Our high performance valves guarantee the highest level of safety and availability. Designed to individual customer requirements they resist aggressive media, extreme pressures, temperatures and high cycle operations. The metal-to-metal sealing between ball and seat ring provides an especially long service life and minimizes the requirements on maintenance. Besides the conventional ball valve designs we also produce pig valves and twin ball valves for increased safety requirements as well as multi-way ball valves. We develop special tailor made replacements for existing valves.

Our API 6A conformant wellheads are designed to the highest requirements and have been deployed for decades in oil and gas production, storage technology and deep geothermal energy. Produced from high quality materials they are equipped as standard with metallic sealing ball valves. Due to an integrated design, not only is the installed height and weight minimized but by saving on flanged connections the safety is improved above all. An experienced service team is available around the clock for assembly service, repairs and maintenance work.
