Inline Non-Return Valves
The WaStop Non-Return valve is designed to prevent back flow into pipeline systems, its design means it is un-obtrusive and vandal resistant.
It has numerous uses including tidal outfalls, sewer chambers and the protection of domestic properties. it can also be mounted in several different ways meaning it is a unique and very flexible method of preventing back flow.
The body tube is available in both 304L and 316L stainless steel dependant on the environment the valve is to be installed in. Standard sizes range from ø100mm to ø1000mm with larger sizes and specials available on request. The WaStop is available to withstand pressures of up to 8MwC and incorporates a chloroprene membrane. The membrane allows water to pass in the desired direction, however when water flows in the other direction the membrane is flooded, sealing the membrane against the inside of the stainless steel tube.
