Series WaStop® - Check Valves

Check up to five results to perform an action.

  • No mechanical parts
  • Stops the migration of dangerous sewer gases into living spaces or other occupied areas
  • Responds to very low inlet pressures
  • Self cleaning - minimal maintenance, completely smooth lower pipe.
  • Simple installation, even in existing pipes and chambers
  • Protects against flooding

    The WaStop® low pressure check valve consists of two parts, the polyurethane sleeve and the pipe. The pipe is supplied with 304 stainless steel and is also available with 316 SS or plastic for specific applications. The sleeve simply folds up and out of the way with very little inlet pressure to allow the flow to pass through the valve.  Inversely the sleeve is capable of resisting several metres of pressure in the opposite direction.

    Dimensions DN 110-1200 can be manufactured in plastic, with or without flange.
