The Sun Hydraulics COBGXFN (COBGXFN) is a high-performance, pilot-to-close check cartridge valve designed for hydraulic applications where flow control and prevention of reverse flow are critical. This valve operates by allowing fluid to pass from port 1 to port 2 while blocking any reverse flow from port 2 back to port 1, ensuring directional control and system integrity. The valve features a nominal pilot ratio of 1.8:1, which means that it requires a higher pressure at the pilot port relative to the pressure at port 1 to close the valve effectively. For instance, a pilot pressure of 1000 psi will close the valve against a pressure of 1800 psi at port 1. Constructed with hardened steel seats, the COBGXFN offers excellent wear characteristics and tolerance to contamination, making it suitable for demanding environments typically found in regeneration circuits. The design incorporates Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. The valve has a maximum operating pressure of 5000 psi and can handle flows up to 10 gpm (40 L/min). It is equipped with Viton seals for enhanced performance under varying conditions. The internal hex size for installation is 5/16 in., and the recommended torque for installing this model is between 20 - 25 lbf ft. Weighing only about 0.20 lb, this compact unit ensures minimal impact on system dynamics while providing reliable operational capabilities. Overall, the Sun Hydraulics COBGXFN check cartridge is an essential component for hydraulic systems requiring precise flow control and reliability in preventing reverse flow, contributing significantly towards enhancing system efficiency and safety.

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.

  • 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)).
  • 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.
  • 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.
