Stainless Steel Ball Valve

The direction of the flow valve in the pipeline is mainly used to make cutting, changes in media distribution, it only needs to rotate 90 degrees rotation of the operation and a small torque can be closed tightly. The most suitable valve do switch, shut-off valve, V type ball valve. Electric valve should pay more attention to parameters of pipeline outside, still should pay special attention to the use of the environment condition, the electric device of electric valve is a mechanical and electrical equipment, the use of state by the use of great impact. Normally, electric ball valve, butterfly valve in the use of special attention should be paid to the following environment.
A; wear resistance; because the valve core and hard seal ball valve is alloy steel spray welding, sealing ring is alloy steel welding, so the hard seal ball valve does not produce wear too much in the switch. (coefficient of hardness of 65-70):
Two; the sealing property is good; because the sealing hard seal ball valve is the use of artificial grinding, until the spool and the sealing ring is completely consistent to use. Therefore, the sealing performance is reliable.
Three; the switch light; because the sealing ring at the bottom of the spring and hard seal ball valve of the sealing ring and the valve core clung together, so in the pre tightening force of outside forces over the spring switch is very light.
Four; the service life is long, has been widely used in petroleum, chemical, power generation, paper, nuclear energy, aviation, rockets and other departments, as well as people's daily life.
Pneumatic ball valve has the advantages of compact structure, reliable sealing, simple structure, easy maintenance, sealing surface and spherical often in the closed state, the media can not easily be eroded, easy operation and maintenance for water, solvents, acids, and natural gas general working media, mainly used for cut off or connected tube road of medium, can also be used for the regulation and control of fluid
