Description:
37002 Series Minitork* II Butterfly Control ValvesThe 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.
