Restriction Orifice Plates for Pressure and Flow Control
Globe United supplies restriction orifice plates and assemblies for controlled pressure reduction and flow limitation in liquid, gas and steam services. Each requirement should be reviewed using the actual process conditions because pressure ratio, phase, noise, cavitation and velocity can affect the appropriate design.
Single Stage and Multistage Selection
A single stage restriction orifice may suit duties where the required pressure reduction can be achieved within acceptable operating limits. Multihole or multistage arrangements can be considered when pressure drop, noise, vibration, cavitation or flashing requires the reduction to be distributed. Final selection must follow an engineering review of the submitted data.
Information Required for Review
- Fluid composition and phase
- Normal, minimum and maximum flow rate
- Upstream and downstream pressure
- Operating and design temperature
- Pipe size, schedule and material
- Required material and flange standard
- Allowable noise and pressure drop limits
- Inspection, testing and documentation requirements

Frequently Asked Questions
What is the difference between an orifice plate and a restriction orifice?
An orifice plate is commonly used as a primary flow measurement element. A restriction orifice is selected mainly to limit flow or reduce pressure.
When should a multistage restriction orifice be considered?
It can be considered when the total pressure reduction should be divided into stages to manage operating risks such as excessive noise, velocity, cavitation or flashing.
Send the process data to Globe United for review. See also the multistage restriction orifice.
