37002 Series Minitork* II Butterfly Control Valves The MiniTork® II is a heavy duty automatic throttling control butterfly valve that provides superior performance by incorporating the following features

  • Low Dynamic Torque – the unique cupped shape disc results in a dynamic torque considerably lower than conventional butterfly valves.
  • Bi-Directional Flow – The reverse cupped construction of the Minitork disc is not self-limiting. Accordingly, the low torque can be maintained regardless of flow direction.
  • Deflection-free and backlash-free operation. Splined and clamped construction with an ouboard ball bearing and a rigid bracket assembly provide the structural rigidity required for precise positioning.
  • Direct Mounted Positioners – Position feedback is directly connected to the valve shaft eliminating potential lost motion and providing improved positioning accuracy.
  • Triple Bearing System – provides exceptional support and guiding for the shaft.
  • Valve Position Indicator – highly visible, which allows quick visual inspection of disc position.
  • Integrally Cast Extension Bonnet – provides ability to handle wide range of process temperatures.
  • Spring Diaphragm Actuator – with total enclosure of all moving parts provides increased resistance to environmental corrosion.
  • Applicable Industrie
