Sensus industrial combustion regulators combine new technology with modern design to provide
greater capacity, higher inlet pressure, more accurate performance, and faster speed of response.
In most cases, this will allow the use of a smaller regulator. Both the Model 121 and Model 122
regulators have high strength, corrosion resistant, die-cast diaphragm cases and cast iron bodies,
assuring a highly functional regulator at a better price. Both models incorporate soft seat valve
material plus a precision machined "knife edge" orifice to provide a positive, tight shutoff.
Sensus Metering Systems' industrial combustion regulators can be used in a variety of commercial
and industrial applications including: burners, boilers, furnaces, air heaters, kilns, or gas
engines where fast response will improve performance.

Sensus field and high pressure service regulators combine simplicity of design with rugged
construction, exceptional performance, and operational safety to provide dependable, flexible,
and economical answers for pounds-to-pounds pressure regulation applications.
The Model 046 family of high pressure regulators is easy to install, adjust, inspect, and service
in all piping arrangements. Typical applications include farm taps, field regulator applications,
and high pressure industrial air or gases.
The 2" Model 141-A regulator is designed for high pressure applications such as intermediate and
small volume loads on gas transmission lines. It is excellent for single and double stage reduction
ahead of the service regulator. The 141-A can be used on pipeline taps serving remote farm, domestic,
commercial, and industrial customers. It can also be used on other kinds of high pressure loads including
producer field work, high pressure burners and compressed air systems.

The Model 461-S and Model 441-S family of regulators are balanced valve, spring type regulators
designed for distribution and industrial applications. They are extremely dependable with simple
design, sturdy construction, and fast response. Service and adjustment are easy and overall
operation is stable and sensitive.
The 461-S, 461-8S, and 461-12S models are ideal for distribution and industrial applications
where a single seat regulator is too small and the usual 2" balanced valve regulators are too
large. Their large exit areas give them a broad capacity, making them applicable to a wide
variety of load handling requirements.
But, when large loads are the requirement, the model 441-S regulators have the larger bodies
and valves to deliver the gas. Large, flexible diaphragms combined with accurately calibrated
springs enable these large capacity regulators to produce precise pressure control while
maintaining a high level of sensitivity and stability. The combination of their fast response,
dependability, and accuracy make the 441-S models ideal for monitoring, as well as other
applications where speed and accuracy are significant.

The Model 461-57S and Model 441-57S are spring-operated regulators that incorporate a
"roll-out" diaphragm which approximates the performance of a pilot-operated regulator. The
roll-out diaphragm makes this exceptional performance possible because its action reduces
"droop" to a minimum. By offering near pilot-operated performance without a pilot, the 57S
regulators offer the advantages of simplicity, dependability, freedom from freeze-up, and
exceptionally fast response.
Both models are perfect for most intermediate and large capacity applications including gas
distribution systems, district regulator sets, city gate stations, town border stations,
monitoring, and a wide variety of industrial applications. These workhorses of the industry
have provided dependable service for over 60 years.

The Model 461-X57 and Model 441-X57 are unique high pressure, large capacity spring operated
regulators that incorporate the same "roll-out" diaphragm principal that achieved such success
in the widely used 461-57S and 441-57S regulators. Both regulators offer pilot type performance
with spring-operated regulator simplicity. The roll-out diaphragm makes this exceptional
performance possible because its action reduces "droop" to a minimum. Offering fast response
and ease of installation, adjustment, and servicing, the 461-X57 and 441-X57 models are perfect
for most high pressure, large capacity applications including high pressure regulator sets, gas
distribution systems, town border stations, transmission systems, monitoring, and most high
pressure large capacity industrial applications.

Sensus Model 243-RPC regulators are rugged, reliable pilot-operated regulators that incorporate
the same relay operation principle as the well-known 441-VPC. They offer exceptionally precise
regulation and are accurate to within ± 0.5% (absolute outlet pressure) from minimum to wide-open
flow. The 243-RPC pilot-operated regulator is designed for fixed factoring, pressure factor
measurement, pressure compensated metering, and other applications requiring exceptionally
precise pressure control.

Sensus Model 441-VPC pilot operated regulators are designed to fit your specialized large
capacity regulator needs. These regulators provide sensitivity, high capacity, and a high degree
of accuracy for fixed factor billing on modulating loads. The 441-VPC incorporates Sensus
Metering Systems' extremely successful 441 series regulators with a pilot for sensing regulated
pressure, and for controlling overall operation. Use of a 441-VPC is especially recommended
where extremely close control is required. These regulators can be remotely controlled by using
air loading in the pilot upper case. Because of the exceptionally close control offered by the
441-VPC family, they are ideal for applications such as district and station regulator sets,
distribution systems, transmission systems, compressor stations, and large capacity industrial
combustion systems where a high degree of accuracy is required. Note, solenoid load applications
are not recommended. Load limiting regulators on the inlet supply to the pilot will improve the
accuracy of these products.
