PTFE lined centric butterfly valves – BIANCA InterApp

Main Futures:
Centric “Butterfly” valves are used for ON/OFF and flow regulation. Their principle of operation (opening and closing a quarter turn by means of a disk mounted on an axle) resembles that of ball valves, but their main advantages over them are lower cost and less weight, which eliminates the possible need for additional installation on supports.

Type of body:
Wafer – between flanges.

Lug – between flanges with threaded LUGs. It is ALSO possible to dismantle the pipeline from one side without the need to remove the valve itself.
