Characteristics of ball valve
One; wear resistance; because the valve core is hard sealing alloy steel spray welding,
Ring is alloy steel welding, so the hard sealing ball in the switch will not produce too much wear. (its hardness is 65-70):
Two; good sealing performance; due to the sealing of the hard sealing valve is the use of artificial grinding, until the valve core and sealing ring can be used completely. So his sealing performance is reliable.
Three; switch light; due to the sealing ring at the bottom of the sealing ring with a spring, the sealing ring and the valve spool tightly together, so the outside force is more than the spring preload, the switch is very light.
Four; long life: has been widely used in oil, chemical, power generation, paper, nuclear energy, aviation, rockets and other departments, as well as people's daily life.
Pneumatic ball valve compact structure, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, is not easy to be medium erosion, easy operation and maintenance, suitable for water, solvents, acids and natural gas and other general working media, mainly used for cutting off or connected to the media, can also be used for fluid regulation and control.
