CHECK VALVE FOR DRINKING WATER SERVICE.


  • For the drinking water conduction, it must be considered that the body and trim materials can react chemically with the water producing oxidation or corrosion that generates toxic materials that affect the quality of the drinking water. To avoid the above, an interior and exterior coating must be used to avoid the contact of water with the manufacturing materials that may react.
  • These valves are generally painted in blue color for easy identification.
