What is Gas Regulator? And How Does It Work?

What is a gas regulator? Gas regulator is used in any social aspects, from the basic household use to a more massive industrial use.

This piece of equipment ensures that the gas that flows through the lines into the equipment, the regulator also makes sure that the gas is flowing with the right amount of pressure.

The safety role of gas regulator is also important, imagine that you have too much gas pressure, this condition can lead to a catastrophic explosion, harming you and your property,

So, what is a gas regulator? How does the gas regulator work? Let’s break it down here!

What is Gas Regulator

Gas regulators can be a little confusing, with a wide variety that also serves a different purpose based on the application.

We’re here to guide you, but knowing a bit about regulators goes a long way. 

Understanding how they work, the difference between reducing and regulating pressure, and the pros and cons of single-stage vs. double-stage models will help you pick the perfect one for your needs.

Gas regulator was first designed in 1835, but the modern gas regulator that we know today was invented in 1860 by a French mining engineer Benoit Rouquayrol.

There are various types of gas regulator, but basically, it serves one same purpose, which is to control the pressure of natural or propane gas flow.

To put it simply, there are three main components that work together to ensure the flow of the gas through the valve.

The loading mechanism that sets the desired pressure; the sensing element which is a diaphragm that senses when the pressure is reached; and the control element that keeps the flow steady.

How Does a Gas Regulator Work?

To put it simply, let’s Imagine a regulator is like a gas pedal for your appliance! Gas flows into the regulator and pushes on a diaphragm, like a tiny piston. 

This movement controls how much fuel goes through. The knob you turn is like adjusting the gas pedal. 

Turning it clockwise lets in more gas, and counter-clockwise reduces the flow for a gentler flame.

Another component affecting how the gas regulator works is the surrounding air, the different altitude will affect how this thing works.

The regulator senses pressure on both sides of the valve, and outside air pressure can influence how it reads downstream pressure.

Types of Gas Regulator.

Primarily, there are two types of gas regulators:

1. Dual-Stage Regulator

This type of regulator utilizes two regulators within the same housing. To put it simply, the dual-stage regulator has two stages to regulate the pressure of the gas. 

At the first stage, the pressure is reduced to generally three times the maximum working pressure.

And after that, the second stage further fine tune the pressure to a reasonable working pressure. 

Dual-stage regulators sometimes have two safety valves, so the chance of explosion is greatly reduced.

2. Single-Stage Regulator

Single-stage regulators are almost the same as dual-stage regulators, the mechanism is also (almost) the same.

The difference is that the single-stage regulator only controlled the pressure of the gas in one single stage. Thus the delivery pressure is not as controllable as the dual-stage.

So here you are all about the gas regulator that you need to know.

To ensure your safety we recommend you to buy a regulator that has an SNI logo on it.

But what is SNI? SNI is a certification to ensure that every product, including the gas regulator, is up to Indonesia’s safety standards.

Almost every product that is sold and distributed in Indonesia must go through the SNI certification.
