The Sun Hydraulics CODALAN (CODALAN) is a versatile and robust spring-biased closed, pilot-to-close check cartridge valve designed for efficient hydraulic control in various applications. This valve facilitates flow from port 1 to port 2 while effectively blocking any reverse flow, ensuring operational reliability and system safety. With its nominal pilot ratio of 1.8:1, the CODALAN can close against higher pressures at port 1 when influenced by sufficient pressure at the pilot port, making it ideal for regeneration circuits where such control dynamics are crucial. Key features include a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 20 gpm (80 L/min), which accommodate substantial hydraulic demands. The valve is engineered to minimize leakage, with a maximum valve leakage rate of only one drop per minute at 110 SUS (24 cSt). The precision in design extends to its installation requirements, with specific torque settings between 30-35 lbf ft (41-47 Nm) to prevent internal binding due to excessive installation torque or cavity/cartridge machining variations. Additionally, the CODALAN model incorporates Sun's floating style construction which enhances the durability and reliability of the valve under varied operational conditions. The model also comes with options for EPDM seals suitable for systems using phosphate ester fluids, highlighting its adaptability in different fluid environments. This cartridge's robust construction and thoughtful engineering make it a dependable choice for high-demand hydraulic applications requiring precise backflow prevention and control.

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.
