Sensus Regulator 461-X57 : 2″

Available Sizes
2″ Only

The 461-X57 is something 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 461057S Regulators.
The 461-X57 offers pilot performance with spring regulator simplicity. The “Roll-Out” diaphragm makes this outstanding performance possible by minimizing 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, thus, “droop” is reduced to insignificance. The result – smooth, constant pressure regulation. It comes amazingly close to the control performance of the pilot operated regulator.

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. The following explanation and the illustrations below show how this affects regular performance.
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 Regulator 461-8S/12S : 2″

Available Sizes
2″ Screwed Only

The Sensus Models 461-S, 461-8S and 461-12S are balanced valve, spring type regulators designed for distribution and
industrial applications where a single seat regulator is too small and the usual 2″ balanced valve regulators are too large. They are made in 2″ pipe sizes only and are used for:
Inlet Pressures to 175 psi
Outlet Pressures of 0 to 10 psi

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 is an unusually dependable regulator. It’s 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-Sis a excellent regulator for general usage and makes an excellent choice for such special applications as snap action on-off loads and monitoring service.

Sensus 243-8

Sensus Regulator 243-8-1 : 1-1/4″, 1-1/2″, 2″ and 2″ FLGD

Available Sizes
Regular: 1-1/4″, 1-1/2″, 2″
Flanged: 2″
No IRV

Sensus large capacity industrial service regulators are designed and built for commercial, industrial, and gas distribution use. As a result of the collar connection between the fully inter-changeable bodies and the diaphragm case, they have remarkable field versatility. They are right at home in such places as factories and foundries, district regulator stations, commercial laundries and laundromats, motels-hotels and apartments, bakeries, restaurants, schools, churches and hospitals.

The versatile 243 is used for all kinds of gas fueled equipment .. .boilers, burners, furnaces, ovens, heaters, kilns, engines, air conditioners, etc.
Remarkable field versatility results from the union connection between the fully interchangeable bodies and diaphragm-case assemblies. They are easy to install, adjust, inspect, and service in all piping arrangements.
Depth is affected by mounting position, flanged or screwed connections, diaphragm case size, and whether or not the unit is HP or standard.

Mounting Positions
These are multi-poised regulators, designed to that they can be mounted in any piping orientation.

Other Cases
243 Regulators are mainly used on natural gas. However, they perform equally as well on LP gas, nitrogen, dry CO2 , air and others. Contact us for special construction which may be available for certain corrosive gases.
