The Sun Hydraulics CODAXBV (CODAXBV) is a high-performance, pilot-to-close check cartridge valve designed for precise hydraulic control. This valve facilitates flow from port 1 to port 2 while blocking reverse flow under any condition, ensuring reliable operation in a variety of applications. With a nominal pilot ratio of 1.8:1, the valve can close against a higher pressure at port 1 when activated by appropriate pressure at the pilot port. This feature makes it particularly useful in regeneration circuits where such control is crucial. The CODAXBV boasts an enhanced design with minimal spool to sleeve clearances and a positively sealed pilot piston that reduces the risk of silting and ensures consistent performance even under fluctuating pressure conditions. It is engineered to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity up to 20 gpm (80 L/min), making it suitable for robust hydraulic systems. Incorporating Sun's floating style construction, the CODAXBV minimizes internal parts binding which can occur due to excessive installation torque or cavity/cartridge machining variations. This design consideration extends the valve's operational life and reliability. The valve also features corrosion-resistant options for use in harsh environments, identified by specific model code suffixes. For systems utilizing phosphate ester fluids, cartridges configured with EPDM seals are available, whereas Viton seals are used for other types of hydraulic fluids to prevent seal degradation and maintain integrity throughout its service life. The compact model weighs just 0.30 lb (0.15 kg) and requires an installation torque between 30-35 lbf ft (41-47 Nm), facilitating easy installation and maintenance without compromising performance.

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.
