Tideflex is a Division of the Red Valve Company

In 1984, the United States Environmental Protection Agency (EPA) commissioned Red Valve to develop and test an alternative to ineffective flap gate valves. As a result, the elastomer duckbill Tideflex Check Valve was specifically designed to eliminate operation and maintenance problems associated with flap gate valves - including corrosion, freezing open or shut, warping and clogging. The EPA tested the Tideflex Check Valve for two years and found that it showed significant improvement over flap gate valves in terms of leakage inflow, debris entrapment, self-cleaning and marine fouling. Today, hundreds of thousands of Tideflex Check Valves are installed and performing reliably worldwide. Tideflex Check Valves have become the world standard for maintenance-free backflow prevention.

Over the years, we have continued to enhance and refine the performance of our products. The custom-engineered design of the duckbill Tideflex Check Valve has led to other innovative applications such as potable water mixing systems, aeration and mixing systems, and effluent diffuser systems. The development of the Tideflex Mixing System (TMS) for water storage tank mixing led to a full line of NSF Certified check valves.

Tideflex Technologies has a full staff of professional engineers and designers that have developed specialized hydrodynamic models for use in the design of all Tideflex's systems. Our engineering team is ready to assist you in the design of unique and cost-effective solutions for difficult applications. Over thirty years of proven field operation, research and development, and continuous engineering enhancements have combined to make Tideflex Check Valves the most reliable duckbill Check Valves on the market today. When you specify a Tideflex Check Valve, you are guaranteed a product with a proven record of maintenance-free backflow prevention.
