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

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.

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 special lightweight aluminium design and silicone inserts of STRATE sandwich non-return valves SB makes them ideal for: Conveying air and gases up to temperatures of 200 °C Working pressures up to 4 bar Special applications with other valve insert materials on request

Explosion proof safety valve to protect inbreathing openings of storage tanks, vessels and pipes to prevent inordinate vacuum. Approved for flammable liquids of explosion group IIB3 with a maximum experimental safe gap (MESG) ≥ 0.65 mm and a Maximum operating temperature of 60 °C.

Application as inline armature with venting or breather valve function for vessels. Preferably used for installation in pipes. Depending on the installation, the valve can be used as pressure or vacuum valve. It can also be used as non-return safety device or overflow valve.

The Hartmann pig valve provides a space- and cost-saving substitution for expensive pig launching systems. In addition to its classic use as shut-off valve, it functions as pig launcher or receiver. The simple, secure, and fast insertion or removal of scrapers take place through an interlock that is integrated on the side of the valve and locked and secured through a bayonet system. An optional bypass in the closed position also allows cleaning operations when the medium flow is not to be interrupted completely. Also separating different products in a pipeline is possible. A 3-step, redundant safety concept and an entirely metallic sealing shut-off guarantee highest availability for operation and cleaning of oil, gas, slurry and water applications. Special designs are available: e.g. 180° pigging valves which can act as launcher and receiver in both directions, or pig valves for extended scraper lengths than the standard 1.4 x nominal diameter of the pipeline.

The Hartmann Twin Ball Valve (TBV) provides a double line barrier and enables a significant increase of safety without much effort. Designed for applications with especially high safety requirements, the TBV consists of two integrated ball valves, which can be equipped with two independent barriers each. Thereby the safety can be raised by factor 4 compared to a standard valve. With the Double Isolation and Bleed function each ball valve seals both at the upstream and downstream side. With the so-called „studded“-design, meaning a closed flange form, the valve has the length of a single standard valve and affords a compact and economic alternative for the application of multiple valves. The TBV comprises – like all Hartmann valves – a pure metal-to-metal sealing system between ball and seat ring. With this sealing system leakage rates A, respectively 0, can be fulfilled. Furthermore, it is characterized by an outstanding longevity and low maintenance requirements.
