Sensus Regulator Series 122-8, 122-12

For an unbeatable combination of capacity, performance and economy, install the Sensus Model 122 industrial combustion type gas pressure regulator.

Streamlined body passages provide large capacity. Carefully engineered internal sensing produces accurate pressure control without an external control line. And, just in case a particular application necessitates one, a handy tap on the 122 makes connection into an external control line a simple matter.

Diaphragm cases are high strength, corrosion resistant die-cast aluminum alloy. This makes a better looking regulator at a better price. In addition, on 1″ through 2½” sizes a large area double acting damper in the vent assures fast speed of response while maintaining stability, which is just the thing for those troublesome “snap-acting” loads.

Soft seats plus a precision machined “knife-edge” orifice provide positive tight shutoff, and the orifice is removable.
