The Sun Hydraulics CODALZN (CODALZN) is a high-performance cartridge valve designed for precise hydraulic control. This spring-biased closed, pilot-to-close check cartridge features a 1.8:1 pilot ratio, allowing flow from port 1 to port 2 while blocking reverse flow. The valve is engineered to operate effectively in regeneration circuits, where it enhances system efficiency and reliability. It requires a pressure of 1000 psi at the pilot port to close against a pressure of 1800 psi at port 1, showcasing its robust operation under high-pressure differentials. The CODALZN valve boasts minimal internal leakage, specified at only one drop per minute, ensuring excellent performance in critical applications. It supports a maximum operating pressure of up to 5000 psi and has a flow capacity of up to 20 gpm. The design incorporates Sun's floating style construction which reduces risks associated with excessive installation torque and machining variations of the cavity/cartridge, thus safeguarding the valve's integrity and functionality over time. This model is also available with EPDM seals for compatibility with phosphate ester fluids, highlighting its versatility in different hydraulic systems. Moreover, it features corrosion-resistant options indicated by model code suffixes AP or LH for enhanced durability in corrosive environments. With a compact design weighing only 0.30 lb and requiring an installation torque between 30-35 lbf ft, the CODALZN is both easy to install and maintain, making it an ideal choice for various hydraulic applications requiring reliable check functionality.

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.
