Three-piece welded low-temperature extended rod forged steel ball valve,extended rod forged steel ball valve, ball valve

The three-piece welded low-temperature extended stem forged steel ball valve DQ41F-40P is a type of valve in which the closing part is a ball that rotates around the centerline of the valve body to achieve opening and closing. Ball valves are used in pipelines to cut off, distribute and change the flow direction of the medium. The three-piece ball valve is a new type of valve that has been selected in recent years. This valve is generally installed horizontally.

one The fluid resistance is small, and its resistance coefficient is the same as that of a pipe section of the same length.

2. Simple structure, small volume and light weight.

3 The ball valve is tight and reliable. Nowadays, plastic is widely used as the sealing surface material of the ball valve, which has good sealing performance and has also been widely used in vacuum systems.

4. It is easy to operate and opens and closes quickly. It only needs to be rotated 90° from fully open to fully closed, which is convenient for remote control.

5. The ball valve is easy to repair. It has a simple structure and the sealing rings are usually movable, making disassembly and replacement relatively convenient.

6. When fully open or fully closed, the sealing surfaces of the ball and the valve seat are isolated from the medium. During the passage of the medium, it will not cause corrosion of the valve's sealing surfaces.

7. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be used from high vacuum to high pressure.

The working principle of the three-piece forged steel ball valve is to clear or block the valve by rotating the valve stem. Ball valves are easy to operate, small in size, can be made in large diameters, have reliable sealing, a simple structure, and are convenient to maintain. The sealing surface and the ball surface are often in a closed state, making them less prone to erosion by the medium. They are widely used in various industries
