Pneumatic Butterfly Valve

Description

Three-piece butterfly valve with pneumatic head

Butterfly Valves

Applications

Butterfly valves, no matter manually or automatically, can be used in most fluid product applications in the food一processing, pharmaceutical and chemical industries.

Operating principles

·The butterfly valves can be operated automatically through actuator or manually with the handle.

·The handle blocks the valve in the ‘open’ or ‘closed’ position,certainly there are the other position available.

·The actuator push piston of axial movement into 90 degree so that it controls butterfly valve.
