BUTTERFLY VALVE WITH ROTARY ACTUATOR

HOME/BUTTERFLY VALVE WITH ROTARY ACTUATOR

BUTTERFLY VALVE WITH ROTARY ACTUATOR – SERIES 232

Pneucon Double Offset Butterfly Valve design is the most common type of rotary valve and provides low weight to Cv Ratio, Combined with simplicity of design and comparatively low cost. It is simple device to control or block the flow. A single vane or wafer disc pivots in the Valve Body and find wide application for throttling or two position control in the chemical, paper & pulp, sugar Industries, cooling water circulation, water treatment Plants, compressed air, gas plant, flue gas desulphurization plants etc.
