Adjustable Purge Valve

Adjustable Purge Valve
Material Line Valves

The Adjustable Purge Valve (APV) controls material flow from a hopper or surge bin, and is ideal for use with central drying and conveying systems.

The adjustable valve releases material into the conveying lines as needed, and then purges the material lines to prevent material cross-contamination and/or moisture regain.

The APV can be used in either dry or ambient air conveying applications

  • Design ensures complete purging
  • Flexible installation
  • Modular components; easy maintenance
  • Smooth, aluminum body
  • Easy and safe to clean
  • Dual-pump systems; one material source
