Q: How big valves are used in a DN159 pipe?: Nominal diameter DN150 corresponds to the outer diameter of De159To say DN159 is wrong, because DN is the nominal diameter (diameter in the middle of the tube wall)De159 refers to the outside diameter (outside the diameter of the wall)DN39 should be DN32. Nominal diameter 32, outer diameter 39.

Q: How to better maintain the valve?: How to maintain the valve?Enter the same as other mechanical products, but also the need for maintenance.
