DS (3 / 6 / 9) 73h wafer type three eccentric two-way sealing butterfly valve

Product Overview

explain:

The wafer type two-way hard seal butterfly valve is a new butterfly valve newly developed by our company in combination with the market demand, using SW, CAD and other software aided design, continuous innovation and improvement of processing technology.

purpose:

The two-way sealing butterfly valve is mainly used in petroleum, chemical industry, power station, metallurgy, paper making, plumbing, light industry and other fields as a device for cutting off and regulating pipelines.

Product features:

The wafer type two-way pressure bearing butterfly valve of our company adopts a three eccentric and movable valve seat structure, so that there is no friction between the butterfly plate and the sealing pair when opening and closing, which effectively ensures the sealing performance when reverse pressure is applied. The valve has compact structure, light weight and convenient maintenance.
