Casing Double Flange Valve
HARTMANN VALVES gear of the Casing Double Flange series are manufactured exclusively from forged steels, and are available in all sizes and implementations common to the industry, as well as also to customer specifications. The lower pipe seals are now equipped as a standard feature with testable and proven double sealing systems. Metallic sealing systems, as well as also the arrangement and implementation of the side outlets according to customer requests are a matter of course for us.
