Hydrogen ball valve: FDA conformity and metal-to-metal sealing system

13. July 2018

Hartmann special valve fulfils high level requirements for the food industry

The new development from Hartmann Valves simultaneously combines several characteristics aimed at maximum leak-tightness, safety and durability: designed for hydrogen and fitted with a metal-to-metal sealing between the ball and seat ring, the ball valve fulfils a leak rate of A or 0 and also complies with the high level purity requirements of the Food & Drug Administration. 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.
The ball valve was developed for the specific application of a global Life Science concern. Within the course of manufacturing a special solvent medium, soft sealing shut-offs could no longer guarantee hydrogen leak-tightness on contact with solids.
As with all Hartmann valves, the design can be adapted to individual customer requirements.
