Our Model 461-X57 and Model 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 so successful in our widely used 461-57S and 441-57S medium-pressure regulator 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 fall off in outlet pressure as a spring regulator opens to increase flow) to a minimum. With fast response and ease of installing, adjusting and servicing, models 461-X57 and 441-X57 are 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. Model 461-X57 and Model 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.
