Our check valves have application, for flood prevention, backflow control and even odor control.
Its main characteristics:
Red Valve is more than 60 years old, providing valves and engineering systems of the highest quality backed by technical innovation and customer service.
CheckMate® in-line check valve is based on the experience and development of elastomer technology from our Tideflex® line, one of the most well-known valves proven to provide reliable prevention of long-term backflow throughout the world.
In 1984, the United States Environmental Protection Agency (EPA) instructed Red Valve Company to develop and test an alternative to tidal gate valves. In its report, Development and Evaluation of a “Duck Bill” Rubber Tide Gate, the EPA states:
“The increased reliability and performance of tidal gates has a beneficial impact on the overall pollution reduction program for the nation’s waterways.”
In response, Red Valve Company developed and patented its “duckbill” Tideflex® elastomer check valve to eliminate the operational and maintenance issues associated with flapgate check valves, including mechanical parts corrosion, open or closed freezing, deformation and obstruction due to trapped debris.
EPA rigorously evaluated the Tideflex® check valve for two years and discovered that the valve showed:
“A significant improvement over gate valves in terms of leakage entry, debris entrapment, self-cleaning capability and susceptibility to marine fouling.”
Since the creation of the Tideflex® check valve in 1984, years of research and development, testing and proven performance have led to the globalization of the Tideflex® TF-2 check valve and the next generation of Tideflex® TF-1. With improved flow efficiency features and the latest technology in elastomers. The name Tideflex® is respected and recognized throughout the world as the most reliable valve for the prevention of reflux. Since the first Tideflex® check valve installed in 1984, it is still in service today, with more than 800,000 Tideflex® check valves in service worldwide, which reliably resolve seal and jam problems.
Problem: Traditional gate valves block and allow millions of gallons of water to return to treatment systems or plants to re-treat or cause flooding in cities.
The Tideflex® check valve eliminates the problems of gate valves in terms of leakage entry, debris trapping, lack of self-cleaning capability and susceptibility to marine fouling.
Proven performance has revolutionized the prevention of fluid return
Solution: The forward hydraulic pressure opens the valve to allow the flow, and the reverse pressure seals the valve preventing the back flow. Each Tideflex® and CheckMate® Valve are custom built for each application.
The Duckbill type valve
The principle of operation of the Tideflex duck bill opens with positive pressure, starting from 1″ WC allowing the passage of the flow.
The return pressure seals the peak of the Tideflex check valve, stopping the flow from the opposite direction. The counterflow is prevented.
The advantages presented by Tideflex are the following:
