| Carl Reuther, together with Carl Bopp, founds a special factory for manufacturing pumps and heavy-duty valves. | |
|
| 1900 | ||
| Bopp & Reuther supplies 60% of the world's water gate valves. A water supply plant large enough to supply an entire city can be produced at the factory in the Waldhof district of Mannheim. | |
|
| 1903 | ||
Setting up of the division steam valves: Safety valves with direct weight- and spring loading; shut-off valves, steam traps, throttle valves, exhaust valves and steam reducing valves. |
|
|
| 1932 | ||
| Entering measurement technology opened the way to the development of the oval wheel meter. With this high-precision liquid volume meter, Bopp & Reuther engineers succeed in inventing a basic measuring device, which is still highly regarded and widely used today in many different versions and applications. |
|
|
| 1951 | ||
| Production of pressure reducing valves with auxiliary control units starts in 1951. This was the beginning of the development of a range of safety valves for conventional and nuclear power plants, as well as for use in plants in the chemical and petrochemical industries. | |
|
| 1990 | ||
| With the arrival of a new shareholder, IWKA AG, the company is reorganized into divisions operating as independent companies. In addition, two new companies are brought into the Group: IWK Regler und Kompensatoren GmbH of Stutensee, and RMG Regel+Messtechnik GmbH of Kassel. These additions to the Group result in a substantial expansion of the fields of activity, incorporating broad areas of modern valve, measurement and control technology. |

|
| 1997 | ||
| Introduction of the API-spring-loaded safety valve. With it B&R SR not only perfects the range of safety valves but also expands the scope of delivery to broad areas of ASME-Specification which becomes more and more important all over the world. |
|
|
| 2000 | ||
| Takeover of the servicing activities of Zikesch (gate valves and valves for utilization in power plants). | |
|
| 2001 | ||
| Takeover of the companies „Pier Armaturen GmbH“ and „AGP“: B&R SR is able to further expand its range of delivery by gate valves and nonreturn valves. The foil safety valve opens completely new market segments. |
|
|
| 2003 | ||
| Introduction of the EN – safety valves. With the standardization of the European Standards a new series of valves is born. |
|
|
| 2004 | ||
| Manufacturer Approval in accordance with ASME Sec. III. Thus, B&R SR expands the market for nuclear valves to installations worldwide. | |
