Pneumatic ball valve for chemical dosing is a valve specifically designed for automated dosing of chemical agents, widely used in fields such as water treatment, pharmaceuticals, and chemical engineering. It achieves precise control through pneumatic actuators.
Core functions and features
Accurate measurement: It can be combined with flow meters or PLC systems to achieve quantitative dosing of drugs (with an error of ≤± 2%).
Corrosion resistant design: The valve body material is usually PPH, PVDF or 316L stainless steel, which is suitable for corrosive media such as acid and alkali.
Quick opening and closing: Pneumatic drive response time ≤ 1 second, suitable for dosing processes with frequent switching.
Sealing and leakage prevention: PTFE soft seal or metal hard seal is used to ensure that the drug does not leak.
Typical application scenarios
Water treatment system: control of the addition of PAC (polyaluminum chloride) and PAM (polyacrylamide).
Chemical process: Automatic proportioning of corrosive liquids such as sulfuric acid and sodium hypochlorite.
Pharmaceutical industry: High purity drug delivery in sterile environments.
