Technical description
TE BTF butterfly 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 medium can flow in one direction only. These butterfly valves are designed and manufactured to ensure maximum service life and reliability. They are mainly suitable for use in the power engineering, chemical and petrochemical industries, for liquids, gases and steam.
MATERIAL SPECIFICATION
Butterfly 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.
