Throttling Valves

  • A throttling valve is a steady-flow engineering device used to produce a significant pressure drop usually along with a large drop in temperature
  • In a throttling valve, enthalpy remains constant
  • No work device -mechanical or other forms
  • Heat transfer almost always negligible
  •   –small area; less time available
  • PE and KE changes usually negligible
