The Sun Hydraulics COJBXAV (COJBXAV) is a robust and efficient spring-biased closed, pilot-to-close check cartridge valve designed for high-performance hydraulic systems. Featuring a 1.8:1 nominal pilot ratio, this valve efficiently allows flow from port 1 to port 2 while preventing reverse flow under any conditions. The valve's design ensures that pressure at the pilot port can close the valve against higher pressures at port 1, making it particularly suitable for use in regeneration circuits where precise control of fluid handling is necessary. This model incorporates Sun\u2019s floating style construction which minimizes potential internal parts binding due to excessive installation torque or variations in cavity/cartridge machining, enhancing reliability and performance consistency. The COJBXAV operates with a maximum capacity of 160 gpm (610 L/min) and can withstand a maximum operating pressure of up to 5000 psi (350 bar). Its tight construction guarantees minimal leakage, not exceeding 1 drop/min (0.07 cc/min), even under high-pressure operations. The valve is engineered for easy installation with a specific hex size of 1 5/8 in (41.3 mm) and an installation torque range of 350 -375 lbf\u00b7ft (474 -508 Nm). Weighing at approximately 2.60 lb (1.20 kg), the COJBXAV maintains compactness and robustness, suitable for various hydraulic applications demanding high reliability and efficiency. Additionally, it uses Viton seals (990019006) ensuring excellent compatibility with a wide range of fluids and temperature resilience.

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.
