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.
