What is a regulator?
A regulator or also commonly known as pressure regulator is a control valve that decreases the input pressure of a fluid to a preferred value at its output. Regulators are usually used for gases and liquids and it can be an integral device with an output pressure setting. They are available in many configurations and are usually contains integral loading, actuating, sensing and control components. Read more on deeper on regulator here.
How does a regulator work?
As the pressure increases, it drives the diaphragm closing the inlet valve and averting the instrument air from entering regulator. As the air is drawn out through the outlet side, the pressure inside the regulator falls.
How to select the right pressure regulator?
1. Ensure it has a normal line pressure.
2. It should have minimum and maximum regulated pressure. Regulators can have a broad adjustment range and may require a specific spring or accessory to match the requirements.
3. Determine the maximum flow required at regulated pressure.
4. Check the pipe size that’s needed.
5. Check if there’s any accessories or options include gauges and panel mounting.
6. Ensure the right pipe size and its consistency, as well as the degree of pressure precision required.
