High-wear, pneumatically actuated rotary gate valve engineered for pressurized and vacuum pneumatic conveying systems. The valve features fully ceramic sealing faces that are precision ground and polished to deliver reliable shutoff and outstanding abrasion resistance in demanding applications such as coal-fired power plants, steel mills, cement and bulk cereals handling.

Key benefits

  • Durable ceramic-to-ceramic sealing faces provide superior wear resistance and extended service life in abrasive, particulate-laden flows.
  • Rotary valve-plate action prevents ash and dust buildup on sealing surfaces, maintaining tighter shutoff and reducing maintenance frequency.
  • Short-stroke rotary actuation reduces mechanical wear compared with long-stroke designs and enables fast, positive cycling under pneumatic control.
  • Flanged connection and customizable face-to-face length simplify integration into existing piping and conveying systems.
  • Designed and tested to common industrial standards for pressure and dimensional compatibility.
