For Challenging Applications

Ball valves

07.05.2015 Hartmann Valves' ball valves, designed for challenging conditions, are constantly pushing the technological envelope. Gas-tight and with entirely metallic sealing between ball and seal ring, the valves are resistant to aggressive media, high pressures and extreme temperatures.

These German-made valves are designed exactly to the respective customer requirements for process optimization. With the development of valves (DN125 PN160) for pure oxygen at 350 °C and water vapour at 450 °C, an oxygen addition could be realized which greatly enhances the efficiency of a customer‘s process. Other valves (12″ PN50) have ensured high plant availability trouble-free for four years – by absolving some 400,000 cycles in degreasing media at about 200 °C. Furthermore, ball valves for hydrogen applications permit the feeding of hydrogen from renewable energy sources into the gas transportation system. For coal pressure gasification facilities 20″ valves for use at over 400 °C have already been delivered. The valve tightness has been verified by an abrasion test at 425 °C with helium as test medium. For abrasive media such as titanium dioxide (TiO2) the manufacturer developed an 8″ valve for portioning the oxide. Using this ball valve, servicing intervals of a few weeks could be lengthened to 15 months. In this time the valve completed about one million cycles.
