Dosing Burerfly Valve

Dosing Butterfly Valve is a butterfly valve that combines on/off and precise flow regulation functions. It controls the medium delivery rate by fine-tuning the butterfly plate opening. With a compact structure and high adjustment accuracy, it is a specialized control component for industrial quantitative feeding and dosing systems.Widely used in industries such as water treatment dosing, chemical ingredients, food and beverage quantitative filling, pharmaceutical preparations, etc., it is used for precise metering and transportation of acid-base solutions, pharmaceuticals, raw material slurries and other media, suitable for small flow, high-precision quantitative feeding conditions, and ensures stable process proportioning.

Common Types

  • Manual adjustment of metering butterfly valve: handwheel scale adjustment, intuitive operation, suitable for low-frequency and small-scale flow regulation scenarios
  • Electric regulating metering butterfly valve: motor-driven+scale feedback, high adjustment accuracy, can be remotely controlled, compatible with automated dosing systems
  • Pneumatic regulating metering butterfly valve: driven by pneumatic actuator, fast response, good explosion-proof performance, suitable for chemical explosion-proof working conditions
  • Sanitary grade metering butterfly valve: mirror polished flow channel, quick connect, suitable for clean and quantitative conveying scenarios in food and pharmaceutical industries

Structural Advantages & Corresponding Benefits

  1. Scale type butterfly plate positioning structure

  • Special point: The butterfly plate is equipped with a precise scale positioning pin, with an opening adjustment accuracy of ± 1 °, and the valve stem is rigidly connected to the butterfly plate without any gap
  • Result:The flow control is precise and stable, with small repeated measurement errors, meeting the high-precision requirements of process proportioning

  1. Low flow resistance streamlined flow channel structure

  • Special point:  Polishing of the inner wall of the flow channel, rounded transition of the butterfly plate edge, and tight fitting of the sealing surface without dead corners
  • Result: The medium has no residue, prevents scaling and blockage, and is suitable for quantitative transportation of viscous and granular agents
