Q (3 / 6 / 9) 47 (H / F) flanged fixed ball valve

Product Overview

Product usage:

It is used for medium pipelines of chemical industry, petroleum, natural gas, metallurgy, medicine, environmental protection, paper making, etc., and for cutting or connecting, as well as medium and high-pressure pipelines with particles, solids, slurry, etc.

Product features:

The fixed ball valve adopts the valve seat sealing structure in front of the ball. The two valve seats can independently cut off the medium at the inlet end and outlet end to realize the double blocking function. The valve seat is a movable valve seat cut by a spring. When the valve is closed, the valve seat will be pushed to the spherical surface together with the medium to ensure the sealing performance of the valve. When the valve is opened, the valve seat will return to the free state, greatly reducing the friction between the valve seat and the spherical surface, thus extending the service life of the valve.
