Line Orifices

Line orifices provide a 3-A sanitary and fully drainable means of adjusting process flow rate, balancing backflow, equalizing pressure, and recovering more of your valuable product.

When product reaches the orifice plate, it is forced through the hole and converges creating a change in pressure and velocity. The orifice causes an increased velocity, which means decreased pressure.

Applications:
  • Check excess flow from system header
  • Decrease pressure to a piece of equipment that can't handle the full system pressure
  • Provide required backflow to prevent pump cavitation, starvation, or motor overload and kick out
Features:
  • All bore sizes made to order
  • 20 Ra ID (SF1) standard
  • 15Ra ID EP (SF4) available
  • Machined from one piece
  • Heat traceability
  • Material certification supplied
