The Sun Hydraulics CODALZV (CODALZV) is a sophisticated pilot-to-close check cartridge valve designed for high-performance hydraulic systems. This valve facilitates flow from port 1 to port 2 while preventing reverse flow under any conditions, ensuring efficient operation in applications such as regeneration circuits. It features a nominal pilot ratio of 1.8:1, which means that a pressure of 1000 psi at the pilot port can close the valve against a pressure of 1800 psi at port 1. The design includes minimal clearances between the spool and sleeve, along with a sealed pilot piston diameter, significantly reducing the potential for silting and ensuring reliable operation. The CODALZV is engineered to handle a maximum operating pressure of up to 5000 psi and has a flow capacity of up to 20 gpm. It incorporates Sun\u2019s unique floating style construction which minimizes internal part binding due to excessive installation torque or cavity/cartridge machining variations. This model also features corrosion-resistant options suitable for use in corrosive environments, indicated by specific model code suffixes. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. The valve\u2019s robust construction ensures minimal leakage (maximum leakage at 110 SUS is approximately one drop per minute) and it requires an installation torque between 30 - 35 lbf ft. The compact design results in a lightweight model weighing only about .30 lb, making it easy to handle and install in various system configurations.

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.
