SEAT mATERIALS

EPDm (Peroxide Cured)

EPDM is the abbreviated name or Ethlene Proplene DieneMonomer. In general industr, one ma see other abbreviations or

trade names used in lieu o EPDM such as EPT, Nordel, ECD, or

EPR. Tpicall these are the same materials as EPDM.

EPDM is a standard seat material oered in Bra resilient-seated

butterf valves. It is the most universal and economical o seat

materials oered b Bra; that is, it ma be used in a wider range

o applications than BUNA-N. O important signicance also is

the act all EPDM seat materials sold b Bra are Food Grade.

Bras EPDM Food Grade seats are perectl suitable or sanitar

applications as well as standard industrial uses. EPDM is also

available as a covering or Series 20 discs.

BUNA-N (Black & White)BUNA-N is the commonl used name or Nitrile snthetic rubber.

Nitrile is a copolmer o acrlonitrile and butadiene. BUNA-N is

sometimes reerred to as NBR, Nitrile, or Hcar. BUNA-N is an

excellent general purpose seat material which is particularl suitable

or hdrocarbon service. BUNA-N is a standard Bra seat material

and is Food Grade; thus suitable or sanitar applications. Note,

BUNA-N is also available as a covering or Series 20 disc stems.

FKmFKM is the ASTM D1418 designation or Fluorinated Hdrocarbon

Elastomers (Fluoroelastomers) such as Viton (DuPont). FKM has

some outstanding characteristics such as improved acid, oil, and

temperature resistance over standard seat materials.

PoLyURETHANEUrethane seats are primaril used or their abilit to resist abrasive

wear. Urethane can be used on a reasonabl broad range o services.

Urethane will withstand severe impact, recover its original shape

ater distortion and resist abrasion better than other elastomers such

as EPDM and BUNA-N.

Seat material availability depends on valve size & series.Please consult your local Bray representativefor your specic application.

SEAT mATERIALS

PTFE LINED EPDm(Standard or High-temp)

PTFE lined EPDM seat consists o a PTFE liner which orms theaces and the fow wa o the seat, and is molded on to an EPDM

elastomer backing. Onl the inert non-stick PTFE liner surace is

exposed to the line media. The EPDM backing acts as a resilient

support to the relativel rigid PTFE. These seats are generall used

where BUNA-N and EPDM seats are not chemicall suitable

especiall in corrosive services.

VIRgIN PTFEAll Bra PTFE seats and encapsulated discs are molded rom pure

virgin PTFE material to the ollowing specications: thickness 3

mm, specifc gravity 2.16, crystallinity 68%. PTFEs inherenmolecular bonding strength gives an excellent chemical, high

temperature and tear resistance. Sintered processed PTFE oers

lower permeabilit than melt processed materials such as PFA. These

properties combined with Bras stringent material specications

provide optimum protection against permeation o the line media.

coNDUcTIVE PTFEBra Conductive PTFE seats and discs are available or

installation in areas o the plant where explosion protection

is important. This material was designed to prevent harmul

electrostatic discharge. For the ultimate in saet and reliabilitBra has combined electrostatic discharge protection and the

excellent chemical resistance properties o PTFE. The conductive

PTFE seat and the disc has a minimum thickness o 1/8 (3 mm)

providing optimum protection against permeation o the line media.

UHmWPEUHMWPE seats and discs eature exceptional chemical resistance

and are the ideal choice or highl abrasive chemical applications

The natural abilit o the UHMWPEs high molecular weight to

repel solids prevents in-line particles rom damaging the valves sea

suraces. An economical and high perormance choice or abrasivechemical services.

Seat material availability depends on valve size & series.

Sanitar & Chemical applications

One-piece disc/stem

High CV, low pressure drop

STEm BUSHINg: Non-corrosive, heav dut acetalbushing absorbs actuator side thrust.

STEm SEAL: Double U cup seal design is sel-adjusting and givespositive sealing in both directions and prevents external substances

rom entering the stem bore.

DISc / STEm: One-piece design. The disc edge is sphericallmachined and hand polished to produce a bubble-tight shut o, minimum

torque, and longer seat lie. The disc/stem design inherentl provides

complete protection rom particle entrapment and bacterial deca,

protection that is required or sanitar perormance. For

superior erosion and abrasion resistance, the one-piece

disc/stem is ull encased in either EPDM or BUNA-N.The thin disc prole provides a much higher Cv (up

to 50% greater than most through-stem designs) and

greater pressure recover, thus resulting in lower

pressure drops and a more energ-ecient valve.

