1. Butterfly Plate Positioning
The main component is a disc-shaped butterfly plate installed in the middle position of the valve through bearings, rotating around the valve shaft. When closed, the plate contacts the valve seat to prevent fluid passage. When open, it rotates perpendicular to the seat, allowing fluid flow through the central channel.
2. Fluid Regulation
Flow control is achieved by rotating the butterfly plate from 0° (fully closed) to 90° (fully open), with intermediate positions providing precise flow adjustment.
3. Tightness
The clamping device ensures tight contact between butterfly plate and valve seat when closed, creating an effective seal. Contact surfaces use wear-resistant materials like cemented carbide for durability.
4. Operation Modes
Available in manual (valve shaft rotation), electric (actuator), or pneumatic (compressed air control) operation options.
