Security by Monitoring - AWH Butterfly Valves with RFID Transponder

The RFID transponder can be found today in almost all areas of daily life. We make use of this standard of technology and now implement RFID transponders in our butterfly valves. Read all relevant data directly on the valve. A special in-metal transponder stores all relevant data on the valve. The information can be updated or overwritten up to 10,000 times. You can save inspection intervals, item numbers, type of sealing, order numbers and further data in the memory. The transponder can be retrofitted, is water proof and immediately ready for use. Each transponder is unique as it has an ID number that cannot be overwritten. They can also store the item number from their P&ID on the chip. This means that the chip and valve can be assigned again and again.

This type of monitoring gives them increased security in dealing with their systems and processes. There are particularly robust devices with easy-to-read displays for reading and writing transponders, especially for applications in plants and production facilities. All data can be transferred from the mobile device to your system via bluetooth, for example. 

TANKO-MX150 - the newest member of TANKO family.

The design-protected TANKO-MX150 is a medium driven jet cleaner with controlled rotation. The device is used in a wide range of industrial applications where vessel and tanks need high impact cleaning. Due to a compact design the TANKO-MX150-G14 (4 nozzles) has a minimum insertion requirement of 150 mm diameter while the TANKO-MX150-G12 (2 nozzles) requires an opening of just 115 mm diameter.

The 360° spray pattern cleaning is based on 4 or 2 nozzles. The device has plain bearings and a planetary gear system. It has been designed to produce the best cleaning results. It is self-cleaning, works with high impact and still has impressively low consumption figures.

Pneumatic Sampling Valve

With the hygienic, pneumatic compact air sampling valve, there is also an automatic sampling system with additional manual actuation in the AWH portfolio. The sampling valve has a clamp connection in accordance with DIN 32676 and is compatible with the AWH Connect tank connection flange system. Our design is based on the tried-and-tested hygienic sampling valve with manual operation. Upon request, an optional flushing connection can be attached for this version. This means that a connection to an automated CIP/SIP system is possible. In addition to the various predefined versions in the AWH sampling portfolio, customer-specific solutions can also be implemented.


Spate Cleaner TANKO-CR40

The TANKO-CR has been developed for maximum chemical resistance and highest hygienic requirements. It provides impressive corrosion resistance and strong cleaning. The TANKO-CR series of spate cleaners rotate in a slow and defined manner on a maintenancefree hydrodynamic plain bearing. This constantly flushed bearing allows operation in the widest variety of installation angles, resulting in a sturdy device with a long service life. The constant speed under different operating conditions and focused fan jets ensure high cleaning effectiveness in conjunction with fast wetting.
The TANKO-CR is also very well suited for SIP sterilization of the vessel with steam. The material used is a modifi ed 2nd generation PTFE that provides a smoother, more hygienic surface than conventional PTFE with improved mechanical properties at the same level of chemical resistance and freedom from adhesion.


Srdecne vítejte, Jan Dolezil!

Since November 1, 2016, Armaturenwerk Hötensleben has also been supported by a sales representative in the Czech Republic. We have gained a competent colleague in Jan Dolezil, who is from Ricany near Prague. Initially responsible for the Czech area, Slovakia will also be one of his sales areas in the future.

At the beginning of his activities, Jan Dolezil was trained in AWH GmbH's comprehensive product portfolio. The detailed product training sessions in the areas of valve, cleaning and product recovery technology was both practical and theoretical. Getting to know the colleagues at Armaturenwerk better during this time was a desirable and pleasing side effect.

The sales representatives from Germany, France, Italy and Austria getting together at the sales meeting at the end of November 2016 also contributed to this. We have already been able to expand our customer base and therefore draw a very positive conclusion after our first few months of cooperation with Mr. Dolezil. We look forward to our continued cooperation and would like to take the opportunity to once again warmly welcome Jan Dolezil in the Armaturenwerk Hötensleben team!



Hygienic AWH Sampling Valve - EHEDG-Certified now

    We make hygiene affordable. A claim that is now backed up by the enhanced AWH sampling valve. When it comes to determining taste, appearance, and microbiological and chemical values, taking accurate samples is paramount. Our EHEDG-certified sampling valve was specially designed for this purpose. An EHEDG inspection certificate further underlines how easy it is to clean, meaning your products will not be contaminated when used properly. The AWH sampling valve comes in three different versions with a variety of port types for a wide range of applications, whether in the weld-in, weld-on or screw-in version.


    The new powerful and efficient internally geared media driven jet cleaner from AWH

      • Controlled, consistent rotation combined with high impact jets make the TANKO-MX125 the ideal choice for small to medium diameter vessels with moderate to heavy soiling
      • Hygienically designed and ball bearing free the TANKO-MX125 is suitable for a wide range of applications across a variety of process industries
      • The multi-axis 4 jet design generates a repeatable, verifiable and highly efficient 360° cleaning pattern


      Leakage Butterfly Valve with pneum. Auxiliary Valves and Actuator VMove 1

      AWH butterfly valve technology has produced another innovation: the leakage butterfly valve with pneumatic auxiliary valves. It is designed for reliable separation of media and comes with “auxiliary valves” – one leakage and one flushing valve – fitted as standard. The auxiliary valves can be activated synchronously or in isolation. Thanks to their design, both valves are easy to clean and completely isolated when closed.

      Since the auxiliary vale's sealing piston is positioned almost flush in the through-flow pipe, contamination is not possible at this point. The butterfly valve itself follows our tried and tested, hygienic design principle. The drive and auxiliary valves can be fitted with optional initiators to monitor the individual valve positions. The "double-flap principle" offers maximum safety when handling different media in the same pipe system.

