Higher The metal-to-metal sealing system shut-off the ball valve gas-tight, even in large dimensions and in low- and high-pressure ranges. The ball is rotating in its own volume, this allows reliable switching without blocking by contamination. Special safety is provided by the design with double piston effect, in which two seals are installed in the direction of pressure.
Minimized The design of Hartmann ball valves ensures a long service life. There is no need to regrease or replace stem seals. We only recommend a regular check to increase the service life of the ball valve.
Higher Due to the metallic sealing system, there is no need to use grease. This prevents contamination and increases system availability. Therefore, breakdowns due to time-consuming maintenance are eliminated.
Reduced The design of Hartmann ball valves allows a minimization of downtime and increases the productivity of the plant. The low maintenance requirements minimize the costs for planning, service and spare parts.
Environmentally The stem seal fulfils the thresholds regarding the emissions of ISO 15848. The design also makes it possible to dispense with grease or sealant, thus reducing resource consumption.
