GOYEN Since 1935, we have provided engineering expertise and partnerships to several of the world's leading dust collector manufacturers. Our diaphragm valves simply deliver the most powerful air pulses. These valves are specifically designed for baghouses in which reverse pulse jet systems, frequently clean the filters, including all bag filters, cartridge filters, envelope filters, ceramic filters, and sintered metal fiber filters. The rugged design and construction of our valves, and the resulting reliability, has led to their use in high-performance systems around the world. Dust collectors may be used to control the dispersion of noxious substances, improve indoor air quality in workplaces, or prevent harmful emissions.
