Hefeng Technology Stainless Steel Pneumatic Butterfly Valve Product Introduction:

Hefeng Technology stainless steel pneumatic butterfly valve is a sanitary and economical on/off valve that can be used in automatic or manual systems. Due to its large opening area, low fluid resistance, and gentle handling of products with low to medium viscosity, it has become the main solution for modern processing technology. Stainless steel pneumatic butterfly valves are used in food, dairy, brewing systems, and biopharmaceutical applications.
