800mm Inline Non Return Valve for 800mm internal diameter pipework.

800mm WaStop valves are inline backflow and flood prevention valves. WaStop inline non return valves (NRV) are made up of either a stainless steel grade 304 or 316 incorporating a cone-shaped chloroprene membrane. The membrane allows flow to pass in the desired direction but when backflow occurs the membrane fills out and seals the pipe.

  • Lowest headloss amongst inline check valves
  • Easy installation saving costs on contraction and installation
  • In-built automatic pulsating flow mechanism
