MAXIMUM SAFETY AND RELIABILITY
This what Böhmer requires of its products. For 60 years in Sprockhövel and since 1999 in the second plant in Hattingen, Böhmer has been manufacturing ball valves that set standards in quality and operational safety. At the beginning, there was the idea of developing a safety shutdown valve for mining. The success of this product soon prompted our company to expand its portfolio to include oil, gas and district heating.
Böhmer now manufactures ball valves for nearly every application, in sizes from DN 3 to DN 1400 (1/8″ to 56″), suitable for pressures of up to 500 bar (Class 2500).
No fear of difficult fluids
Whether gasses, liquids or solids, sturdy designs and very durable materials are used to meet extreme demands. The absolute suitability of Böhmer ball valves has been proven by all established test and certification procedures. It is no coincidence that Böhmer products are most frequently used as references when high performance of safety shutdown valves is required.
To maintain this status, we continuously invest in modernization and innovation. In our production facilities we have one of the most modern machinery in Germany. New materials, constructions and procedures are developed in house and extensively tested. Nevertheless, we are convinced that it is ultimately the experience and motivation of our employees that make the high quality of the product possible. True to our motto: Our experience – your safety.

Künneth & Knöchel was founded in Magdeburg in 1887 and has been manufacturing vulcanizing units for worldwide use.
Every unit is manufactured for a specifi c application. We build units for conveyor belts with fabric or steel cord plies up to a belt width of 3,200 mm. The heating platens and pressure bars we use are made of high-quality special aluminium to give many years of reliable service with a high tensile and bending strength. They are selectively available in the forms rectangular shape or rhombic 16.42°, 22° or 30°.
The electrical heating of the heating platens is realised by flat tube heating elements as well as heating foils. The flat tube heating elements are embedded in stainless steel tubing for protection against rust and moisture. Direct contact of the tubes with the heating platens ensures rapid heating. The heating foils are made of silicone with a temperature resistance up to 220°C. The heat flow is evenly distributed everywhere because the heating foil covers the whole surface.
For rapid cooling, our vulcanizing heating platens are available with optional compressed-air or water cooling system. With the water cooling system the heating platens can be cooled down till 80 °C within 10–15 minutes. The electric controller of our vulcanizing units can be operated alternatively by hand or automatically.
We stock a wide range of spare parts to provide a 24-hour service within Germany. All vulcanizing units are thoroughly tested by qualifi ed specialists prior to delivery, including safety and functional tests according to VDE0100 to ensure the highest standard of quality for our products. Only a perfectly functioning vulcanizing unit ensures a perfectly spliced conveyor belt.
