Rubber flap check valve
The Rubber Flap Check Valve is engineered for efficient backflow prevention in systems handling water, sewage, gas, oil, and certain chemicals. Its streamlined design features a single moving part—the flexible rubber flap—which ensures low head loss and resistance to clogging. The valve's 45-degree seat angle and 35-degree disc travel facilitate rapid closure, effectively minimizing water hammer effects.
Key Features:
-
Full 100% flow area for minimal pressure drop.
-
Non-slam operation due to short disc travel.
-
Reinforced rubber flap with integral O-ring ensures tight sealing under varying pressures.
-
Simple structure allows for easy maintenance and long service life.
-
Versatile applications: Suitable for water supply and drainage, sewage treatment, and industrial processes.
