Multi-stage restriction Orifice Assembly

Flow Measurement Excellence
  • Restriction orifice Assemblies are used for managing pressure drops / control flow rates by restricting flow, irrespective of downstream conditions. 
  • Multi-stage restriction orifice assemblies are ideally used for high pressure drops and/or high noise applications. MSRO’s are designed to prevent cavitation, critical flow, flashing and excessive nose or vibration from occurring.
  • Available in MOC suitable to your process needs ranging from Austenitic steels, Nickel Alloys, PVC, PTFE and Stellate coated.
Available Designs / Customizations
  • Single Bore Orifice Plate
  • Multi-Bore Orifice Plate
  • - All RO’s are designed in accordance with ISO 5167 / ASME Standards and R.W.Miller.
    - The Reduced Noise levels are in accordance with B.S. EN60534-8-4.
    Suitable for high pressure drops for both Gasses and Liquid.
    Low cost compared to control valves up to 10 times lower and easier to comparatively design and install.
    No Moving or Electronic parts involved.
