The Sun Hydraulics COKAXBV (COKAXBV) is a high-performance, spring-biased closed, pilot-to-close check cartridge valve designed for advanced hydraulic system applications. This valve facilitates controlled flow from port 1 to port 2 while effectively blocking any reverse flow from port 2 to port 1, ensuring operational integrity and safety in a variety of settings. The nominal pilot ratio of 1.8:1 indicates that a pressure of 1000 psi at the pilot port can close the valve against a pressure of 1800 psi at port 1, making it highly effective in maintaining control under varying pressure conditions. This model is optimized for use in Sun's T19AU cavity to achieve its full capacity of up to 240 gpm/900 L/min., although it can also operate in the standard T19A cavity at reduced capacity. The maximum operating pressure for this valve is robust at 5000 psi (350 bar), with a maximum valve leakage rate specified at less than one drop per minute, ensuring minimal loss and efficient operation. The COKAXBV incorporates Sun's floating style construction which minimizes potential internal binding that could result from excessive installation torque or variations in cavity/cartridge machining. This feature enhances the durability and reliability of the valve in demanding environments. The valve is also designed to be corrosion-resistant, suitable for use in corrosive environments, indicated by specific model code suffixes AP or LH as described in Sun Hydraulics' technical resources. This product is an excellent choice for applications requiring reliable non-return functionality, particularly useful in regeneration circuits where precise hydraulic control is critical.

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.
