- 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.
