Sensus Regulator Series 121-8, 121-8HP, 121-12, 121-16
Sensus 121 industrial gas regulator

The Model 121 is a new dimension in spring regulator capability, offering spring regulator dependability, simplicity and economy. New technology plus contemporary design provides greater capacity, higher inlet pressure, more accurate performance and faster response, with resulting economy.

Use the 121 for commercial and industrial applications: burners, boilers, furnaces, air heaters, kilns, gas engines and benefit from its fast response. Use it also as a large capacity supply regulator on commercial or industrial service lines, or as a small district regulator.
It’s excellent for primary control or monitoring — use it for either or both. The 121 is actually a whole new family of regulators – standard regulator, zero governor or atmospheric regulator, differential regulator, back pressure regulator, or relief valve, vacuum regulator and vacuum breaker.

Compatible with natural gas, propane, LPG, air nitrogen, etc. Special material available for certain corrosive gases

Available Pipe Sizes, depending on model:
3/4", 1", 1-1/4" 1-1/2", 2", 2-1/2", 3", 4" NPT Screwed

Sensus Regulator Series 122-8, 122-12
Sensus 243-12 industrial gas regulator

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 orifi ce is removable.

Available Pipe Sizes, depending on model:
1", 1-1/4", 1-1/2", 2", 2-1/2" NPT Screwed
