  • Often used on both the blower and trailer, designed to prevent product backflow if a product line should become plugged.


  • When in use the flapper can swing completely out of the air path, resulting in increased air flow and subsequently increased product flow.
  • Complete repairs can easily be carried out on all high flow swing check valves without removing from the tank.


  • Flapper return springs are standard
  • Huck bolted flapper assembly prevents loose parts from contaminating the product.


  • Aluminum body and inspection lid
  • Stainless steel hardware
  • All white EPDM & silicone seals are compliant with FDA

Safety notes

  • Inspection lids can be removed to facilitate routine flapper assembly inspections (system must not be in service during inspections or repair.)
