6’’-16’’ Large-Diameter Electromagnetic Pulse Valves

  • Specially developed for the rotary blowing technology.
  • Advanced testing devices are provided.
  • Great flow capacity, small pressure loss, great blowing performance and long lifespan.
  • Complete specifications.Two structures for choices: one with a pulse valve body and the other without.
  • Great switching performance, reducing unnecessary air loss and cutting down the operating costs.
  • Large valve diaphragm components of different models may be customized.Larger valves can be used as substitutes for imported products, lifetime maintenance provided.
  • For each large valve, a pressure test was done and a test curve chart attached.
