Sanitary butterfly valve is a stainless steel butterfly valve with high precision and purity requirements for the industries of food and beverage, beer brewing, biopharmaceutical and fine chemicals. Stainless steel sanitary butterfly valve has a simple structure, it is mainly composed of a split body, a valve disc, a valve stem and a driving. Compared with sanitary ball valve, sanitary butterfly valve not only have the adavantages of simple structure, small size, light weight, small material consumption, small installation size etc., but also have small driving torque, simple and rapid operation, and good flow regulation, sealing characteristics etc. When the butterfly valve is in the fully open position, the thickness of the disc is the only resistance when the medium flows through the valve body. So the pressure drop generated by butterfly valve is small, the valve has better flow control characteristics. In the food grade industry, sanitary butterfly valve is one of the largest and most common hygienic valve.
