Gas Pressure Regulator

I am trying to find out the specifications on a gas pressure regulator that is at the meter outside of a house in Dallas. The regulator has Lancaster 61NMP stamped on the body, and 3/16 orfice Type R on the cap to the spring. I cannot find anything on this regulator on the net for the life of me. Any help would be appreciated.

Regulator specs

I am trying to get the specs on the regulator to see the total BTU input it can handle, so I may add up all gas fired appliances on the line in order to see if a new reg might be required.

Get in touch with

the gas company or if it is propane the propane provider they will be able to tell you.

What size is the gas meter on the job? Example an AL-425 will pass roughly 425,000 BTU's. Regulators will typically handle slightly more than the meter they are assigned to.

TYhe 3/16 th orifice is a standard house regulator size which if memory serves me will pass around 500 cubic feet per hour, that is equivalent to about 500,000 BTU's. That will handle most household demand unless you have installed a pool heater.

Tim, Just as an addition...

The actual line size for multiple units being supplied is also a factor. The reg. may be OK, but the line size itself may be causing a problem. As you stated, all things must be sized or considered. Ex: the 450,000 reg which can handle the load in the building, but the supply line size after the reg is 1" and it runs , say...100' before serving any load.,....Hmmm Now that is a problem. Charts recommend 1-1/2" for this scenario.
