Applications

QF7 sanitary butterfly-ball valve is an automatically or manually operated sanitary butterfly valve. It's suited for various applications in stainless steel pipe systems. It is the best choice for treating viscous medium or medium containing particulate substance in the sanitary industries. It is mainly used in food, beverage, pharmaceutical and chemical industries.

Operating Principle
QF7 sanitary butterfly-ball valve can be manually operated by a handle or remote controlled by an actuator. It is characterized by simple structure and easy disassembly as butterfly valve. Meanwhile, it features less resistance, flexible opening and closing, wide application range and long lifetime. With the design of drainage device, the problem of medium remaining is reduced, which is very common in ordinary ball valves.
