What are the salient features of a ball valve

Ball valves are used for fluid regulation  control, in which the hard-sealed V ball valve has a strong shear force between its V ball core  the metal seat of hard alloy surfacing, especially suitable for media containing fibers, tiny solid materials, etc. .. Here are some prominent features:

Wear; since the ball valve body is sprayed steel, the alloy steel welds the ring so that the ball will  have as much wear during switching. The upper limit of the flow volume of the electric cut-off ball valve: due to its streamlined line  full quarter-turn control, the upper limit of the volume is particularly high, the flow capacity is particularly large,  the flow resistance is small, so a smaller  more economical valve can be used. size. Pneumatic knife gate valve is a quarter-turn control valve, which is used in conjunction with a valve positioner. Pneumatic cut-off valve upper limit reliability: the valve body is an integral structure, sturdy  durable, the operation is  affected by the pipeline pressure,  the leakage of the valve body can be avoided. (65-70  its hardness coefficient):

Second, the sealing performance is good; because the sealing of the ball valve is carried out by traditional manual grinding, the enterprise can only use it until the valve core  the sealing ring can be completely matched. So his sealing system performance is reliable.

Third, the switch is light; since the bottom of the ball valve uses a spring to make the sealing ring closely fit the valve core, when the external force exceeds the spring preload, the switch is very light..

Fourth, long life: each sector has been widely used in petroleum, chemical industry, power generation, papermaking, nuclear energy, aviation, rockets, etc., as well as people's daily life.
