The Sun Hydraulics CODAXDV (CODAXDV) is a sophisticated hydraulic cartridge valve designed for specific applications where control over fluid flow direction and pressure is crucial. This valve operates as a spring-biased closed, pilot-to-close check cartridge, featuring a nominal pilot ratio of 1.8:1. The mechanism allows fluid to flow from port 1 to port 2 while blocking any reverse flow, ensuring operational security and efficiency in systems like regeneration circuits. The CODAXDV valve is engineered to maintain minimal clearances between the spool and sleeve, reducing the potential for silting due to its seal on the pilot piston diameter. It is capable of closing against pressures up to 1800 psi (125 bar) at port 1 when there is a pressure of 1000 psi (70 bar) at the pilot port. The design includes safeguards that allow the valve to open under conditions of pilot pressure decay or loss, albeit momentarily. This model has been updated from earlier versions to include positive seals on the pilot pistons, now making it mechanically identical to other models in the series but more cost-effective and readily available. The cartridges configured with EPDM seals are specifically meant for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Sun Hydraulics has incorporated their floating style construction into this model, which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. The CODAXDV offers robust performance specifications including a maximum operating pressure of 5000 psi (350 bar), a maximum capacity of 20 gpm (80 L/min), and precise control with maximum valve leakage at merely one drop per minute. It also features practical installation dimensions such as a hex size of 7/8 in. (22.2 mm) and an installation torque range of 30-35 lbf ft (41-47 Nm). With its compact model weight of only .30 lb (0,15 kg), this valve integrates seamlessly into various hydraulic systems requiring reliable check functionalities under demanding conditions.

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.
