Suzhou Xiechang Environmental Protection Technology Co., Ltd.
Pulse valves built by a factory
that's been doing this since 1992.
We specialize in pulse valves, pulse timers, filter bags, filter cages, venturis, connectors, and diaphragm kits for baghouse dust collectors — from a 50,000+ sqm manufacturing facility in Suzhou, China.
Who We Are
Three decades of dust-control engineering.
Founded in 1992 as Suzhou Xiechang Industrial Dust Collector Equipment Factory, we've grown into one of China's most recognized manufacturers of pulse jet valve systems. Today our 50,000+ sqm Suzhou campus designs, tests, and ships more than 60,000 valves per month to customers on every continent.
