Depend on These Workhorses for High Performance and Fast Response

Our Model 441-57S and Model 461-57S medium pressure regulators are spring-operated regulators that incorporate a “roll-out” diaphragm, similar to the performance found in pilot-operated regulators.

The action of the roll-out diaphragm reduces “droop” (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 regulators offer 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
  • Monitoring
  • A wide variety of industrial applications.

These workhorses of the industry have been recognized for their dependable service for nearly 70 years.
