One; wear; as a result of hard seal ball valve is alloy steel spray welding,
The sealing ring is alloy steel surfacing, so the hard seal ball valve in the switch will not produce too much wear. (Its hardness factor is 65-70):
Two; sealing performance; due to the seal of the hard seal ball valve is used artificial grinding, until the spool and seal ring can be used in order to fully use. So his sealing performance is reliable.
Three; switch light; as a result of hard seal ball valve ring at the bottom of the spring so that the seal ring and the spool firmly together, so the outside force exceeds the spring preload when the switch is very light.
Four; long life: has been widely used in petroleum, chemical, power generation, paper, atomic energy, aviation, rockets and other departments, as well as people's daily lives.
Pneumatic ball valve compact structure, reliable sealing, simple structure, easy maintenance, sealing surface and the spherical surface is often closed, not easily eroded by the media, easy to operate and maintenance for water, solvents, acids and natural gas and other general working medium, In the cut-off or connected to the pipeline in the medium, can also be used for fluid regulation and control.
