Do you require a pressure regulator or a flow regulator? All high-pressure regulators are made to accept incoming pressure of 150bar from the cylinder. This makes them a high-pressure regulator. But what do you need on the outlet of the regulator. Exactly what does your instrument/analyser/GC require? Pressure or flow?

Usually, a gas detection tool will need stream (.5l/min) in which a gasoline analyser may require stress at 1 or 2 bar. The tool, analyser or GC will determine precisely what is required.

As soon as this can be decided we can keep on.

Step Two: Exactly what is the electric outlet flow rate or pressure necessity?

Specific flow prices or pressures may be necessary for a specific instrument or analyser.

Identifying that degree will allow us to pick a regulator using the correct outlet requirements or even a adjustable range which include the value required.

Stream: Numerous regulators have specific stream prices that are fixed, while others have a variety of stream prices. A constant flow regulator can provide the required stream rate required by the tool. In situations where the analyser comes with an internal pump then an on-need flow regulator will give you the flow after a vacuum is placed around the regulator.

Pressure: All stress regulators have outlet ranges such as -1.5bar, -3.5bar or -10bar. Select the range which matches your necessity. If your analyser demands 2 bar then pick the -3.5bar range.

Step Three: Gas type and concentration: The gasoline mix or gasoline type will determine the material requirement of the regulator. Additionally it is important when picking many other materials including tubes.

Extremely corrosive gases including chlorine, ammonia, nitrogen dioxide, hydrogen cyanide require stainless steel regulators.

Hydrogen sulphide and sulphur dioxide can use nickel coated brass when the focus is below 50ppm. Higher concentrations of H2S and SO2 require stainless-steel.

Non corrosive gas mixtures including CO, CO2, O2 and many hydrocarbons would require brass. It is important never to use nickel plated brass for high levels of carbon monoxide, as CO and nickel are incompatible and can type tetracarbonylnickel.

In which high wholesomeness gasoline levels are utilized with highly corrosive fumes, purging techniques are suggested.

Stage 4: What inlet connector do you require? Flow or Pressure Regulators

The gas type or gas mix will dictate what device type is around the gas cylinder. Aussie (AS), British (BS) or North American (CGA) standards are typical depending upon where gas mixture was manufactured. The inlet connector in the regulator must match the gas tube valve. You have to figure out what type of device is on the tube, regardless of whether which is an old cylinder or perhaps a new cylinder. The content from the device and regulator is going to be depending on the gas kind.

Inlet connectors can be changed to match the gas mixture if neccessary.

Step 5: Would you need a solitary or double stage regulator (stress regulators only)

The electric outlet pressure of any specialty gas regulator comes with an inverse relationship to the gasoline volume inside the cylinder. As the gas volume decreases the electric outlet stress raises.

Would you demand a constant electric outlet pressure throughout the use of your analyser? Often evaluation may take the time to finish therefore the analyser is left unattended.

Should you require a constant pressure being sent to your analyser then the double phase regulator is required. The dual stage regulator corrects for the increase in outlet pressure and maintains the pressure on the rczlsg device. Depending on step 2, in the event you require a 2 club constant outlet pressure you will decide on a double phase regulator with all the range -3.5bar and set the benefit to 2 club.

If a rise in electric outlet pressure is not important then a single phase regulator will be suitable for your application. Inside the case of any -3.5bar range regulator the best outlet pressure could be 3.5bar.

Solitary and dual phase regulators are accessible for all types of components of pressure regulators.
