Q (3 / 6 / 9) 41 (H / F) flanged floating ball valve
Product usage:
It is widely used in chemical industry, petroleum, electric power, liquefied gas, food, pharmaceutical, water supply and drainage and other fields
Product features:
The floating ball valve is one of the valves with good sealing performance. Because the ball is floating, when the valve is closed, the whole ball can be pushed to the sealing ring with the medium, and the cross-sectional area of the force is equal to the cross-sectional area of the drift diameter. Therefore, the sealing of this type of ball valve is relatively good, and the opening and closing speed of the valve is fast. The valve has reasonable design, light weight and convenient installation and transportation.
