Model 441-57S & Model 461-57S
The Sensus 461-57S and 441-57S medium pressure regulators are spring-operated models that incorporate a “roll-out” diaphragm, similar to the performance found in pilot-operated regulators.
The action of the roll-out diaphragm reduces “droop,” which is the fall off in outlet pressure as a spring regulator opens to increase flow. This makes the regulators’ exceptional performance possible. By offering near-pilot-operated regulator performance without a pilot, the 57S-series offers simplicity, dependability, and exceptionally fast response.
Both models are perfect for most intermediate and large-capacity applications:
- Gas distribution systems
- District regulator sets
- City gate stations
- Town border stations
- A wide variety of industrial applications.
These workhorses of the industry have been recognized for their dependable service for nearly 70 years.
Note: The 441-57S & 461-57S models are not yet available and will be transferred to USG in Phase 2.
