Ball valve, the opening and closing element (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control, among which the hard sealed V-shaped ball valve has strong shear force between its V-shaped core and the metal valve seat of the welded hard alloy, especially suitable for media containing fibers, small solid particles, etc. The multi way ball valve on the pipeline can not only flexibly control the merging, splitting, and switching of the flow direction of the medium, but also close any channel to connect the other two channels. This type of valve should generally be installed horizontally in pipelines. Ball valves are divided into pneumatic ball valves, electric ball valves, and manual ball valves according to their driving methods.

Characteristics of ball valves:

1. Wear resistant; Due to the fact that the valve core of the hard sealed ball valve is made of alloy steel spray welded,
The sealing ring is made of alloy steel overlay, so the hard sealed ball valve will not experience significant wear during opening and closing. (Its hardness coefficient is 65-70):

2. Good sealing performance; Due to the fact that the sealing of hard sealed ball valves is manually ground until the valve core matches the sealing ring before use. So his sealing performance is reliable.

3. Light switch; Due to the use of a spring at the bottom of the sealing ring of the hard sealed ball valve to tightly hold the sealing ring and valve core together, the switch is very light when external forces exceed the pre tightening force of the spring.

4. Long service life: It has been widely used in various sectors such as petroleum, chemical, power generation, papermaking, atomic energy, aviation, rockets, as well as in people's daily lives.

Pneumatic ball valves have a simple and compact structure, reliable sealing, and easy maintenance. The sealing surface and spherical surface are often in a closed state, which is not easily eroded by the medium and is easy to operate and maintain. They are suitable for general working media such as water, solvents, acids, and natural gas. They are mainly used to cut off or connect media in pipelines, and can also be used for fluid regulation and control.
