The Sun Hydraulics COJAXGV (COJAXGV) is a robust, pilot-to-close check cartridge valve designed for high-performance hydraulic systems. This valve features a spring-biased closed mechanism with a nominal pilot ratio of 1.8:1, ensuring efficient operation under varying pressures. It facilitates flow from port 1 to port 2 while effectively blocking any reverse flow from port 2 to port 1, ensuring directional integrity and system reliability. The COJAXGV valve operates under a maximum pressure of 5000 psi (350 bar) and can handle a capacity up to 160 gpm (610 L/min). This makes it suitable for use in demanding applications such as regeneration circuits where precise control of fluid handling is critical. The valve is designed with Sun's floating style construction which minimizes the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining, enhancing its operational reliability and lifespan. Key specifications include a maximum valve leakage at 110 SUS (24 cSt) maintained at less than one drop per minute, indicating high sealing efficiency. Installation requires specific torque settings between 350 \u2013 375 lbf ft (474 \u2013 508 Nm), and the valve has an installation hex size of 1-5/8 inches (41.3 mm). The model weighs approximately 2.60 lbs (1.20 kg), making it sturdy yet manageable for integration into various hydraulic setups. Equipped with Viton seals as indicated by the seal kit/cartridge number Viton: 990019006, the COJAXGV ensures enhanced chemical resistance and performance durability in corrosive environments. This feature, coupled with its reliable backflow prevention capabilities and high-pressure endurance, makes the COJAXGV an essential component for advanced hydraulic systems requiring precise fluid control and long-term operational stability.

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.
- 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.
