Has anyone run into a Spence valve for natural gas? It is 3 inch. Gas pressure is hunting on the outlet between 7 and 8 PSI. It serves (2) 500 HP boilers. We are doing a burner upgrade but are thinking of removing the Spence valve and installing (2) individual regulators for each boiler. Any input is appreciated.

    I'm familiar with H.P. Steam Spence valves but not for Natural gas. I would reach to your local gas utility Field Supervisor. They will tell you EXACTLY what they allow and will be the best way to. They'll probably give you specs too. These guys are usually always helpful in helping legit contractors..because they are the first and second responders on hack jobs mad Dog

    I think a seperate regulator for each boiler make more sense.

    Nothing wrong with Spence valves but they can be finiky
