Elastomers: Chemical Names and Uses
NBR - Nitrile Rubber, also called Buna-N, is a copolymer of
butadiene and acrylonitrile. Nitrile is recommended for: general
purpose sealing, petroleum oils and uids, water, silicone greases
and oils, di-ester based lubricants (such as MIL-L-7808), and
ethylene glycol based uids (Hydrolubes). It is not recommended
for: halogenated hydrocarbons, nitro hydrocarbons (such as
nitrobenzene and aniline), phosphate ester hydraulic uids
acids, ozone, and automotive brake uid. Its temperature range is
-60° to 225°F (-51° to 107°C), although this would involve more
than one compound and would depend upon the stress state of the
component in service.
EPDM, EPM - Ethylenepropylene rubber is an elastomer prepared
from ethylene and propylene monomers. EPM is a copolymer of
ethylene and propylene, while EPDM contains a small amount
of a third monomer (a diene) to aid in the curing process. EP is
recommended for: phosphate ester based hydraulic uids, steam to
400°F (204°C), water, silicone oils and greases, dilute acids, dilute
alkalis, ketones, alcohols, and automotive brake uids. It is not
recommended for: petroleum oils, and di-ester based lubricants.
Its temperature range is -60° to 500°F (-51° to 260°C) (The high
limit would make use of a special high temperature formulation
developed for geothermal applications).
FKM- This is a uoroelastomer of the polymethylene type having
substituent uoro and peruoroalkyl or peruoroalkoxy groups
on the polymer chain. Viton® and Fluorel® are the most common
trade names. FKM is recommended for: petroleum oils, di-ester
based lubricants, silicate ester based lubricants (such as MLO
8200, MLO 8515, OS-45), silicone uids and greases, halogenated
hydrocarbons, selected phosphate ester uids, and some acids. It
is not recommended for: ketones, Skydrol 500, amines (UDMH),
anhydrous ammonia, low molecular weight esters and ethers, and
hot hydrouoric and chlorosulfonic acids. Its temperature range is
-20° to 450°F (-29° to 232°C) (This extended range would require
special grades and would limit use on each end of the range.).
CR- This is chloroprene, commonly know as neoprene, which
is a homopolymer of chloroprene (chlorobutadiene). CR is
recommended for: refrigerants (Freons, ammonia), high aniline
point petroleum oils, mild acids, and silicate ester uids. It is
not recommended for: phosphate ester uids and ketones. Its
temperature range is -60° to 200°F (-51° to 93°C), although this
would involve more than one compound.
NR- This is natural rubber which is a natural polyisoprene,
primarily from the tree, Hevea Brasiliensis. The synthetics
have all but completely replaced natural rubber for seal use.
NR is recommended for automotive brake uid, and it is not
recommended for petroleum products. Its temperature range is
-80° to 180°F (-62° to 82°C).
FXM- This is a copolymer of tetrauoroethylene and propylene;
hence, it is sometimes called PTFE/P rubber. Common trade
names are Aas® (Asahi Glass Co., Ltd) and Fluoraz® (Greene,
Tweed & Co.). It is generally used where resistance to both
hydrocarbons and hot water are required. Its temperature range is
20° to 400°F (-7° to 204°C).
ECO- This is commonly called Hydrin® rubber, although that is a
trade name for a series of rubber materials by B.F. Goodrich. CO
is the designation for the homopolymer of epichlorohydrin, ECO is
the designation for a copolymer of ethylene oxide and chloromethyl
oxirane (epichlorohydrin copolymer), and ETER is the designation
for the terpolymer of epichlorohydrin, ethylene oxide, and an
unsaturated monomer. All the epichlorohydrin rubbers exhibit
better heat resistance than nitrile rubbers, but corrosion with
aluminum may limit applications. Normal temperature range is
(-40° to 250°F (-40° to 121°C), while maximum temperature ranges
are -40° to 275°F (-40° to 135°C) (for homopolymer CO) and
-65° to 275°F (-54° to 135°C) (for copolymer ECO and
terpolymer ETER).
FFKM - This is a peruoroelastomer generally better known as
Kalrez® (DuPont) and Chemraz® (Greene, Tweed). Peruoro
rubbers of the polymethylene type have all substituent groups on
the polymer chain of uoro, peruoroalkyl, or peruoroalkoxy
groups. The resulting polymer has superior chemical resistance
and heat temperature resistance. This elastomer is extremely
expensive and should be used only when all else fails. Its
temperature range is 0° to 480°F (-18° to 249°C). Some materials,
such as Kalrez® 1050LF is usable to 550°F (288°C) and
Kalrez® 4079 can be used to 600°F (316°C).
FVMQ - This is uorosilicone rubber which is an elastomer that
should be used for static seals because it has poor mechanical
properties. It has good low and high temperature resistance and
is reasonably resistant to oils and fuels because of its uorination.
Because of the cost, it only nds specialty use. Its temperature
range is -80° to 400°F (-62° to 204°C).
VMQ - This is the most general term for silicone rubber. Silicone
rubber can be designated MQ, PMQ, and PVMQ, where the Q
designates any rubber with silicon and oxygen in the polymer
chain, and M, P, and V represent methyl, phenyl, and vinyl
substituent groups on the polymer chain. This elastomer is used
only for static seals due to its poor mechanical properties. Its
temperature range is -175° to 600°F (-115° to 316°C) (Extended
temperature ranges require special compounds for high or
low temperatures).

