Sun Hydraulics counterbalance cartridges, modulating devices for load holding and motion control, can be directly integrated into your actuator or applied using manifolds with many mounting options.

  • Offer hose break protection
  • Prevent loads from drifting
  • Control overrunning loads
  • Provide overcenter load control
  • Protect against pressure due to thermal expansion
  • Are physically interchangeable with pilot-to-open check cartridges (same number of ports, same cavities, same flow path for a given frame size)

Standard, 4000 psi Maximum Setting

  • Load holding to 3000 psi with 4000 psi valve setting
  • Maximum valve leakage at reseat = 5 drops/min.
  • Reseat exceeds 85% of set pressure
  • Factory pressure setting established at 2 in³/min.
  • Counterbalance valves should be set at least 1.3 times the maximum load induced pressure.
  • Back pressure at port 2 adds to the effective relief setting at a ratio of 1 plus the pilot ratio times the back pressure.
