Double Dosing Butterfly Valves

Double Dosing Butterfly Valves are a linkage metering device that integrates two sets of butterfly valves. Through the coordinated opening and closing and opening adjustment of the dual valves, it achieves precise medium proportioning or dual channel quantitative conveying. The structure is compact and the control accuracy is high.
2. Purpose
Widely used in industries such as chemical ingredients, water treatment dual agent dosing, and food and beverage mixing and blending, it is suitable for dual medium quantitative mixing and alternating conveying conditions to ensure precise and stable process proportioning.

Common Types

  • Manual linkage dual metering butterfly valve: The handwheel synchronously adjusts the opening of the dual valves, making it easy to operate and suitable for small flow proportioning scenarios
  • Electric linkage dual metering butterfly valve: motor-driven+intelligent feedback, high adjustment accuracy, compatible with automated proportioning system
  • Sanitary grade dual metering butterfly valve: mirror channel+quick connect, suitable for clean and quantitative conveying scenarios in food and pharmaceutical industries

Structural Advantages & Corresponding Benefits

  1. Synchronous linkage adjustment structur

  • Special point:  Dual stem coaxial linkage design, synchronous opening accuracy of ± 1%, clear calibration of adjustment scale
  • Result:The dual flow ratio is accurate, with small repeated measurement errors, meeting the high-precision ratio requirements

  1. Integrated valve group integrated structur

  • Special point:  Dual valve integrated casting, no dead corners in the flow channel, shared valve seat sealing
  • Result: Small installation space, reduced pipeline connection points, no leakage, easy maintenance
