Tideflex® Effluent Diffuser Valves, from the Red Valve Company Inc. (Carnegie, Pennsylvania, USA), with an all-elastomer Duckbill® design, prevent intrusion of saltwater and sediment into a marine outfall system and keep the outfall operating at peak hydraulic capacity and dilution efficiency. The valves can be installed in new outfall systems or retrofitted to existing pipelines on diffusers that discharge to oceans, estuaries and bays, which face severe clogging problems due to strong currents, waves, tides, sediment transport and boat traffic. The Tideflex® valves are described in a free brochure that Red Valve has just published.
