Böhmer Fully welded ball valves

All-round dependability

To withstand even the highest loads, Böhmer ball valves are therefore welded through the entire cross-section.

Thus, weakening of the construction, for example by stress corrosion cracking on the weld seams, is actively counteracted.

Böhmer is one of the few manufacturers that actually welds the weld seams of its fittings over the entire cross-section using a complex process.

Various testing procedures are used to confirm the tightness of the entire ball valve. Furthermore, weld seams undergo visual, magnet particle, ultrasonic and – if requested – radiographic testing.

And we do not rely only on ourselves. We contract external institutions to confirm the perfection of our products. The weld seams thus comply with the legal regulations for the construction of pipelines, reservoirs, tanks and containers.

Features of our fully welded Ball valves


We spend a great deal of time and money and make considerable effort to ensure that the weld seams can withstand extreme conditions. That is the reason why our full-welded ball valves operate reliably even under high pressure. The precision design and manufacturing of all components enables safe operation at all times


In addition to their robust design in respect to internal and external influences, our ball valves provide considerable savings potential for transporting, installing and servicing ball valves. Our ball valves are thus an economical solution, especially in the long term.

Fire Safe

ire-Safe ball valves have been specially designed for use in critical areas. Thanks to the special design and the particularly resistant materials, Böhmer Fire-Safe ball valves retain their full functional reliability even at temperatures above +650 ° C.


All welding seams are carried out by our trained welding specialists and checked by our welding engineers.

Our company is process-tested according to DIN EN ISO 3834-3729 and AD-HP 2/1 (TÜV)
