Comparison of Control Valves

Belimo - Ball Valve vs. Short Stroke Valve

Comparison: Control Valves with different operation principles

See the differences between Pressure independent "Short Stroke Control Valves with Thermal Actuator" and "Ball Valves with Electromechanical Rotary Actuators" in terms of:

  • Reaction behaviour when opening and Closing
  • Leakage, when valves are fully closed
  • Power consumption

Compared Products:

1x Belimo Ball valve with electro mechanical actuator
4x Short stroke valves with thermal actuators from different manufacturers (new condition)
3x Short stroke valves with thermal actuators used in a project (aged 2 years)

Starting Conditions:

  • All control valves are isolated with ball valves
  • All valves are fully closed
  • Applied pressure 1.1 bar

Summary:

Belimo electromechanical actuators:

  • Definite and clear reaction when opening and closing
  • Minimal power consumption, no thermal waste

Belimo Ball Valves:

  • Precise Control
  • Self-cleaning
  • No leakage air bubble tight
