Area of use
Due to their special design, 100 % free passage and low flow resistance, STRATE AWASTOP non-return valves are ideal for:
- Sewage technology, media with solids and coarse solids, sludge (up to 5 % TM)
- Fresh and service water technology, including in areas where high pressure losses make powerful pumps necessary
- On request: pumping of fluids deviating from the media listed
- Areas where quiet operation is particularly important
DN: 50 - 300

Coating Electrostatic plastic coating
Product features
- Non-return valves are recognised all over the world as for universal applications in the pumping of fresh water, effluent, sludge and air.
- Stand for high operational safety
- Stand out thanks to their excellent value-for-money and low maintenance requirements
- 100 % free passage
- Low flow resistance
- Quiet operation thanks to the inclined valve seat which shortens the closing distance
- Minimum clogging tendency through optimum hydraulic design− Fail-safe closing of the valve since the closing element is fixed securely into the valve cover
- Easy installation due to the screwless valve attachment for simple replacement of the closing element
- Leakproof even with low counterpressure
- Flow resistance (water, effluent)
- Pumping of liquid media with flow speeds up to 1.5 + 0.5 m/s
- Vertical installation position –upward direction of flow
- Horizontal installation position –inspection cover at the top; recommended installation position where there is a high solids share (e.g. sand, gravel, stones)
