Sensus Low Pressure Gas Regulator 441-S
Sensus 441 S Industrial Low Pressure Gas Regulator
 

The 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.

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.

Available Pipe Sizes:
2" NPT Screwed only
2", 3", 4" Flanged

Sensus 461-S Industrial Low Pressure Large Capactiy Gas Regulator
 

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. Contoured body passages for reducing turbulence and large exit areas give them a broad capacity capability thus making them applicable to a wide variety of load handling requirements.

The 461-S and 461-12S are unusually dependable regulators. Their design is simple, the construction is sturdy. Servicing and adjustment are easy, response is fast. The overall operation is stable and sensitive, and they provide exceptionally precise regulation.

The 461-S, 461-8S and 461-12S are excellent regulators for general usage. They also make an excellent choice for such special applications as snap action on-off loads and monitoring service.

Available Pipe Size: 2" NPT Screwed and Flanged
Inlet Pressures to 175 psi
Outlet Pressures of 0 to 10 psi

Sensus Medium Pressure Gas Regulator 441-57S
Sensus 441-57S Industrial Medium Pressure Gas Regulator
 

The Model 441-57S is a spring-operated regulator 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.

This model is 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. This regulator has provided dependable service for over 60 years.

Available Pipe Sizes:
2", 3", 4" and 6" NPT Screwed

The heart of the Model 461-57S is the “Roll-Out” diaphragm. The 461-57S is a spring regulator with performance which approximates that of a pilot operated regulator. The “Roll-out” Diaphragm makes this exceptional performance possible because its action reduces “droop” to a minimum (“droop” being fall off in outlet pressure as a spring regulator opens to increase flow.)

The action of the “Roll-Out” diaphragm differs from that of the conventional diaphragm in the manner in which the change in effective area occurs. Where the effective area of a conventional diaphragm would increase as the regulator opens, the “Roll-Out” area decreases. Conversely, where the area of the conventional diaphragm decreases during closing, the “Roll-Out” area increases.

Spring type regulators are operated by the inter-action between spring and diaphragm. The compressive force of the spring works to open the regulator and is balanced by the opposing force of outlet pressure on the diaphragm which provides the closing force.

As the regulator opens, the compressive force of the spring decreases. However, as this spring force decreases, there must be a corresponding decrease in the opposing force from the diaphragm. For this opposing diaphragm force to decrease, either the effective area or the outlet pressure must decrease. Herein is the essential difference; with a conventional diaphragm the outlet pressure must decrease, where as with the “Roll-Out” diaphragm it is the effective area that decreases, permitting the outlet pressure to remain constant.

The operation actually is quite simple, yet the action of the “Roll-Out” diaphragm is so effective that “droop” is practically eliminated.

The Model 461-57S provides constant pressure regulation not previously possible in a “pounds to pounds” spring regulator. It approaches pilot performance, and, in addition, offers the further advantages of simplicity, dependability, freedom from freeze-up, and exceptionally fast response.

Sensus 441 x57 Industrial High Pressure Large Capacity Gas Regulator
 

The 441-X57 is unique in a high pressure regulator. It features the same “Roll-Out” diaphragm principle that has achieved such remarkable success in the widely used 441-57S and 461-57S Regulators.

The 441-X57 offers pilot performance with spring regulator simplicity. The “Roll-Out” diaphragm makes this outstanding performance possible by eliminating that old gremlin-- “Droop.”

“Droop” means rough regulation, wide fluctuation in pressure control as flow varies. It is the result of spring effect plus diaphragm effect.

The “Roll-Out” diaphragm changes this. By eliminating diaphragm effect and neutralizing spring effect, “droop” is reduced to insignificance. The result--smooth, constant pressure regulation. It comes amazingly close to the control performance of the pilot operated regulator.