PRImARy & SEcoNDARy SEALS: Theseseals prevent line media rom coming in contact

with the stem or bod.PrimarySeal is achieved

b an intererence t o the molded seat fat

with the disc hub. Secondary Seal is created

because the stem diameter is greater than the

diameter o the seat stem hole.

SEAT: Bras tongue and groove seat design

lowers torque and provides complete isolationo fowing media rom the bod. The seat also

eatures a molded O-ring which eliminates the

use o fange gaskets.

BoDy: Two-piece waer or lug stle allowsor ease o assembl and maintenance. Nlon 11

BS 10 Tables D and E, BS 4504 NP 10/16, DIN ND 10/16, AS 2129

and JIS10. In addition, the valves are designed to compl with

ISO 5752 - Table 2 (EN 558 Table 13) ace-to-ace and ISO

5211 actuator mounting fanges. Thereore, one valve

design can be used in man dierent world markets.

STEm RETAININg ASSEmBLy:The stem is

retained in the bod b means o a unique Stainless

Steel Spirolox retaining ring, a thrust washer

and two C-rings, manuactured rom brass as

standard, stainless steel upon request. The

retaining ring ma be easil removed with

a standard hand tool. The stem retaining

assembl prevents unintentional removal

o the stem during eld service.

STEm BUSHINg: Non-corrosive,heav dut acetal bushing absorbs

actuator side thrusts.

STEm SEAL: Double U cupseal design is sel-adjusting, gives

positive sealing in both directions, andprevents external substances rom entering

the stem bore.

ExTENDED NEcK: Extended neck lengthallows or 2 o piping insulation and is easil

accessible or mounting actuators.

PRImARy & SEcoNDARy SEALS: These seals prevent line mediarom coming in contact with the stem or bod. PrimarySeal is achieved

b an intererence t o the molded seat fat with the disc hub.Secondary

Seal is created because the stem diameter is greater than the diameter o

the seat stem hole.

STEm: Precision double Ddisc to stem connection drives

the disc without the need o

screws or pins.

SEAT: Bras bonded seatdesign lowers torque and

provides complete isolation o

lowing media rom the bod.

The seat also eatures a

molded O-ring which

eliminates the

use o fangegaskets.

SERIES 32/33 & 35/36

This valve series has man o the design eatures and

benets o the smaller Bra valves, such as high Cv ratings,

minimum parts exposed to the line media, greater

reliabilit and a proven record o long service lie.

BoDy: One piece ull fanged stle. Allbodies are drilled to be compatible

with ASME 125/150, PN 10 or other

international fange standards. Waer

stle bodies are also available.

DISc: High strength discs arefrst cast, the sealing edges arespherically machined then either

hand polished or the entire

disc is Nylon 11 coated. The

symmetrical disc proile

increases CV values, reduces

turbulence and increases

pressure recovery.

SEAT: The replaceabletongue and groove

seat to bod retention

method is the most

advanced design in the

industr. Molded O-ringeliminates the requirement

o fange gaskets. The seat

isolates the valve bod

and stem rom line media

and has been speciicall

designed to seal with slip-on or

weld-neck fanges.

BLoW-oUT PRooF STEm: A retaining ring, installedbetween the machined stem groove and gland retainer

step, provides ull retention o the stem in the unlikel

event o internal stem ailure.

ADJUSTABLE PAcKINgSySTEm:Design allows or eld adjustment o

stem packing without removing

manual operators or power

actuators. The advanced,

sel-adjusting V-Tpe stem

packing prevents external

substances rom entering

the upper stem bore.

PRImARy &

SEcoNDARy

SEALS:

These seals prevent line

media rom coming

in contact with the

stem or bod.Primary

Seal is achieved b an

intererence t o the

molded seat fat with

the disc hub. Secondary

Seal is created because

the stem diameter is greater

than the diameter o the seatstem hole.

STEm BEARINgS:To absorb actuator side thrust and

minimize bearing riction torque,

upper and lower heav wall sleeve

bearings are utilized.

VERTIcAL THRUST BEARINg: A bronze

vertical thrust bearing eliminates disc displacement

due to the weight o the stem and disc.

Competitor Strip Seats expose the bod, stem and disc

stem hole to the line media, thus causing premature

ailure due to corrosion. Material costs are signicantl

increased or highl corrosive applications.

Brays Seatisolates the line media rom contacting the

bod and stem, thus increasing service lie and thereore

lowering costs over the lie o the valve.
