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.
