The Sensus 121 and 122 regulators are industrial combustion regulators. They can help achieve greater capacity, higher inlet pressure, more accurate performance and a faster response for higher volume commercial and industrial applications.
These regulators provide an unbeatable combination of capacity, performance, and economy. In most applications, their design allows you to use a smaller regulator for primary control or monitoring, or both.
Both the 121 and 122 are highly functional regulators that feature die-cast diaphragm cases and cast iron bodies. This makes them strong and corrosion resistant. Both models incorporate soft-seat valve material, plus a precision-machined “knife edge” orifice for a positive, tight shutoff.
They can be used in a variety of commercial and industrial applications including burners, boilers, furnaces, air heaters and kilns. These regulators also work well for gas engines where fast response improves overall performance.
