Dt673H pneumatic metal sealing butterfly valve, use an “U”-type stainless steel sealing ring, the ring touch three-dimensional eccentric of butterfly valve, isolated sealing surfaces when butterfly plate open, closed to sealing, extend using life, good sealing. So widely used in media(temperature≤550℃), like metallurgy, power, petroleum, chemical, air, gas, fire gas and corrosive media of pipes, for regulating flow and cutting off fluid

Features

1、  simple structure, impact, light weight, easy to install and uninstall, convenient maintenance

2、  use stainless steel “U”-type sealing ring, with flexible performance whatever under high temperature or low temperature

3、  the distance of three-dimensional eccentric, through rigorous calculation, no friction between “U”-type sealing ring and butterfly plate, long using life

4、  sealing surface of valve plate use Co-based cemented carbide hardfacing, wear resistance, long using life

5、  special structure, “on-off” just need to rotate valve stem 90°, flexible operation, convenient, effort, not affected by media pressure, reliable sealing

6、  high temperature resistance, low temperature resistance, corrosion resistance
