Technical description
Ball valves K83 (with floating ball) are controlled, closing fittings. It closes or opens the flow of media through the operator from the outside, manually or installed drive. Ball taps allow the media to flow in both directions. They are designed in such a way that deposits limiting the functionality of the fitting are not formed in the flow channel. These taps are designed and manufactured to ensure maximum service life and reliability. They are particularly suitable for the chemical and petrochemical industries, liquids, gases and vapours.
MATERIAL SPECIFICATION
Ball valves are made from carbon and stainless steel. Material execution of ball valves can be selected according to the customer’s request so that it suits as much as possible valves service conditions.
