Flow Governor

Aichi Tokei's governors are actively working at various locations for energy-saving, labor-saving on energy control, and providing safe supply of gas.

The ones introduced here are Aichi Tokei's standard governors

  • Governor for high temperature gas
  • Governor with the precise adjustment handle
  • Governor for gas that contains sulfide
  • Other special governors
