Product Details

Description

This double flange butterfly valve has the features of compact and light structure, long wear-resistant sealing life, easy installation and maintenance.It is mainly used in water plant, power plant, steel plant smelting, chemical industry, water source engineering, environmental facility construction and other systems for drainage, especially for the use of water channel and road as regulating and intercepting equipment. Compared with the center line butterfly valve, the double handle butterfly valve is more resistant to high pressure, which has longer life and better stability.
