STRATE BEV-G for coarse ventilation

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.

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)

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.
