The Sun Hydraulics CODALFN (CODALFN) is a highly efficient and robust spring-biased closed, pilot-to-close check cartridge valve designed to facilitate precise hydraulic control in various applications. With a nominal pilot ratio of 1.8:1, this valve ensures that a pressure of 1000 psi at the pilot port can close against a pressure of 1800 psi at port 1, making it particularly effective in regeneration circuits where such control is crucial. The valve permits flow from port 1 to port 2 while securely blocking any reverse flow from port 2 to port 1 under all conditions, maintaining system integrity and performance. This model has been engineered with minimum clearance between the spool and sleeve, along with a positive seal on the pilot piston diameter, which significantly reduces the potential for silting\u2014a common issue in less refined models. This design feature helps in maintaining consistent operation even under varying pressure conditions where there might be decay or loss of pilot pressure momentarily. The CODALFN is also noted for its durability and reliability due to Sun Hydraulics' floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum operating pressure capability of 5000 psi and a flow capacity up to 20 gpm, this valve is equipped to handle demanding hydraulic tasks efficiently. The model also incorporates corrosion-resistant options suitable for use in harsh environments, further extending its applicability across different settings without compromising performance. Overall, the Sun Hydraulics CODALFN stands out for its precision in controlling hydraulic flows, exceptional reliability even in challenging conditions, and adaptability to various operational requirements making it an indispensable component in modern hydraulic systems.

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.
