Large Diameter Butterfly Valve D343H

Product Features

1. This butterfly valve boasts a simple structure, compact body, light weight, low material consumption and small installation space. It opens and closes rapidly with 90° reciprocating rotation and requires low driving torque. Designed for cutting off, connecting and regulating pipeline medium, it delivers excellent fluid control performance and tight shut-off sealing.

2. Ideal for slurry conveyance, with minimal residual liquid left inside the pipeline cavity. It maintains reliable sealing and outstanding regulating performance even under low pressure working conditions.

3. Streamlined disc design greatly reduces fluid resistance loss, making this valve an energy-saving and low-operation-cost product.

4. The valve stem adopts a solid integral structure with precision heat treatment, providing excellent comprehensive mechanical properties, corrosion resistance and wear resistance. During opening and closing, the stem only performs rotational movement without vertical displacement, preventing packing wear and ensuring consistent, reliable sealing. It is permanently locked to the butterfly plate, and the external end features an anti-blowout design to prevent dangerous stem ejection in case of accidental connection failure.

5. Available connection options: flanged, wafer, butt weld and lug wafer connection. Actuator types include handwheel, worm gear, electric, pneumatic, hydraulic and electro-hydraulic drive, enabling remote control and fully automated operation.

 Product Advantages

1. Quick, effortless opening and closing, low fluid resistance, suitable for frequent cyclic operation.

2. Simple construction, small overall dimensions, short face-to-face length, light weight, perfectly optimized for large-diameter pipeline applications.

3. Excellent performance for slurry service, with extremely low residual liquid retention in pipelines.
