Ball valve

Ball valves are evolved from the rotary valve. It has the same rotated 90 degrees, and different is that the cock body is a sphere, by round holes, or channels through its axis.

Spherical and proportion of openings should be such, that when the ball is rotated 90 degrees, at the inlet and outlet should be spherical, thus truncating the flow.

Ball valve requires only 90 degrees of action and very little driving refused, you can close tightly. Safety valve cavity of the equality, offers very little resistance, through the medium of the flow channel.

Generally considered most suitable for use by direct opening and closing the ball valve, but with the recent development of ball valves have been designed, so that he has the throttle and control the flow of.

Main characteristics of ball valve is itself compact structure, easy to operate and maintain, and suitable for water and gas, solvents, acids and other general media, but also to poor working conditions of media such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve can be whole, or they can be combined.
