Handle pair butterfly valve is mainly composed of valve body, stem, disc and sealing ring. The valve body is cylindrical with short axial length and built-in disc.
The quickening pace of valve industry restructuring, the future industry will be the valve product quality and product competition between brands, products to high technology, high parameter, strong corrosion resistance, high life direction, it is only through constant technical innovation, develop new products, technical renovation, in order to gradually improve the level of product technology, meet the equipments at home and abroad, fully realize the globalization of the valve.
