Applications

Butterfly valves can be actuated either manually or pneumatically. There is a wide range of manual controls to meet the different system requirements. Pneumatic controls can be horizontal and vertical, single-, double-effect, and modulating. They can be fitted with control tops and proximity It is widely applied to many fileds,such as beer,beverage,dairy food,fruit juice,pharmacy,biological etc.

Operatiing Principles

The butterfly calves 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 othe position available. The actuator push piston of axial movement into 90 degree so that it controls butterfly valve.
