Installation and Maintenance Instructions
Model 461-57S Regulator
Where outlet piping increases in size near the regulator, its
generally preferable to locate the control connection in the larger size.
The 1/4" union 20 contains a small orifice, approximately
1/16" diameter. This orifice should not be removed. Also,
make certain this orifice is open and free of foreign material.
CAUTION
The diaphragm case vent must be positioned to protect against
flooding, drain water, ice formation, traffic, tampering, etc. The vent
must be protected against nest building animals, bees, insects, etc., to
prevent vent blockage and minimize chances for foreign material from
collecting in the vent side of the regulator diaphragm.
4Check all connections for leaks.
5Put the regulator into operation as follows: (See Figure 1)
1. Slowly open the downstream control line valve A.
2. Slowly open the downstream block valve B.
3. Very slowly open the upstream block valve C.
4. Set the adjusting screw 2for the required outlet pressure.
Turn it clockwise to increase the pressure and
counterclockwise to decrease it. Only make this
adjustment when gas is actually flowing through the regulator.
CAUTION
Turn gas on very slowly. If an outlet stop valve is used, it
should be opened first. Do not overload diaphragm with a
sudden surge of inlet pressure. Monitor the outlet pressure
during start-up to prevent an outlet pressure overload.
5. After adjustment is complete, the locknut 3 should be
tightened firmly and the seal cap 1 replaced.
6To shut down, carefully close valves C, B, and Ain that order.
Introduction
The heart of the Model 461-57S is the “Roll-Out” Diaphragm. The
461-57S is a spring regulator with performance which approxi-
mates that of a pilot operated regulator. The “Roll-Out” Diaphragm
makes this exceptional performance possible because its unique
action reduces “droop” to a minimum (“droop” being fall off in
outlet pressure as a spring regulator opens to increase flow).
Installation and Start-Up
1Thoroughly purge inlet piping to remove dirt and debris which
could damage the regulator or impair its operation. If this
cannot be done, a filter or strainer should be installed ahead
of the regulator (see Sensus Bulletin RDS-1498, Regulator
Pressure Ratings). Make certain that regulator is free of any
dirt or foreign matter that might have collected.
2Place regulator in the line with high pressure connected to the
inlet side (be sure that shipping screens or covers, if used, are
removed from the inlet and outlet).
On flanges, tighten bolts evenly.
Where required, the regulator may be inverted. It may also be
installed in a vertical line. However, if installed in a vertical
line, there could be excessive wear in anti-friction bushing.
3From the 1/4" union 20 extend pipe or tubing to the control
connection into the oulet piping. (See Figure 1 on page 2.)
This control piping should not be less than 1/4" in size and
should be adequately protected against breakage (regulators
go wide open if the control line is broken.)
CAUTION
It is the user's responsibility to assure that all regulator vents and/or
vent lines exhaust to a non-hazardous location away from ANY
POTENTIAL sources of ignition. Where vent lines are used, it is the
user's responsibility to assure that each regulator is individually vented
and that common vent lines ARE NOT used.
The regulator will work to deliver the pressure, for which it is
adjusted, at that point in the outlet piping where the control
connection is located.
In general the control connection should be at least eight pipe
diameters from the regulator and should be in as straight a
run of pipe as possible.
The control connection should be clean and smooth, free of
rough edges, welding “icicles”, etc.

