The Sun Hydraulics CODALDV (CODALDV) is a high-performance, pilot-to-close check cartridge valve designed to ensure efficient flow regulation and prevent reverse flow in hydraulic systems. With a 1.8:1 nominal pilot ratio, this valve supports a maximum operating pressure of 5000 psi (350 bar) and handles up to 20 gpm (80 L/min). The valve allows fluid transfer from port 1 to port 2 while blocking any reverse flow, maintaining system integrity even under varying pressure conditions. The CODALDV features a robust design that includes minimum clearances between the spool and sleeve along with a positively sealed pilot piston, which significantly reduces the potential for silting, ensuring reliable operation even in demanding environments. This model is equipped with EPDM seals suitable for systems using phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. This valve's construction incorporates Sun Hydraulics' floating style design which minimizes internal part binding due to excessive installation torque or cavity/cartridge machining variations. The valve's dimensions include a hex size of 7/8 in. (22.2 mm) and it requires an installation torque of 30 - 35 lbf ft (41 - 47 Nm). Weighing only about .30 lb (0.15 kg), the CODALDV offers a compact yet powerful solution for hydraulic circuit applications requiring reliable check functions and effective flow control.

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.
