The Sun Hydraulics CODALBV (CODALBV) is a high-performance pilot-to-close check cartridge valve designed for advanced hydraulic system applications. This valve features a 1.8:1 pilot ratio, allowing controlled flow from port 1 to port 2 while blocking reverse flow under any condition, ensuring reliable operation in critical environments. The valve's design includes minimal clearances between the spool and sleeve, along with a positively sealed pilot piston which significantly reduces the risk of silting, enhancing its durability and performance consistency. The Sun Hydraulics CODALBV is engineered to operate efficiently with a maximum capacity of 20 gpm (80 L/min) and can withstand up to 5000 psi (350 bar) of operating pressure. It is particularly useful in regeneration circuits where precise control of fluid flow is necessary. The valve\u2019s robust construction includes corrosion-resistant options suitable for harsh environments, indicated by specific model code suffixes like AP or LH. Incorporating Sun\u2019s floating style construction, the CODALBV minimizes internal parts binding due to installation torque or cavity/cartridge machining variations, promoting longer life and reduced maintenance needs. Notably, this model uses Viton seals for standard configurations but can be equipped with EPDM seals when used with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided with EPDM seals as it could lead to damage. Overall, the Sun Hydraulics CODALBV valve offers superior reliability and performance for hydraulic systems requiring precise control over fluid handling and directionality under varied pressure conditions. Its technical sophistication makes it an ideal choice for demanding applications where fluid control precision is crucial.

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.
