BUTTERFLY VALVES
BUTTERFLY VALVES
The VCL Butterfly Valves are used to shut-off or control gas streams in pipelines. They are installed in many kinds of installations and used in different industries, e.g. Iron & Steel, Non-Ferrous, Glass or Petrochemical. Due to the easy construction method and the rotation axis in its center, butterfly valves can be used in any pipeline orientation. Butterfly valves are commonly used either for regulation of flow and pressure or for shut-off purpose without requirement in regard of tightness, e.g. in upstream direction of a Goggle Valve to minimize the flow during operation.
