STRATE TECHNOLOGIE FÜR ABWASSER GMBH

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.

Two-stage ventilation valve for release rates of 450 to 2000 m3/h in coarse and 20-40 m3/h in fine ventilation. For DN 80 and 100 housing material: EN-GJS-400-15, coating EKB; for DN 150 housing material S235 JR or P355 T1 and the coating consists of a wastewater-resistant Permacore thick micaceous iron ore coating First, air escapes during the first stage (coarse ventilation), until the medium closes off the first stage as it continues to flow. Any remaining air then escapes more slowly through the second stage (fine ventilation), until it is also closed. Gases collect, causing the fine ventilation to open once again until the medium closes this stage as well as it continues to flow.

The BEV-F is a single-stage valve offering only the function of the second ventilation stage (fine ventilation) provided by the two-stage valve (BEV-GF). For ventilation quantities of 20 to 40 m3/h. Specific applications include high points which are under hydrostatic pressure even when the pump is shut down due to the height variation involved, and where no coarse ventilation is required, as well as at high points with low flow quantities. Type F (fine ventilation): Air escapes through this valve, and collected gases cause it to open once again, including under operating pressure, until the medium continues to flow and close the valve again. Installed at high points which are under hydrostatic pressure even when the pump is shut down due to the height variation involved, and where no coarse ventilation is required. Installed at high points of pressure lines with low flow quantities.

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)

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 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)

Compressed air flushing surge after a pumping stage has been completed. Product features Ideally suited for longer pressure pipes with several high and low points and longer rising or falling sections Mixes oxygen from the air very thoroughly with the sewage Prevents formation of biofilm in the pressure pipe (reduces thickness of biofilm, leads to biofilm tearing) Area of application for pressure pipes <= DN 200 Ideal for existing pressure pipes, an accompanying pipe is not require

Purging the pipe Product features Preferred use in systems which allow the economic emptying or partial emptying of the pressure pipe or in systems into which sewage is not discharged all year round, making emptying of the pressure pipe sensible e.g. on campsites (high/low season) For systems where high and low points are not very pronounced Can be used when small air pockets can be present in the pressure pipe without affecting the pumping capacity or the pressure pipe itself An accompanying pipe is not required

STRATE valve shafts are used in industrial and municipal areas. The different design sizes of the STRATE AWALIFT valve shafts allow the optimum size to be assigned to every individual purpose. Pipe and cable ducts, which are located exactly according to customer specifications in the manufacturing plant, meet all requirements for an exact fit, safety and ease of maintenance. Optimum, safe installation locations for valves and system components whose size allows them to be housed in a shaft Are excellently suitable as inspection shafts with flushing connection, as feeding points for AWAaerob ventilation systems, for ventilation and bleeding valves, for pig traps etc. Are made of high-quality, durable and waterproof materials with a high material strength and low material weight, with the design permitting short installation times and excluding complex

STRATE AWALIFTSCHACHT pre-fabricated shafts are used in private, industrial and municipal areas where the installation of sewage pumping stations within existing or planned buildings is not possible. The different design sizes of the pre-fabricated STRATE AWALIFT shafts allow the optimum size to be assigned to every individual AWALIFT pumping station. The possible installation of basement draining pumps in pump sumps is taken into consideration in the shaft dimensions. One-piece compound structure made of glass fibre reinforced plastic (GRP) from a shaft pipe diameter of 1000 mm to 2900 mm, cover and base plate made of reinforced concrete. Absolute water-tightness provides for excellent suitability for further purposes e.g. as an inspection, cleaning or valve shaft. Meets all the requirements of the ATV “Sewage” regulations, which means the pre-fabricated STRATE AWALIFTSCHACHT complies in production and scope of supply completely
