Blow-through rotary airlock valve

The VPOT Series rotary airlock valve by Kice Industries incorporates a blow-through style connection to pneumatic conveying lines. It is engineered for systems where traditional drop-through airlocks aren’t practical due to height restrictions or special product characteristics.

  • Designed for compact installations
  • Controlled flow of fine, sticky materials
  • Durable cast-iron construction

VPOT rotary airlock valve applications

The VPOT rotary airlock valve maintains consistent pneumatic conveying pressure and minimizes product buildup, making it ideal for handling fine powders, sticky food ingredients, and other materials prone to bridging. Featuring cast-iron rotors and outboard bearings, the VPOT Series offers a reliable airlock solution for food, plastics, mineral, and chemical applications requiring smooth material transfer in tight spaces.
