The Sun Hydraulics CODBLEN (CODBLEN) is a high-performance, pilot-to-close check cartridge valve designed for hydraulic systems requiring reliable, controlled flow. This valve facilitates the flow from port 1 to port 2 while effectively blocking any reverse flow from port 2 to port 1 under all conditions. It features a nominal pilot ratio of 1.8:1, meaning that it requires a significantly higher pressure at port 1 compared to the pilot pressure to remain closed, thus ensuring stability and control in high-pressure applications. The CODBLEN is engineered with Sun\u2019s floating style construction which reduces the risk of internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This design feature enhances the durability and reliability of the valve in demanding operational environments. The maximum operating pressure for this model is up to 5000 psi (350 bar), and it can handle flow capacities up to 20 gpm (80 L/min). With a maximum valve leakage specification at 110 SUS (24 cSt) being minimal at around 1 drop/min (0.07 cc/min), this valve demonstrates exceptional performance in maintaining system integrity. This model is equipped with Viton seals, ensuring compatibility with a wide range of hydraulic fluids and providing excellent resistance against high temperatures and chemical degradation. The installation specifications include a hex size of 7/8 inch (22.2 mm) and an installation torque range of 30 \u2013 35 lbf ft (41 \u2013 47 Nm), making it adaptable for various setups without requiring special tools or configurations. Overall, the Sun Hydraulics CODBLEN offers superior performance for regeneration circuits and other applications where precise fluid control is critical, backed by robust construction and reliable sealing capabilities.

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.
  • 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.
