Tartarini™ A/140 Series Spring-Loaded Pressure Reducing Regulators
Construction and performance features make the A/140 Series spring-loaded regulators the ideal choice in applications involving sudden changes in capacity or where the gas shutoff is solenoid-controlled as with domestic or industrial burners.
These regulators can be employed with natural, manufactured, and propane gas as well as air as long as they are adequately filtered and do not contain high percentages of aromatics.
