The Sun Hydraulics CODAXEV (CODAXEV) 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 condition, ensuring reliable operation and system integrity. The nominal pilot ratio of 1.8:1 indicates that a pilot pressure of 1000 psi can close the valve against a higher pressure of 1800 psi at port 1, making it highly effective in various applications, particularly in regeneration circuits where such functionality is crucial. Key features include minimized potential for silting due to the minimal clearances between the spool and sleeve, alongside a seal on the pilot piston diameter which enhances its performance reliability. The valve's design incorporates Sun's floating style construction which reduces risks associated with internal parts binding due to installation torque or cavity/cartridge machining variations. Engineered for robustness, the CODAXEV can handle a maximum operating pressure of up to 5000 psi and has a flow capacity of up to 20 gpm. Its construction ensures minimal leakage, with maximum leakage specified at approximately one drop per minute. For environments involving phosphate ester fluids, cartridges configured with EPDM seals are recommended, while exposure to petroleum-based fluids should be avoided as it may damage the seals. This model also boasts corrosion resistance features suitable for corrosive environments when identified by specific model code suffixes like AP or LH. Easy installation is facilitated by a hex size of 7/8 inches and an installation torque range between 30 - 35 lbf ft. The CODAXEV weighs around .30 lb, making it lightweight yet durable for various hydraulic applications.

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.
