Mockup - An Engineer's Guide to Selecting a Flow Restrictor

A flow restrictor is any device that restricts or limits the flow of a fluid—generally a liquid or a gas. Such devices may also be referred to as flow limiters. Calibrated orifices are one example of flow restrictors. They are used in systems we encounter daily. For example, they control how fast water flows from a faucet, how quickly foam sprays from a bottle of carpet cleaner, and how much fuel is flowing into the engine of a car.

Engineers tasked with managing fluid flow may refer to holes and to calibrated orifices, two very distinct entities. A hole can be any opening; a calibrated orifice is specially designed to precisely control fluid flow, and its diameter, length, and geometry are critical to its intended operation. With the proper design, an orifice can provide the desired control of fluid flow rates and pressure spikes.

In this brochure, you will learn all about how to select a Flow Restrictor capable for your needs.
