Product overview
The flange stop valve relies on the valve stem pressure to closely combine the sealing surface of the valve disc with the sealing surface of the valve seat to prevent the medium from flowing. In the process of opening and closing, the sealing surfaces have the characteristics of small friction, wear resistance, small opening height and good manufacturing process performance. It is the most widely used valve in the industrial sector.
Product features
The structure of the stop valve is simple, and the manufacture and maintenance are convenient;
The sealing surface is not easy to wear and scratch, with good sealing performance and long service life;
When opening and closing, the valve disc stroke is small and the opening and closing time is short.
