Pneumatic butterfly valves are widely used as shut-off valves, suitable for large and medium pipelines.
Common types: stainless steel, hard-sealed, soft-sealed, carbon steel, etc.

  1. Stainless steel type: replaceable seals, reliable bidirectional sealing.

  2. Flange type: compact, lightweight, easy to install, maintain and mount at any angle.

  3. Wafer type: simple structure, small operating torque, fast 90° rotation.

  4. Soft-sealed type: pinless connection between disc and stem, avoiding internal leakage.

  5. Hard-sealed type: spherical disc design for better sealing and longer life, zero leakage after over 50,000 cycles.

  6. Near-linear flow characteristic, good regulating performance.

  7. Disc coating available (nylon, PTFE, etc.) as requested.

  8. Hard-sealed type supports flange and wafer connections
