STRATE AWASTOP non-return valve

The STRATE non-return valve RKS is particularly suitable in areas where the prevention of flap impacts is of particular importance. In this application case the extension of the standard butterfly valve RSK by the additional component STRATE spring load (RSK-FT or RSK-FTU) is required Product features (STRATE RSK) Wide flap to prevent piercing, especially at high pressure levels Type RSK-FT: Equipped with exterior spring load to more quickly close the flap and avoid flap impact Type RSK-UD: Bypass line with pressure shock damping valve to reduce/avoid pressure shocks Type FTUD: a combination of the above types to optimally protect the pumps in case of a power outage, etc.

Pre-fabricated STRATE AWASTATION service buildings are set up directly on top of shafts (STRATE AWALIFTSCHACHT) or optionally alongside shafts on concrete foundation blocks. Pre-fabricated solutions offer the possibility of housing system components e.g. shaft cabinets, control elements, electric systems and service connection so that they are easily accessible integrating further optional system components e.g. STRATE AWAaerob ventilation systems, operating data recording and remote transmission etc. One-piece pre-fabricated concrete building, suitable for road and crane transport with four threaded attachment and transport sleeves Re-siting of the service building is possible Inside walls: exposed concrete, painted with washable dispersion paint, colour according to customer wishes Outside walls: textured render, painted in colour according to customer wishes Floor: smooth concrete floor plate with openings for shaft cover, cable duct etc.

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.
