The Sun Hydraulics CODALCV (CODALCV) is a high-performance, pilot-to-close check cartridge valve designed for hydraulic applications requiring reliable one-way flow and blockage of reverse flow. This valve facilitates flow from port 1 to port 2, while effectively preventing any backflow from port 2 to port 1 under all conditions. It features a nominal pilot ratio of 1.8:1, meaning that a pilot pressure of 1000 psi is required to close the valve against a higher pressure of 1800 psi at port 1. The design includes minimum clearances and a positively sealed pilot piston which significantly reduces the risk of silting, ensuring consistent operation even under fluctuating pressures. The CODALCV valve is built with Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining\u2014enhancing durability and operational reliability. The cartridge is available with EPDM seals for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. With a maximum operating pressure capacity of up to 5000 psi and a maximum flow capacity of 20 gpm, this valve is suitable for high-pressure systems. Its robust construction includes corrosion-resistant options (identified by suffixes AP or LH in the model code), making it ideal for use in corrosive environments. The valve also features a hex size of 7/8 inches for installation, requiring an installation torque between 30 -35 lbf ft. Weighing just about .30 lb, the CODALCV combines compact design with powerful performance specifications suited for demanding hydraulic applications that require precise control over fluid handling and direction.

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.
