STRATE non-return valve RSK

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 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

The STRATE AWAaerob 110 - 1700 ventilation system consists of an oil-free compressor with noise suppressor, a switching system with operating hours counter and a timer, as well as a complete connection fittings set with manometer, check valve and connection line. The ventilation quantity and duration are adjusted by the timer based on the compressor run time. Fine pearls of oxygen are injected from the air. Ideal for short pressure pipes and high flow speeds in the pressure pipe Area of application for pressure pipes <= DN 200 Use with or without accompanying pipe (depending on the high and low points in the pressure pipe)

AVUSE-1 for degassing under pressure, AVUSE-3 for degassing, high flow rate air inlet and outlet. Simple but studied design – To reach the best performances with optimized components. Ventilation area protected – From splashes and clogging thanks to a specific deflector design, ensuring a long term operation. Polymeric high-quality material. Easy maintenance – Thanks to quick removal of the clamps and drainage cock.

The BEV-G is a single-stage valve offering only the function of the first ventilation stage (coarse ventilation) provided by the two-stage valve (BEV-GF). It is not necessary to coordinate the valve to the working pressure in the first ventilation stage, since coarse ventilation is always closed under pressure. Type G (coarse ventilation): The air escapes through this valve until the medium closes it as it continues to flow. The valve remains closed under operating pressure. Ventilation of individual sections in sloped pressure lines, especially as a low pressure safety feature Quick ventilation of high points if fine ventilation is not required (short pump run times)
