Designing a flow control systemFundamental steps in designing a valve:1. Establish the required flow performance• Single phase (liquid or gas) or 2-phase• Fluid Properties• Capacity & flow rate• Accuracy & repeatability2. Identify the required pressure conditions• Pressure Drop & inlet pressure3. Decide the method of control & actuation• On-off or regulating/modulating• Response time• Mechanical or electrical actuation4. Optimise the product & system performance5. Design a stylish, robust & compact enclosureFlowPressure14
