What is a Gas Regulator?
A gas regulator is an internal valve system used externally to control the pressure of a gas cylinder. It helps reduce the cylinder native pressure down to the desired outlet pressure. It's very important to use one to make sure the amount of output pressure is correct for the application it's intended for.
There are different types of regulators, each meant for specific jobs based on long-term, heavy duty cycles, and short-term, light duty cycle applications.
Single-Stage Regulators
These kind of regulators are used for short term applications. They use only one step to control the amount of pressure. This is great choice for small gas-related jobs. However, if you need to work with gas on a long term basis or long duty cycle, you'll need a dual-stage regulator instead.
Best For: Short-term applications
Ideal for small jobs, occasional use, and cost-effective solutions.
Dual-Stage Regulators
If you require a long work duty regulator, it's recommended you go with a dual-stage regulator. As the name suggests, there are two stages to help regulate the gas pressure. It is strongly recommended to use dual-stage regulators on jobs that require large volumes of gas over a long period of time.
Dual stage regulators can be used for short-term applications as you would with a single stage regulator. One drawback for dual-stage regulators is their cost. It would be more cost effective to go with the single-stage rather than dual-stage if you just need one for small jobs.
Best For: Long-term, heavy-duty applications
Essential for large volumes of gas over extended periods. More expensive but provides better pressure control.
Liquid vs Gas Regulators
Important: Use the Correct Regulator Type
This is due to the corrosive nature of liquid gasses. An example would be a CO₂ tank. Liquid CO₂ is normally at around -70 degrees Fahrenheit in its liquid state. This extreme cold would seize the regulators internal components and destroy any seals or gauges within. This can causes very dangerous conditions to the operator and his surroundings.
How To Use a Regulator
Inlet Pressure Gauge
Shows the amount of pressure currently in your gas cylinder. This helps you monitor how much gas remains in the tank.
Outlet Pressure Gauge
Shows the amount of pressure in the gas exiting the cylinder. This is the gauge you'll adjust to control your application's pressure.
Step-by-Step Instructions
- Connect the gas regulator to the gas tank's valve inlet port.
- There is an adjustment screw that controls a spring on the regulator. That spring helps open and close the valve in small increments.
- Once the regulator has been carefully tightened, open the gas tank's main valve.
- Fasten the regulator screw clockwise or counterclockwise. This is what makes the regulator control the amount of pressure to be outputted. You want to fasten the screw until it outputs the desired amount of outlet pressure.
- Pay close attention to the outlet pressure gauge readings. You never want excessive pressure to come out, especially in enclosed areas, as that could lead to serious consequences depending on the gas used.
Critical Safety Reminder
Sickness and even death can occur without proper training and supervision.
ALWAYS, when you have completed using your regulator, close the main valve and purge any remaining pressure from the regulator. This will prolong the life of the regulator as well as prevent any leaks or gas waste.
