INDUSTRIAL VALVES REPAIR

 

We repair and revitalize industrial valves on-site or in our workshop:

  • globe valves up to DN 300 mm
  • control valves up to DN 300 mm
  • safety valves up to DN 600 mm
  • gate valves up to DN 2000 mm
  • butterfly valves up to DN 2300 mm
  • taps up to DN 800 mm

ADVANTAGES

  • servicing cost is 10-35% price of the new valve.
  • industrial valves servicing takes up to five days, while for the new valve delivery time may be several months.
  • avoiding unplanned shutdowns, increasing the quality, safety and equipment life

REPAIRING PROCEDURE

  • dismantling of industrial valves
  • sandblasting and cleaning
  • inspection of damage
  • machining of sealing surfaces by grinding, lapping and in case of substantial damage turning
  • replacement of damaged parts and sealing material
  • assembling of industrial valves
  • functional testing
  • leakage testing
  • protection from corrosion
  • drafting a servicing report
