The Sun Hydraulics CODALCN (CODALCN) is a high-performance, pilot-to-close check cartridge valve designed for advanced fluid power applications. This valve features a 1.8:1 pilot ratio, enabling it to close against higher pressure differentials effectively. Specifically, it can close against a pressure of 1800 psi at port 1 when there is 1000 psi at the pilot port. The CODALCN allows flow from port 1 to port 2 while blocking any reverse flow from port 2 to port 1 under all conditions, ensuring reliable operation and enhanced control in hydraulic circuits. Constructed with precision and durability in mind, the CODALCN incorporates minimal clearances between the spool and sleeve along with a sealed pilot piston diameter that reduces potential silting issues, ensuring long-term performance even in demanding environments. Its design also includes Sun's floating style construction which minimizes internal parts binding due to installation torque or machining variations of the cavity/cartridge. The valve has a maximum operating pressure of 5000 psi and supports flows up to 20 gpm. It is designed for use in T11A cavity configurations and offers corrosion resistance options suitable for harsh environments (model codes with suffix AP or LH). Additionally, this model features EPDM seals configured for compatibility with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Overall, the Sun Hydraulics CODALCN is an essential component for systems requiring precise control over fluid flow and pressure relief in regeneration circuits or other similar applications where reliability and performance are critical.

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.
