The Sun Hydraulics COBAXDN (COBAXDN) is a highly specialized pilot-to-close check cartridge valve designed for efficient hydraulic flow management. This valve facilitates the flow from port 1 to port 2 while effectively blocking any reverse flow from port 2 to port 1, ensuring a one-way operation which is critical in various hydraulic applications, particularly in regeneration circuits. The COBAXDN operates with a nominal pilot ratio of 3:1, meaning that it requires a significantly lower pressure at the pilot port to close against higher pressure at port 1, thus providing precise control over hydraulic pressures in complex systems. The valve boasts hardened steel seats which enhance its durability and resistance to wear, even in the presence of contaminants. This makes it an ideal choice for systems where longevity and reliability are paramount. It also incorporates Sun\u2019s floating style construction which minimizes internal parts binding\u2014a common issue with installation torque or variations in cavity/cartridge machining. With a maximum operating pressure capability of 5000 psi (350 bar) and a capacity to handle up to 10 gpm (40 L/min), the COBAXDN is suitable for high-pressure applications. The valve ensures minimal leakage, maintaining efficiency with a maximum rate of only about one drop per minute at 110 SUS (24 cSt). For installations requiring specific chemical compatibility, cartridges configured with EPDM seals are recommended for systems using phosphate ester fluids. Overall, the Sun Hydraulics COBAXDN valve is engineered for performance and reliability, tailored specifically for demanding hydraulic applications that require robust control and precision.

This valve is a spring biased closed, pilot-to-close check cartridge that has a 3:1 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 3:1. This valve is most often used in regeneration circuits.
- Features hardened steel seats for excellent wear characteristics and contamination tolerance.
- Product is not available with A and B spring ranges (4 and 15 psi (0,3 and 1 bar)).
- 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.
- Nominal pilot ratio is 3:1. This means that a pressure of 1000 psi (70 bar) at the pilot port will close a valve against a pressure of 3000 psi (205 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.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- 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.
