Masoneilan Conventional Butterfly Control Valves

  • Description:

    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.
