ten arGUmentS in faVoUr of BÖhmer BaLL VaLVeS for DiStrict heatinG We know that our products deliver what they promise. To give you an idea of the numerous advantages of our ball valves, we have compiled the following list of some of the special features. The full penetration of the weld seams enables our ball valves to withstand even extreme stresses, thus ensuring safe operation of the valves. The elongated weld ends fulfill more than the required standard, while machining operations ensure absolute roundness of the weld ends. The spring-supported ball seals ensure longer service life and...

The solid ball ensures top operational safety without the loss of flow. The separation of the bonnet from the flow of hot water / steam reduces the thermal stress on the insulation. The enclosed limit stop is not exposed to dirt and thus ensures exact positioning of the valve in its end positions. The BÖhmer position indicator is designed with a two-flat header and a red-colored direction notch showing the exact position of the ball even after assembly of BÖHMER accessories. The redundant seal of the stem ensures absolutely hermetic seal-off from the environment. Due to the different types...
