Product Category

SQ (3 / 6 / 9) 47 (H / F) flange mounted fixed ball valve

Product Overview

Product usage:


It is widely used in: chemical industry, petrochemical industry, petroleum, paper making, mining, power, liquefied gas, food, pharmacy, water supply and drainage, urban construction and other fields.

Product features:

The valve body of the top mounted ball valve is of integral design, which will not affect the use of our valve due to the expansion and contraction of the pipeline. The ball and the valve seat are of top mounted structure, and it is not necessary to remove the valve from the pipeline when repairing the valve. The ball and the valve stem can be integrated, effectively solving the machining gap between the valve stem and the ball, ensuring the precise positioning of the ball and the protective structure against blowing out of the valve stem. The sealing form of the valve stem and bonnet is not the ordinary packing seal, but the packing box combination seal. The ball and valve seat can adopt ppl or metal hard seal according to customer requirements.
