SILENT CHECK VALVES - 300/600 Series

Silent Check Valves are designed to prevent water hammer by positively closing before reversal of flow can occur. The valve closes silently, is low in cost, reliable and requires no regular maintenance. Silent Check Valves are commonly used in vertical turbine pump installations when pumping from a well to an elevated reservoir. They are also recommended for commercial and industrial HVAC applications such as heating systems and condensate return lines. When specified, the Silent Check Valves are Factory Mutual System Approved for use on hazardous fire fighting equipment and fire protection systems.
