The Sun Hydraulics CODALGV (CODALGV) is a high-performance, pilot-to-close check cartridge valve designed for advanced hydraulic system applications. This valve facilitates controlled flow from port 1 to port 2 while preventing reverse flow under any conditions, ensuring reliable operation and enhanced system safety. With a nominal pilot ratio of 1.8:1, it requires a specific pressure at the pilot port to close against higher pressures at port 1, effectively managing flow and pressure within hydraulic circuits. The CODALGV is particularly suited for use in regeneration circuits where precise control of fluid handling is crucial. The design incorporates minimal clearance between the spool and sleeve along with a sealed pilot piston diameter to significantly reduce the potential for silting, thus maintaining smooth operation even in high-demand situations. This valve model also features Sun's floating style construction which minimizes internal parts binding due to variations in installation torque or cavity/cartridge machining. For environments involving corrosive substances or requiring stringent cleanliness standards, the CODALGV can be configured with EPDM seals suitable for systems using phosphate ester fluids. However, these seals must not be exposed to petroleum-based fluids as they can degrade the material integrity. Technical specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 20 gpm (80 L/min), and an extremely low maximum valve leakage rate. The valve\u2019s compact design has a hex size of 7/8 in.(22.2 mm) and requires an installation torque between 30-35 lbf ft (41-47 Nm), making it easy to install while being robust enough for demanding applications. The model weighs approximately .30 lb (0.15 kg), ensuring it does not add significant weight or bulk to system assemblies.

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.
