PRODUCT OVERVIEW
Manual flange diaphragm valve is a special type of valve with cut-off function. Its opening and closing parts are composed of diaphragm made of steel disc and soft material (rubber and fluoroplastic composite), and separate the inner cavity of valve body from the inner cavity of valve cover, so as to cut off the medium in the pipe. It is widely used in urban construction, chemical industry, metallurgy, petroleum, pharmacy, food, beverage and environmental protection.
