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.
