Technical description
TE BTF butterfly valves (WHP) are controlled, shut-off valves. They close or open the flow of medium by an external operator, manually or by an installed actuator. The medium can only flow in one direction. These shut-off dampers are designed and manufactured to ensure maximum durability and reliability. They are particularly suitable for the energy, chemical and petrochemical industries, for liquids, gases and vapors.
MATERIAL SPECIFICATION
Butterfly valves are made from carbon, alloy and stainless steels. The material design can be adapted to the customer’s wishes to best suit the operating conditions.
