The Sun Hydraulics COKAXBN (COKAXBN) is a high-performance, spring-biased closed, pilot-to-close check cartridge valve designed for efficient hydraulic flow control. This valve facilitates flow from port 1 to port 2 while blocking reverse flow, ensuring reliable operation in various hydraulic applications. With a nominal pilot ratio of 1.8:1, the valve can close against higher pressures at port 1 when appropriately pressurized at the pilot port, making it ideal for regeneration circuits where such control is necessary. Engineered for compatibility with Sun's T19A cavity at reduced capacities, the COKAXBN reaches its full capacity when used with the T19AU cavity. It supports a maximum operating pressure of up to 5000 psi (350 bar) and has a maximum capacity of 240 gpm (900 L/min), which suits it for substantial hydraulic systems. The valve also features minimal leakage rates and robust construction that includes Sun's floating style design to prevent internal parts binding due to installation or machining variations. This cartridge valve is also equipped to handle corrosive environments when specified with AP or LH model code suffixes, thanks to its corrosion-resistant build. It has precise installation requirements with recommended torque settings to ensure optimal performance without damage during setup. Overall, the COKAXBN offers reliability and precision in controlling hydraulic flow in complex systems.

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.
- These valves will work in Sun's standard T-19A cavity at lower capacity. To realize the full stated capacity, the T-19AU cavity should be used.
- 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.
- 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.
