Maxon Valve sizing charts Datasheet

  • Hello! I've reviewed the provided datasheet, which contains valve sizing charts for various Maxon valves. The document provides information on calculating approximate pressure drops based on flow rates for the models listed. I am ready to answer your questions about the valve models and their specifications.
  • What is Q1?
    What is ΔP1?
    What does S.G. stand for?
    What is the document about?