Regulator Tips
664
Te c h n i c a l
1. All regulators should be installed and used in accordance with
federal, state, and local codes and regulations.
2. Adequate overpressure protection should be installed to protect
the regulator from overpressure. Adequate overpressure
protection should also be installed to protect all downstream
equipment in the event of regulator failure.
3. Downstream pressures signicantly higher than the regulator's
pressure setting may damage soft seats and
other internal parts.
4. If two or more available springs have published pressure
ranges that include the desired pressure setting, use the spring
with the lower range for better accuracy.
5. The recommended selection for orice diameters is the
smallest orice that will handle the ow.
6. Most regulators shown in this application guide are generally
suitable for temperatures to 180°F (82°C). With high
temperature uoroelastomers (if available), the regulators
can be used for temperatures to 300°F (149°C). Check
the temperature capabilities to determine materials and
temperature ranges available. Use stainless steel diaphragms
and seats for higher temperatures, such as steam service.
7. The full advertised range of a spring can be utilized without
sacricing performance or spring life.
8. Regulator body size should not be larger than the pipe size. In
many cases, the regulator body is one size smaller than the
pipe size.
9. Do not oversize regulators. Pick the smallest orice size or
regulator that will work. Keep in mind when sizing a station
that most restricted trims that do not reduce the main port size
do not help with improved low ow control.
10. Speed of regulator response, in order:
• Direct-operated
• Two-path pilot-operated
• Unloading pilot-operated
• Control valve
Note: Although direct-operated regulators give the fastest
response, all types provide quick response.
11. When a regulator appears unable to pass the published
ow rate, be sure to check the inlet pressure measured at
the regulator body inlet connection. Piping up to and away
from regulators can cause signicant owing pressure losses.
12. When adjusting setpoint, the regulator should be owing at
least ve percent of the normal operating ow.
13. Direct-operated regulators generally have faster response to
quick ow changes than pilot-operated regulators.
14. Droop is the reduction of outlet pressure experienced by
pressure-reducing regulators as the ow rate increases. It is
stated as a percent, in inches of water column (mbar) or in
pounds per square inch (bar) and indicates the difference
between the outlet pressure setting made at low ow rates
and the actual outlet pressure at the published maximum
ow rate. Droop is also called offset or proportional band.
15. Downstream pressure always changes to some extent when
inlet pressure changes.
16. Most soft-seated regulators will maintain the pressure within
reasonable limits down to zero ow. Therefore, a regulator
sized for a high ow rate will usually have a turndown ratio
sufcient to handle pilot-light loads during off cycles.
17. Do not undersize the monitor set. It is important to realize
that the monitor regulator, even though it is wide-open,
will require pressure drop for ow. Using two identical
regulators in a monitor set will yield approximately
70 percent of the capacity of a single regulator.
18. Diaphragms leak a small amount due to migration of gas
through the diaphragm material. To allow escape of this gas,
be sure casing vents (where provided) remain open.
19. Use control lines of equal or greater size than the control tap
on the regulator. If a long control line is required, make it
bigger. A rule of thumb is to use the next nominal pipe size
for every 20 feet (6,1 m) of control line. Small control
lines cause a delayed response of the regulator, leading
to increased chance of instability. 3/8-inch (9,5 mm) OD
tubing is the minimum recommended control line size.
20. For every 15 psid (1,0 bar d) pressure differential
across the regulator, expect approximately a one degree
drop in gas temperature due to the natural refrigeration
effect. Freezing is often a problem when the ambient
temperature is between 30° and 45°F (-1° and 7°C).
21. A disk with a cookie cut appearance probably means you had
an overpressure situation. Thus, investigate further.
22. When using relief valves, be sure to remember that the
reseat point is lower than the start-to-bubble point. To
avoid seepage, keep the relief valve setpoint far enough
above the regulator setpoint.
Regulator Tips
665
Te c h n i c a l
23. Vents should be pointed down to help avoid the accumulation
of water condensation or other materials in the spring case.
24. Make control line connections in a straight run of pipe about
10 pipe diameters downstream of any area of turbulence,
such as elbows, pipe swages, or block valves.
25. When installing a working monitor station, get as much
volume between the two regulators as possible. This
will give the upstream regulator more room to control
intermediate pressure.
26. Cutting the supply pressure to a pilot-operated regulator
reduces the regulator gain or sensitivity and, thus, may
improve regulator stability. (This can only be used with two
path control.)
27. Regulators with high ows and large pressure drops generate
noise. Noise can wear parts which can cause failure and/or
inaccurate control. Keep regulator noise below 110 dBA.
28. Do not place control lines immediately downstream of rotary
or turbine meters.
29. Keep vents open. Do not use small diameter, long vent lines.
Use the rule of thumb of the next nominal pipe size every
10 feet (3,1 m) of vent line and 3 feet (0,9 m) of vent line
for every elbow in the line.
30. Fixed factor measurement (or PFM) requires the regulator
to maintain outlet pressure within ±1% of absolute pressure.
For example: Setpoint of 2 psig + 14.7 psia = 16.7 psia x
0.01 = ±0.167 psi. (Setpoint of 0,14 bar + 1,01 bar = 1,15 bar x
0,01 = ±0,0115 bar.)
31. Regulating Cg (coefcient of ow) can only be used for
calculating ow capacities on pilot-operated regulators.
Use capacity tables or ow charts for determining a direct-
operated regulator’s capacity.
32. Do not make the setpoints of the regulator/monitor too close
together. The monitor can try to take over if the setpoints are
too close, causing instability and reduction of capacity. Set
them at least one proportional band apart.
33. Consider a butt-weld end regulator where available to lower
costs and minimize ange leakages.
34. Do not use needle valves in control lines; use full-open
valves. Needle valves can cause instability.
35. Burying regulators is not recommended. However, if you
must, the vent should be protected from ground moisture
and plugging.

