Product Description

The floating ball valve is a kind of common product in the industry. Especially provided for the condition with low and middle pressure.This ball valve is applicable for water, oil, steam and other corrosive mediums.
 

Benefits

Features

1.Manufactured with full bore or reduce bore structure, the one-piece floating ball valve, two-piece floating ball valve and three-piece floating ball valve are all available.
2.The floating structure makes the ball press on the sealing surface due to the displacement caused by the pressure of the medium. Therefore, our floating ball valve has good sealing performance.
3.The valve stem of the manual ball valve is offered with blow-out proof structure.
4.In case there is fire, the electric floating ball valve is still reliable for use due to the fireproof structure of the valve.
5.To avoid the accumulation of the static, this range of valve is provided with anti-static structure. The spring plunger type static extraction device forms the static access between the ball and the stem and valve body and stem to avoid the accumulation of the static.
