Sanitary plastic duckbill multi-position pass-through ball valve

    Sanitary plastic duckbill multi-position pass-through ball valve

    The sanitary plastic duckbill multi-position pass-through ball valve is designed for precise flow control and hygienic fluid transfer in food, beverage, pharmaceutical, and biotechnology pipelines. Constructed from high-quality, FDA-approved plastic, the valve features a duckbill design that ensures leak-free operation, multi-position flow control, and zero fluid retention. Its pass-through configuration supports easy cleaning, CIP (Clean-in-Place), and SIP (Sterilization-in-Place) processes, enhancing system hygiene. Lightweight, corrosion-resistant, and chemically stable, this valve offers d...

The duckbill multi-gear straight ball valve is a special valve that differs from ordinary ball valves in structure and working principle. This valve usually consists of parts such as valve body, valve seat, ball and stem, and has the function of multi-gear adjustment.


The ball of a duckbill multi-speed straight ball valve usually has a special shape and material to allow for better control of the flow of media when opening and closing. The design of its seat and stem has also been optimized to provide better sealing performance and adjustment capabilities.


This valve usually has multiple gears and can be adjusted according to different needs. By rotating the stem, the position and angle of the sphere can be changed, thereby controlling the flow and direction of the medium. This valve is suitable for applications where precise control of media flow and direction is required, such as chemical, petroleum, pharmaceutical, and other fields.


The duckbill multi-position straight ball valve is a powerful and easy-to-operate valve that can meet the fluid control needs of different fields. Its unique design and optimized performance make it an essential component in the field of fluid control.