      Valves for Transport of dangerous Substances acc. to DIN EN 14432

      The proven AWH butterfly valve is also available as a type-tested valve in accordance with DIN EN 14432. This certification means that the valve is extremely well suited for use in tankers and containers that are used to transport dangerous substances and liquid chemical products by road, rail or ­water. Depending on the application requirements, AWH valves can be supplied with either hand actuation or
      a pneumatic actuator.

      The new Member of AWH Cleaning Technology - TANKO-CP2

      The TANKO-CP2 is the newest member of the AWH TANKO-family. In terms of cleaning performance, the TANKO-CP2 comes between the spray balls of the TANKO-S series and the jet cleaners of the TANKO-JM series and offers a cost-effective way of effectively cleaning containers with a diameter of up to 4 m. With it slow and even rotation and strong impact, the TANKO-CP2 is suitable for cleaning containers which are used to hold contents that have a tendency to adhere strongly. The TANKO-CP2 is a system with plain bearings and a simple design with as few moving parts as possible. With its low servicing requirements, the TANKO-CP2 provides a compact and reliable solution for cleaning tasks with different cleaning media and a large temperature range.

      An era comes to an end – retirement after 42 years of service to the company

      The world's leading trade fair for beverage and liquid food technology this year, the Drinktec in Munich, was a unique event for the employees of Armaturenwerk Hötensleben GmbH and for our esteemed colleague Werner Woschke. At the end of this year, Werner Woschke will enter his well-earned retirement after 42 years of service now.

      In 1971, Werner Woschke began his career as a fitter in the AWH in butterfly valve production. In the years after that, he earned his qualification as a master craftsman and completed a degree in engineering management via distance learning. In 1980 he became line manager of production control and soon thereafter line manager of production. As manager of production process execution, in 1991 he accompanied AWH when it was acquired by the Neumo Ehrenberg Group. Since 2006 he has worked for Armaturenwerk Hötensleben GmbH as a sales representative.

      With a small stand party in his honour on 19 September 2013, we reviewed the last few years and celebrated our respected colleague Werner Woschke's last trade fair. The managing director of Armaturenwerk Hötensleben GmbH, Mr Thomas Erhorn, and the managing director of Neumo-Ehrenberg-Group, Mr. Wolf Ehrenberg, thanked him in an emotional and touching speech for his dedication and outstanding collaboration. With a cool drink and a traditional Bavarian buffet, customers, AWH employees, colleagues from Neumo GmbH & Co. KG and Gebr. Rieger GmbH & Co. KG, celebrated well into the evening. This evening will be unforgettable for all attendees.

      A company party and the dedication of a new production hall

      After a construction period of only four months, the new production hall was formally dedicated on 7 September 2013 with a company party on the grounds of Armaturenwerk Hötensleben GmbH, in the industrial area "Auf dem Rathwege". On that day, around 180 employees along with their families celebrated the expansion of the Hötensleben site.

      The party opened with a tour through the now four production halls and warehouses guided by the managing director, Mr Thomas Erhorn. Many visitors took the opportunity to take a look behind the scenes of one of the leading manufacturers of stainless steel components for the food and drinks industry in Germany. There was plenty of entertainment for the children as well: table football, a place to blow bubbles, shooting goals and much more was available?for fun and diversion. The day ended for with a spectacular fireworks show, which amazed young and old alike. The newly built hall has over 1440 m² of production space and 480 m² of offices and social rooms furnished in modern style.

      The investment costs amounted to 1.7 million euros.This investment is expected to maintain and expand the enterprise's international competitiveness. Thanks to these newly created capacities, the cleaning equipment department will move into the new premises with its product management, its design and a high-tech test facility for spray heads. The test facility for cleaning equipment was in our shipping warehouse up to now; the now vacant space there can be used for additional storage space. The workshop hall continues to provide space for the pipe grinding facility, which moved back in mid-September. The pipe grinding facility's move provides the pipe store with additional space, which it uses as a storage area for ground pipes and a new packing station for long-part shipments. The third area to be housed in the new complex is T-piece production. Here, about an additional 1 million euros were invested in new machinery.

      This is another big step towards location maintenance and setting the stage for a successful future.

      Flood disaster 2013 – AWH donates € 8,000 to the "Märchenland" day nursery

      Armaturenwerk Hötensleben GmbH and its staff have donated €8,000 to the "Märchenland" day nursery in Groß Rosenburg. During the flood disaster, most people in Germany followed the events in the media with dismay. The magnitude of the disaster for the people affected is inconceivable. That's why Thomas Erhorn, managing director of Armaturenwerk Hötensleben GmbH, appealed for a donation campaign on 11 June 2013. AWH matched every euro donated by staff with another euro.

      After three weeks the campaign finished with the proud sum of €8,000. "We found a day nursery in Groß Rosenburg, run by the non-profit organization "Lebenshilfe Bördeland e.V.", which was completely under water. There was damage amounting to approximately €200,000 at the "Märchenland" nursery, which had only just been newly renovated in 2008," said Marion Biermann, Head of Accounting at AWH. The nursery was quickly moved to an old, closed-down nursery in the neighbouring town so that the children could continue being looked after during this difficult time. According to the provider's estimations, the renovation work will continue until the end of the year. On 8 July 2013, a symbolic cheque was presented to the head of the nursery, Ms Köhler, by Marion Biermann (Accounting, AWH) and Yvonne Bischoff (Distribution, AWH).  The money was transferred to the provider's donations account with the transfer subject "Groß Rosenburg nursery", to ensure that it reached the right place.

      Ms Köhler was teary-eyed when she saw the sum on the cheque. She sincerely thanked the AWH staff and promised to keep them informed about the progress of the rebuilding efforts. AWH and its staff wish the nursery team lots of strength during the rebuilding efforts and are happy to have made a small contribution to these.
