CMU - CheckMate UltraFlex® In-Line Check Valve
CMU - CheckMate UltraFlex® In-Line Check Valve
Description
The CMU - CheckMate UltraFlex® In-Line Check Valve works by preventing unwanted backflow that can cause surcharging and flooding. The valve minimizes damage to commercial, wetlands, beaches and residential areas. It also eliminates hydraulic surges to wastewater treatment plants, saving municipalities millions of dollars in maintenance and treatment costs.
The CheckMate UltraFlex® has extremely low head loss and seals around debris. It operates completely on differential pressure, no outside energy source or operation is needed. Unlike other in-line check valves, the CheckMate UltraFlex® Valve contains no molded parts. It is hand-fabricated, utilizing multiple natural elastomers, synthetic elastomers, wire-reinforced plys and fabric-reinforced plys for a heavy-duty unibody construction. There are no mechanical parts or fasteners to catch debris, corrode or fail. This design makes the CheckMate® 100% maintenance-free and easy to install. With seven elastomers to select from, the CheckMate UltraFlex® Valve can be custom-engineered to resist chemicals, grease and oils typically found in stormwater, wastewater and industrial applications.
