Powder Butterfly Valve

Powder Butterfly Valve is an open/close valve designed specifically for powder and granular materials. It adopts an anti accumulation flow channel and sealing structure, which can efficiently control the transportation of dry powder and granular media, prevent blockage and leakage.Widely used in industries such as building materials, grain processing, chemical engineering, and feed, it is suitable for powder silo discharge, conveying pipeline connection and disconnection, controlling media such as cement, flour, plastic particles, etc., and is suitable for dry dust conditions.

Common Types

  • Soft sealed powder butterfly valve: with elastic valve seat sealing, it prevents dust leakage and is suitable for low-pressure and room temperature powder
  • Hard sealed powder butterfly valve: Metal sealed wear-resistant, high-temperature resistant, suitable for hard particles and high-temperature powders
  • Pneumatic powder butterfly valve: Pneumatic drive for fast opening and closing, suitable for automated powder conveying lines
  • Manual powder butterfly valve: Handwheel operation, easy maintenance, suitable for small flow powder control scenarios

Structural Advantages & Corresponding Benefits

  1. Anti accumulation streamline flow channel structur

  • Special point: Smooth inner wall of the flow channel without dead corners, rounded transition at the edge of the butterfly plate, and no material retention area
  • Result:Eliminate powder bridging blockage, smooth discharge, and reduce material residue waste

  1. Wear resistant sealing valve seat structure

  • Special point: The valve seat is made of wear-resistant polyurethane material, tightly adhered to the butterfly plate, and has a dust-proof lip edge
  • Result: Good sealing and leak proof effect, resistant to powder erosion and wear, extending the service life of the valve
