Counterbalance valve 3:1 60l/m SUN T-11A

3:1 pilot ratio, standard capacity counterbalance valve

Counterbalance valves with pilot assist are meant to control an overrunning load. The check valve allows free flow from the directional valve (port 2) to the load (port 1) while a direct-acting, pilot-assisted relief valve controls flow from port 1 to port 2. Pilot assist at port 3 lowers the effective setting of the relief valve at a rate determined by the pilot ratio. Other names for this valve include motion control valve and over-center valve.

  • Counterbalance valves should be set at least 1.3 times the maximum load induced pressure.
  • Turn adjustment clockwise to decrease setting and release load.
  • Full clockwise setting is less than 14 bar.
  • Backpressure at port 2 adds to the effective relief setting at a ratio of 1 plus the pilot ratio times the backpressure.
  • Reseat exceeds 85% of set pressure when the valve is standard set. Settings lower than the standard set pressure may result in lower reseat percentages.
  • Sun counterbalance cartridges can be installed directly into a cavity machined in an actuator housing for added protection and improved stiffness in the circuit.
  • Two check valve cracking pressures are available. Use the 1,7 bar check unless actuator cavitation is a concern.
  • All 3-port counterbalance, load control, and pilot-to-open check cartridges are physically interchangeable (i.e. same flow path, same cavity for a given frame size).
  • This valve does not have positive seals on the pilot section and will pass up to 45 ml/min.@70 bar between port 2 and port 3. This is a consideration in master-slave circuits and in the leak testing of valve-cylinder assemblies.
  • 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.
