The Sun Hydraulics CODBLFV (CODBLFV) is a high-performance spring biased closed, pilot-to-close check cartridge valve designed for advanced hydraulic system applications. This valve features a nominal pilot ratio of 1.8:1, allowing precise control where a pressure of 1000 psi at the pilot port can close the valve against a pressure of 1800 psi at port 1. It efficiently allows flow from port 1 to port 2 while blocking any reverse flow from port 2 to port 1 under all conditions, ensuring reliable operation and enhanced safety in regeneration circuits. The CODBLFV is engineered with Sun's floating style construction which minimizes potential internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. This design consideration enhances the durability and reliability of the valve in diverse operating environments. The valve's maximum operating pressure capacity is up to 5000 psi, and it can handle flow rates up to 20 gpm (80 L/min), making it suitable for robust hydraulic applications. Additionally, the model incorporates a Viton seal kit which provides excellent resistance against high temperatures and chemical degradation, further extending the operational lifespan and performance reliability of the valve. With an installation torque requirement between 30-35 lbf ft (41-47 Nm) and minimal leakage specifications at maximum operating conditions (1 drop/min or 0.07 cc/min), this model ensures efficient and leak-proof performance in critical hydraulic setups. The compact design with a weight of just .30 lb (0.15 kg) also makes it easy to integrate into various system configurations without adding significant weight or complexity.

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.
