ARMATURY Group has been awarded the contract for reconstruction of two blocks in Chvaletice Power Plant. ARMATURY Group has supplied 12 pieces of special fully welded steel knife gate valves.
The special hand-operated knife gate valves S33.4 of large dimension will be installed in new coal powder pipeline at Chvaletice Power Plant.