For pipe lengths other than 100 feet, the pressure drop is proportional to the length. Thus, for 50 feet of pipe, the pressure drop is approximately one half the value given in the table or 300 feet,
three times the given value, etc.
Velocity is a function of the cross sectional ow area; thus, it is constant for a given ow rate and is independent of pipe length.

wall tube submerged in water to a depth of from 0.12 to 0.24 inch (3 to 6 mm). The tube end shall be cut square and smooth with no chamfers or burrs and the tube axis shall be
perpendicular to the surface of the water. Other apparatus may be constructed and the number of bubbles per minute may differ from those shown as long as they correctly indicate the
ow in ml per minute.
2. If valve seat diameter differs by more than 0.08 inch (2 mm) from one of the valves listed, the leakage rate may be obtained by interpolation assuming that the leakage rate varies as the
square of the seat diameter.

Flange, Valve Size, and Pressure-Temperature
Rating Designations
Sizes of ASME anges are designated as NPS (for “nominal
pipe size”). The nominal size is based on inches, but the units are
not required in the designation. For example: NPS 2 is the size.
Pressure ratings are designated by class. For example, CL150 is
the rating. ASME designations replace ANSI designations.
Sizes of EN and ISO anges are designated with DN (for “nominal
diameter”). The nominal diameter is based on millimeters, but
the units are not included in the designation. For example: DN 50
is the size. Pressure ratings are designated by PN (for “nominal
pressure”). For example PN 40 is the pressure rating. EN and ISO
designations replace DIN designations through PN 100.
ASME B16.5 anges will mate with EN 1759 anges but not with
EN 1092 anges (formerly DIN anges). ASME B16.5 anges
will mate with most ISO 7005 anges.
Common size designations in wide use are shown in the table below.
A summary of ange terminology is shown in the table below, and
equivalency of anges is shown in the table on the following page.
Pipe Thread Standards
There are three pipe thread standards that are accepted globally:
• G Series, ISO 228-1: Pipe threads for use where pressure-tight
joints are not made on the threads. The internal and external
threads are not tapered but are parallel or straight.
• R Series, ISO 7/1: Pipe threads for use where pressure-tight
joints are made on the threads. The internal thread is parallel
(straight) or tapered; external is always tapered.
Notes
Japanese (JIS) valves and anges are designated according to
JIS standards.
European Norm ange types, such as at-face and raised-face
are designated Type A, Type B, Type C. These types do not
correspond to the DIN 2526 Form A, Form D, etc., designations.

Wear and Galling Resistance Chart of Material Combinations (continued)
1. A uid is said to ow through the run of a tee when the ow is straight through the tee with no change of direction.
2. A tee is said to be reduced 1/4 if the internal area of the smaller connecting pipe is 25% less than the internal area of the larger connecting pipe.
Identication, wall thickness and weights are extracted from ASME B36.10 and B39.19.
The notations STD, XS, and XXS indicate Standard, Extra Strong, and Double Extra Strong pipe, respectively.
Transverse internal area values listed in “square feet” also represent volume in cubic feet per foot of pipe length.
