Stainless Steel Ball Valve
Our stainless steel ball valve works as an on/off valve and throttling valve for pipelines. Both unibody ball valves and split-body ball valves are available.
Advantage
This water control valve is characterized by its simple structure, small size and light weight. Its fluid resistance is also extremely small, equal to that of pipe of the same length.
Our stainless steel ball valve allows convenient operations and maintenance. It needs only a quarter turn to change its position from fully open to fully closed, and its simple structure and movable seal ring easily facilitate replacement.
The sealing surface between the valve ball and valve seat is made from plastic in order to offer excellent leak tightness. It is isolated from the flowing media when the valve is fully open or fully closed, which avoids corrosion on the sealing surface.
The stainless steel ball valve is available in a series of specifications suitable for different applications. For example, it can work with pipes that range in diameter from a few millimeters to several meters, and it performs well under high vacuum or high pressure conditions.
