Mixproof butterfly valve DF-FHA

Sanitary stainless steel mixproof butterfly valve 

What is a mixproof butterfly valve?

DF-FHA series mixproof double seat butterfly valve is widely used in various industrial fluid process applications such as food, pharmaceutical, beverage, beer, liquor, water treatment, cosmetics, new energy, daily washing and so on. The mixproof butterfly valve provides an easy and safe means of material separation to prevent accidental mixing of materials in the event of damage to the seal. It is most commonly used to isolate materials that require safe separation and a single set of CIP cleaning (not a valve array assembly), or into the tank assembly terminal (eg, CIP return) or CIP solution into the tank (by cleaning the ball).

Double seat seal protection, Internal leakage can be observed, Valve cavity can be cleaned, Zero pollution risk
