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
