The Sun Hydraulics CODBLDV (CODBLDV) is a sophisticated pilot-to-close check cartridge valve designed for specific hydraulic applications. It features a nominal pilot ratio of 1.8:1, allowing it to close against higher pressures at port 1 when the appropriate pressure is applied at the pilot port. This valve is specifically engineered to allow flow from port 1 to port 2 while completely blocking any reverse flow from port 2 to port 1, ensuring operational reliability and safety in hydraulic systems. The CODBLDV valve operates with a maximum capacity of 20 gpm (80 L/min) and can withstand a maximum operating pressure of up to 5000 psi (350 bar). Its design incorporates Sun's floating style construction which minimizes internal part binding due to excessive installation torque or variations in cavity/cartridge machining, enhancing the valve's durability and performance consistency. This model is commonly utilized in regeneration circuits where its capability to prevent reverse flow and maintain control over fluid movement is crucial. The valve's dimensions include a hex size of 7/8 in. (22.2 mm) and it requires an installation torque between 30 - 35 lbf ft (41 - 47 Nm). Weighing just .30 lb (0.15 kg), the CODBLDV is compact yet robust, equipped with Viton seals for enhanced performance under varying conditions. Overall, the Sun Hydraulics CODBLDV check cartridge offers precise control and reliability for demanding hydraulic applications, ensuring efficient operation and prevention of fluid backflow in critical system parts.

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.
