Process regulators

Process regulators, also known as pressure regulators or control regulators, are used to control pressure and in some cases temperature in various processes. What makes a regulator a process regulator? It depends on the design criteria of the regulator and the technology that it is being used in. In short, a process regulator is designed specifically for a process. In many cases if a regulator has many different body and trim configurations that can be used in a variety of process applications, depending on which options are selected.

Different types of process regulators

There are two different types of process regulators; pressure reducing regulators and back pressure regulators. The purpose of the pressure reducing regulator is to reduce a higher pressure to a lower pressure, while pressure reducing regulators act to reduce pressure by controlling the pressure on the outlet or downstream side. Our range includes both pressure reducing regulators and back pressure regulators.

Some common industries and applications 

Regulators are commonly used in industry; for example breweries use many assorted styles of regulators to control steam, water and carbon dioxide. Food Processing regulators employ special FDA approved materials that will not contaminate the food or beverage being processed. Pharmaceutical regulators have even a higher demand for compatibility, some of which are USP Class VI, which is used for fluids that are directly injectable into the body. Steam flood regulators are used in steam injection systems which are employed when oil is very viscous and must be heated before it can be pumped out of the ground.

Process regulators for Natural Gas

There are hundreds of diverse types of natural gas regulators that are used to not only reduce pressure or relieve pressure but can also slam shut in the event of a line break. They may also be used as monitoring regulators that will take control of the process if another fails. Some regulators can control very high pressures (200 barg) and others are used to control pressure as low as 10 cm of water column.

Cryogenic process regulators

Cryogenic process regulators are used to control liquid nitrogen and oxygen with temperature as low as -195°C. Oxygen and nitrogen are usually stored as liquids and special regulators are employed to provide the required flow of oxygen or nitrogen gas to the user.

Frequently asked questions about regulators 

What does a regulator do?

Process regulators help reduce high-pressure fluid streams to lower levels before entering downstream equipment or processes, protecting equipment from damage.
A regulator works to control and maintain a specific pressure level within a system. It achieves this by adjusting the flow rate of a fluid (liquid or gas) passing through it to ensure that the pressure at the outlet remains within a desired range. 

How does a regulator work?

Process regulators continuously monitor pressure and compare it to a setpoint or desired pressure level. If pressure deviates from the setpoint, the regulator's control mechanism adjusts the valve position to increase or decrease flow rate.

Which is the most common type of regulator? 

Pressure reducing regulators make up approximately 85% of all regulator applications. Other types of regulators, such as flow control regulators, back pressure regulators, and vacuum regulators, are also widely used in their respective applications. The choice of regulator depends on factors such as the intended use, required pressure control, fluid properties, system design, and regulatory requirements specific to the industry or application.
