Technical description
S43 gate valves are high-pressure, 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 medium can flow in both directions. They are specially designed for use in the power engineering, chemical and petrochemical industries, for liquids, gases and steam.
MATERIAL SPECIFICATION
Gate 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.
