STRATE sandwich-type non-return valves - SB

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

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.

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 AWALIFT 2/2x2 wastewater pumping system is suitable for towns with up to approx. 2800 residents. The system can achieve a discharge head of up to 120 mWS, thanks to the parallel operation of two pumps. An adapted, intelligent pump controller handles control, ensuring almost fault-free operation. Draining small towns with up to about 2800 residents which cannot be drained using natural gradient or as an intermediate pumping station within the context of a pressure drainage system Residential and industrial areas Towns Communities Infrastructure facilities such as airports, industrial parks, underground stations etc. Product features One holding tank with two separator systems 2 x 2 centrifugal pumps and motors according to type and operating location required Four pump gate valves Two STRATE non-return valves One Y-pipe DN 100 Two pressure pipe gate valves DN 100 Level measurement
