Model 441-X57 & Model 461-X57
The Sensus 461-X57 and 441-X57 regulators are unique high-pressure, large-capacity, spring-operated regulators. These high-pressure regulators incorporate the same roll-out diaphragm principal that is widely used in the Sensus 461-57S and 441-57S models.
Both regulators offer pilot-type performance with spring-operated regulator simplicity. The action of the roll-out diaphragm makes the regulators’ exceptional performance possible by reducing droop, the falloff in outlet pressure as a spring regulator opens to increase flow, to a minimum.
These models feature fast response and ease of installing. They are also simple to adjust and service. The 461-X57 and 441-X57 are both perfect for most high-pressure, large-capacity applications. This includes high-pressure regulator sets, gas distribution systems, town border stations, transmission systems and most industrial applications.
The 461-X57 and 441-X57 regulators can also be used as monitors and quickly assume control if a failure in the operating regulator allows the outlet pressure to exceed its set point. No modifications are required for use as a monitor, even if used as a monitor for other types of regulators.
Note: The 441-X57 & 461-X57 models are not yet available and will be transferred to USG in Phase 2.
