Rotary valves are tested and certified to comply with NFPA-69. Completed testing at a “knowledgeable test authority” certifies the valve complies with NFPA-69 rotary valve design criteria. Testing showed the valve to exceed the required testing pressure of 1 barg and withstood deflagration pressures up to 2.3 barg. Besides compliance with NFPA 69, the valves are also an economical and cost-effective tool for creating an airlock between dust collectors and the collection containers. P Lastly, a direct drive motor eliminates the hassle and maintenance of dealing with belts.
