The Sun Hydraulics CODBLAV (CODBLAV) is a spring-biased closed, pilot-to-close check cartridge valve with a 1.8:1 pilot ratio, designed to allow flow from port 1 to port 2 while blocking reverse flow. This valve operates under the principle that pressure at the pilot port can close the valve against higher pressure at port 1 by utilizing the nominal pilot ratio of 1.8:1. For example, a pressure of 1000 psi at the pilot port will effectively close against a pressure of 1800 psi at port 1. The CODBLAV is specifically engineered for use in regeneration circuits, where its capability to prevent reverse flow and maintain closure with equal pressures at all ports makes it highly effective. It incorporates Sun's floating style construction which minimizes internal part binding due to excessive installation torque or variations in cavity/cartridge machining, enhancing reliability and performance. Key specifications include a maximum operating pressure of 5000 psi and a capacity of up to 20 gpm. The valve also features minimal leakage rates with maximum leakage specified at less than one drop per minute. The installation requires specific torque settings between 30 and 35 lbf ft and utilizes a Viton seal kit for enhanced durability under varied operational conditions. This model, housed in a T11A cavity and belonging to Series 1, measures just .30 lb in weight and has an installation hex size of 7/8 inches. Its robust design coupled with precise control capabilities make it an optimal choice for demanding hydraulic applications requiring reliable check functionality under high-pressure differentials.

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.
