Why is the sales volume of Sanitary Ball Valve getting better and better?

Direct-welded sanitary ball valves are suitable for underground facilities, offshore platforms and submarine equipment. Direct-welded ball valves use high-quality forged parts, which are integrated into one piece through single-layer welding in the middle part of the valve, making the shape of the valve closer to a spherical shape, and the structure of the valve is more compact, lighter and stronger. Single-layer direct welding can also achieve high-precision valve manufacturing, so that the valve seat and the ball can be fully sealed. The valve body design that is fully welded without bolting completely eliminates external leakage. At the same time, this type of ball valve adopts a fireproof structure design and does not require any maintenance.

The sanitary ball valve series track ball valve is a multi-turn ball valve that uses the principle of tilting and rotating to eliminate scratches on the sealing surface. When the valve is closed, the ball core is mechanically pressed onto the sealing valve seat, ensuring a tight seal without the help of pressure difference; when the valve is opened, the ball core tilts away from the valve seat, and the fluid in the pipeline passes through the valve evenly along the surface of the ball core at 360 degrees, eliminating the local erosion and corrosion of the valve seat by high-speed fluid. Since there is no friction when the valve is opened and closed, the operation is light and reliable.
