Designed for hydrogen and fitted with a metal-to-metal sealing between the ball and seat ring, Hartmann Valves’ ball valve fulfils a leak rate of A or 0 and also complies with the high level purity requirements of the FDA. With FDA conformant components such as O-rings and the hard coating of the sealing system, the valve is also suitable as a reliable shut-off for use in the foodstuffs industry.
Additional safety is provided by the double piston design in the upper seat ring which constitutes a second barrier. A leak-tightness check can be made at any time in the installed state by means of an integrated drain valve and injections are also possible by this means.
