Technical description
KK conical plug 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 conical plug valves allow the medium to flow in both directions. These cone 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
Conical plug 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.
