Kugelhahn

Ball valve is drawing on oversea rigidity seal technology in design and manufacture, using a special seal structure, with reliable sealing performance, to truly realize the zero leakage. Ball valve body and seat have a good cut off self-cleaning function, as a result of the elimination of be stuck by dust particles bonded seal valves. High-performance super-wear-resistant ball valve seal block adopt vice supersonic speed flame spray finishing with the ultra-Wear-resistant tungsten carbide alloy, to make it with high hardness and wear performance of extraordinary, its hardness up to HRC75 80 and its life is 8 times than conventional metal seal ball;It's suitable for working condition system of organic silicon, polysilicon and other special projects.
