The Sun Hydraulics CODBLEV (CODBLEV) is a high-performance, pilot-to-close check cartridge valve designed for hydraulic applications requiring controlled flow direction and prevention of reverse flow. This valve operates by allowing fluid to flow from port 1 to port 2 while blocking any reverse flow from port 2 back to port 1. The nominal pilot ratio of 1.8:1 ensures that the valve remains closed under equal pressure conditions across all ports, promoting reliable operation in various hydraulic systems. Key specifications include a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 20 gpm (80 L/min), making it suitable for a wide range of industrial applications. The valve features Sun\u2019s floating style construction which minimizes potential internal part binding caused by excessive installation torque or cavity/cartridge machining variations. This innovative design enhances overall durability and performance consistency. The CODBLEV is equipped with Viton seals, ensuring excellent compatibility with various hydraulic fluids and environmental conditions. Additionally, the model has a tight maximum valve leakage rate at 110 SUS (24 cSt) of only about one drop per minute (0.07 cc/min), highlighting its efficiency in maintaining system integrity even under high pressure. Installation is facilitated by a hex size of 7/8 inch (22.2 mm) and recommended torque settings ranging from 30-35 lbf ft (41-47 Nm). Weighing just 0.30 lb (0.15 kg), the CODBLEV offers an optimal balance between robustness and ease of handling in system integration or maintenance tasks.

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.
- 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.
- 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.
