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. Housing:EN-JL1040, 1.0116 Coating:TPE, EGD

Elastische Kugeln werden vorwiegend als Verschluss in Ventilen und Pumpen, in Rohrleitungen und Heizungssystemen, als Molche für die Rohrreinigung oder als Reinigungskugeln in Siebanlagen verwendet. Ventile gehören zu den bekanntesten Absperrorganen und verhindern ungewollten Rückfluss von Gasen, Flüssigkeiten oder körnigen Stoffen und Stäuben. Im Käfig der Kugelventile liegt die frei bewegliche elastische Kugel und wird durch das einströmende Medium aus dem Ventilsitz gehoben. Bei Rückfluss wird sie durch Kraft und Eigengewicht wieder in den harten Ventilsitz gepresst und dichtet dadurch ab. Der Ventilsitz sollte dem für die Ventilkugel verwendeten Werkstoff angepasst sein. Für viele spezifische Einsatzbedingungen stehen uns entsprechende Werkstoffe aus Elastomeren und Kunststoffen zur Verfügung. Neben den Standardabmessungen können wir Zwischengrößen mit umfangreichen Werkzeugpark abdecken.

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 Housing:fibreglass plastic (GRP)

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. Housing:EN-GJL-250 (GG 25) Coating:Acrylic combination paint

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. Housing:EN-JS1030, 1.0038 Coating:EGD

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 Housing:fibreglass plastic (GRP)

Positive displacement blowers and single-stage screw compressors start up directly or following a star delta circuit if no gentle start or no frequency converter control are available. The unit is subjected to heavy mechanical load and requires high start-up current. For this reason, counterpressure must be reduced during the start-up phase; this is achieved by blowing off the increasing volume flow. The fully automatic medium-controlled STRATE relief valve EVA has been specially designed for this procedure. As well as not requiring any maintenance, the STRATE relief valve EVA is an extremely economical device for reducing load during start-up since there is no longer any need to use complex externally controlled valves or electronic start-up aids. Product features Fully automatic control Specialized material G-AISi9Cu3 - specific to the requirements With solenoid valve for different motor speeds With overpressure valve For higher pressures and temperatures
