Counterbalance Cartridge

Counterbalance valves are also known as over-centre valves or motion control valves. They are designed to control the motion of overrunning loads.

Technical requirements:

  • Load holding at "zero leakage"
  • Excellent control of negative loads during operations and throughout flow range
  • Quick response time
  • Pressure relief protection against overloads
  • Energy saving
  • Tolerance to oil contamination
  • Compact design
