameter significantly reduce the potential for silting.
  • 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.
  • Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
  • 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.
