Voith Turbo Acquires Valvex Ventiltechnik

Crailsheim, Germany -- As of April 1st Voith Turbo GmbH & Co. KG, Heidenheim, Germany, is taking over Valvex Ventiltechnik GmbH, Bergisch Gladbach, Germany.

Valvex Ventiltechnik, founded in 1971, specializes in developing and producing explosion-proof solenoid valves and valve groups that are used primarily in the mining and in the refrigeration industry. During the course of the takeover, the company will be fully integrated into the Product Group Electric Control and Drive Technology within the Voith Turbo market area industry at the location Crailsheim.

The product program of Valvex is an ideal supplement to the Voith Turbo portfolio. Valvex products are used in all cases where high availability is the main criterion in environments with explosion hazards. Since 1975, Valvex solenoid valves have been widely used in underground mining applications.

The valves are utilized for dust suppression (crusher, plough track and transfer spraying), for mine ventilation and for the control of armored chain and belt conveyors (for example in Voith Turbo couplings) and band brakes. There are also numerous special applications. Above ground, the explosion-proof solenoid valves are used in refrigeration plants.

Voith Turbo is a worldwide leader in energy technology and stands for continuity in its markets. The implementation into Voith Turbo ensures the long-term availability and further development of the Valvex products.

Meco To Exhibit New Seal Designs at Powder Show

Georgetown, ME -- Booth 2414 at the International Powder and Bulk Solids Expo in Chicago will be buzzing with the latest innovation in sealing technology: the outside face seal (OFS). This single-face design was originally conceived for high-temperature and high-speed applications, where double-face seals can overheat and fail. The OFS is ideal for the containment of vapors in vertical-shaft vessels and operates without a purge or flush system.

MECO earned its most recent patent for this design, which maintains constant seal-face pressure as components wear. The OFS is particularly suited to top-entry agitators, where long, cantilevered shafts can exhibit high runout and angular misalignment. The OFS will permit significant axial motion, making it ideal for applications where there is shaft float and thermal expansion.

The OFS is available unsplit or fully split, and in a wide variety of materials combinations for maximum compatibility with acids, bases and aromatic hydrocarbons. The OFS can be built with no elastomers, permitting its use with aggressive chemistries. OFS seals excel in vacuum environments, often cutting process times in half, due to increased vacuum containment.

All MECO seals are custom-engineered to suit individual applications, providing an excellent alternative to packing glands, which is simple to install in rotating bulk process machinery. Used in industries as diverse as chocolate, polyolefins and gypsum processing, these fully split seals effectively contain solids, liquids, vapors and gases. MECO builds a minimum of 6mm diametric shaft run-out into all of its designs. Those models which are air-purged use very low flow rates, approaching zero cfm.

MECO custom shaft seals are designed and manufactured by Maine craftsmen at Woodex Bearing Company.

Mr. Luken wants help with scale formation:

My name is Arne Luken and I am studying process engineering in Hamburg Germany. In line with my studies I am working on a research about the phenomena of scale formation which occurs while transporting fluorated or secondary alumina with pneumatic dense phase conveying systems.

Secondary Alumina originates in the dry scrubbing process, where fresh Alumina is used to adsorb the emissions from the off-gases of the electrolytic cells. For now it seems like the principle occurrence of scale formation is independent from the geographical location and the dense phase conveying system itself, whereat it does differ in speed of growth.

Furthermore it seems that the Alumina itself is not the initiator of the problem, rather the fine dust or particle emissions seem to provoke the build up. Another interesting fact is that the incrustations increase at places of high turbulences (for example at bows and primary at the end of the conveying pipe due to higher velocities).

Since this is a very particular problem I found it very hard to find any kind of literature or previous researches about this problem. Therefore I would be very pleased about any kind of information or knowledge like: Hints, Literature, Links, Contacts, Ideas, or Researches

Thanks in advance for any leads.  (to post reply, click here)