Servicing and Adjustment
General Notes (see Illustration on page7)
1Make sure the regulator is entirely depressured before servicing.
2A quick visual inspection of the valve can be made by
removing inspection plates 33 from the sides of the body.
These also provide greatly improved access to the valve when
servicing or adjusting.
3The diaphragm 11d, the springs 9, and all other parts from
the diaphragm up (except the 11h stud) are interchangeable
with the Model 441-57S Regulator. Valve and body parts are
interchangeable with other 461 Regulators
(461-S, 461-X57, 1100, 1200, 461-2100).
4Use lubricants sparingly and with care to avoid exposing tacky
surfaces to the gas stream. Such surfaces could cause dirt
accumulation on close clearance parts.
Use moly or silicone type lubricants. Avoid the use of
petroleum base types.
Lubricate the stem 12b, guide 12j and stem O-rings 12a
& 12n with dry silicon lubricant to help assure free
movement and a tight seal.
An application of lubricant to other O-rings and the tetraseals
in the regulator will also help assure their tightness.
5When using double seat balanced valve assembly, bushing 13
must be screwed firmly into place. When using single seat
balanced valve assembly, bushing 13 must be removed.
To Service Double Seat Balanced Valve Assembly
1Remove seal cap 1, back off adjusting screw 2, remove
housing cover 6, and remove spring 9.
2Remove bottom inspection plate 14, and unscrew valve
assembly intact from diaphragm assembly (12b unscrews
from 11h).
3Unscrew orifice 18 with socket wrench (1-1/2" hex, deep
socket). Remove orifice 18 and valve assembly intact
through bottom opening.
4If valve assembly and orifice are alright, screw orifice 18
firmly into place. Replace without disturbing set screw 12g.
Top end of 12b screws into 11h until it bottoms and should
then be backed off 1/2 to 1 full turn.
5If new parts are needed, disassemble valve assembly by
loosening set screw 12g and unscrewing 12h from 12b, and
then unscrewing nut 12e and part 12j.
6Replace parts as required, then reassemble upper half valve
assembly (parts 12a, 12b, 12c, 12d, 12e) and lower half
(parts 12f, 12g, 12h, 12c, 12d, 12j).
7Insert through bottom opening:
a. upper half valve assembly - screw 12b onto 11h until
it bottoms then back off 1/2 to 1 full turn.
b. orifice 18 - screw firmly into place.
c. lower half valve assembly - screw onto upper half
by 3 or 4 turns (12h screws onto 12b).
8Make the valve lock-up adjustment. Seat the upper valve
against orifice 19 while screwing up the lower half valve
assembly (12h screws onto 12b until the lower valve is
seated against 18). Then, firmly tighten set screw 12g.
a. To seat the upper valve against orifice 19, either reach
it through the body side opening or remove diaphragm
assembly and pull top end of stem 12b upwards.
b. Tighten 12g with screwdriver through body side
opening. If necessary, turn the entire valve assembly
(carefully – do not disturb adjustment to face 12g
toward side opening).
c. 12g must tighten against flat area at top of 12h to
correctly lock the adjustment.
9Screw entire valve assembly up (top of 12b screws onto
lower end of 11h until it bottoms), then back off 1/2 to 1
full turn - this is important.
10 Complete assembly as per steps 6 thru 10 under
“To Assemble 461-57S”.

and disassemble.
5When reassembling, be sure that fabric side and gasket of
diaphragm is toward the vent side of the regulator and the
rubber side of diaphragm toward the pressure side. The
gasket is always placed on the spring side of diaphragm.
6To minimize rolling friction and prevent sticking, coat the
fabric side of the diaphragm with Molycote, or equivalent
graphite based lubricant, before installation Screw diaphragm
assembly back into place. (11h screws into 12b until it
bottoms), then back off 1/2 to 1 full turn - this is important.
7Form roll into roll-out diaphragm 11d, then carefully reinstall
upper diaphragm case 10. Diaphragm must not be pinched
between upper and lower cases, 10 and 21. Also,
roll-out loop must be uniformly full and even. It should be in
place as shown of the cross-section drawing. Tighten
bolts 23 and nuts 22 evenly.

CAUTION
Regulators are pressure control devices with numerous moving
parts subject to wear that is dependent upon particular
operating conditions. To assure continuous satisfactory
operation, a periodic inspection schedule must be adhered to
with the frequency of inspection determined by the severity of
service and applicable laws and regulations.
