Gas Pressure Regulator – How to select a gas regulator

October 2, 2007

The Deep Dark Secrets of Selecting Gas Pressure Regulators…Simplified 

Selecting a gas pressure regulator isn’t nearly as complicated as it seems.  Although there are many considerations that must be weighed over a broad range of applications, the truth is that the majority of regulator selections are pretty simple if broken down into four basic questions: type of gas, inlet pressure, outlet pressure, and flow.  Once these four questions are answered, the only thing’s left are purchasing a quality product from a trusted source and having it properly installed by qualified individuals. 

As mentioned, we need to answer four basic questions to ensure trouble free results: 

What kind of gas will be used?  We could go into great depth concerning chemical properties of various fuel gases, but who wants to go to school so they can purchase a gas regulator?  What we really need to know is what kind of gas we’re using.  95% of the time it comes down to two choices, natural gas or propane. The other 5% of applications can be taken care of, too, as long as the fuel is positively identified.   

What’s the inlet pressure?  This can be a little tricky if you don’t have a pressure gauge already installed where you’re working (we have what you need in stock).  It’s almost never written down and nobody seems to know.  If you have to, call the gas company and ask them the supply pressure to your building which will be needed in selecting your gas regulator. 

What’s the desired outlet pressure?  Outlet pressure from a gas regulator is controlled by a spring in a “tower” on top of the regulator.  There is cap on the tower that, when removed, allows access to the adjustment of a spring.  The chances of picking a regulator with the exact outlet pressure you need is about the same as winning the lottery, so gas pressure regulator manufacturers utilize a series of springs that fit the same regulator.  A properly selected spring range adjusted to the desired compression will fit the outlet pressure you’re looking for. 

What’s the flow?  An easier question would be “What’s on the nameplate?”  There should be information on a tag or plate at or near the burner listing the BTU rating or capacity.  If you have the original documentation, that may help, too.  If it’s old and you can’t find any information, we’ll try to help you figure this part out as best we can.     

What’s the desired pipe size?  We left this part out when we started this discussion.  Gas Pressure Regulators aren’t always as friendly to your pipe fitter as your salesperson because gas regulators sometimes aren’t the same pipe size as the rest of the gas piping.  A selection will be made as close as possible to the correct pipe size.  The difference can be made up will bell reducer fittings. 

When you get the answers to the four questions (five if you know what pipe size you would prefer) making a selection should be a snap.  In fact, at that point you really don’t even need to make a selection.  We’ll assist with the selection and probably ship it out the same day. Now that’s service!!
