K84

TECHNICAL DESCRIPTION

K84 (floating seats and trunnion mounted ball) valves are controlled shut-off valves. They are designed to stop or allow the flow of the medium by external operation, either manually or via the installed drive. The ball valves allow the medium to flow in both directions. Their construction is designed to prevent the build-up of sediment in the flow channel which would otherwise hinder the valve operation. These ball valves are designed and manufactured to ensure maximum service life and reliability. They are mainly suitable for chemicals and petrochemicals, liquids, gases and steam.

MATERIAL SPECIFICATION

Ball valves are made from carbon and stainless steel. The material type can be adjusted according to the customer´s request to optimally suit the operating conditions.
