Why Do You Need a High Pressure Regulator for Your Gas?

Pressure gas regulators are commonly found in the home and industrial applications, like heating furnaces, gas grills, and kitchen equipment. Gas regulators are also used to pass high-pressure supply tanks/lines to be reduced to usable and safe pressure for different applications. The majority of gas regulators are designed with a sensing element, control element, or a loading mechanism.

These are the three essential components that work together with one another to make pressure reduction possible. The usual loading mechanism is a spring, which is responsible for identifying the delivery pressure of the high-pressure gas regulator.

How Does It Work?

When you turn the hand knob on a gas regulator, the spring will be compressed. In return, the response expels the sensing element which causes it to set the delivery pressure.

This sensing element is usually a diaphragm made either from metal or elastomers. After the displacement, the diaphragm will then push the control element valve, urging the valve to increase its size, which then supplies the flow and pressure needed.

Common Types Of High Pressure Gas Regulators

The most common types of gas regulators in Malaysia are:

A) Line Gas Pressure Regulator

This type of gas regulator is to serve low-pressure pipelines that can be used together with high-pressure cylinder regulators. They can maintain a pressure level of around 250 to 400 pounds per square inch (PSI).

B) General Purpose Gas Pressure Regulator

This type of gas regulators are affordable and have a long life. They are usually used for applications in the non-corrosive plants, maintenance shops, and pilot lights.

C) Two-Stage and Single Stage

High-pressure gas regulators work with the use of either a two-stage or a single-stage process. Keep in mind that you need to choose the regulator that will work with the kind of application where the function is needed.

D) High Purity Gas Pressure Regulator

This type of regulator is easy to clean up, providing diffusion and resistance. The main benefit of these regulators is that they can eliminate or minimize inboard diffusion with the work of high purity seals and seats and metal diaphragms.

E) Special Service Gas Pressure Regulator

This type of high gas pressure regulator is intended for a specialized application like ultra-high pressure, corrosion service, and acetylene.

How To Select A High Pressure Gas Regulator?

Before buying a high gas pressure regulator, it’s best to consult your gas regulator supplier, such as COMeT Integrated. Our friendly personnel have the knowledge and expertise to help you select the gas regulator for your needs.

Step #1 What Is The Pressure Needed?

You need to determine the specific pressure you need for a specific instrument to select a gas regulator with the correct outlet requirements or a variable range which includes the value needed.

It is also important to note the inlet pressure entering the regulator. This is commonly known as “Inlet and Outlet Pressure”. Always choose the range that matches your requirements.


Step #2 Gas Type and Concentration

The gas mixture or gas type will decide the material needed by the regulator. It will also help to select other materials such as tubing.

  • Non-corrosive gas mixtures, such as: LPG, Natural Gas, CO, CO2, O2
  • Highly corrosive gases, such as: Chlorine, Ammonia, Nitrogen Dioxide, Hydrogen Cyanide

Step #3 What is the Inlet-Outlet Connection?

Gas installers must find out the regulator’s Inlet-Outlet connection.

This is to help ease the installation process of the gas regulator to fit onto the gas pipe.

If required, reducers are needed to match the pipe size to the regulator’s connection size.


Step #4 Do you need a Single or Two-Stage Regulator?

If you need a low pressure supply, you may use a low pressure regulator. However if the distance of the pipe work is short, two-stage regulator (dual stage) may be used.

This is an integrated first and second stage regulator into one regulator. It is much more convenient to install and has the functionality of both high pressure and low pressure. However, this is highly dependent on your installation’s set-up, industry, and local regulatory compliance.

Finally, before you operate a high-pressure gas regulator, remember that proper training or supervision by your Malaysia gas regulator supplier is required. For more information, contact us anytime.
