The Tri-Seal Valve Fire-Flex Series Butterﬂy valves contain

improvements and reﬁnements not found in any other high

performance butterﬂy valves. These features serve to insure

a long and trouble-free life as well as provide much simple

and less expensive maintenance when required.

A. DESIGN FEATURES

1. The Fire-Flex features an exclusive resilient and

metallic seating arrangement, under normal operating

temperatures, that assures bubble tight shutoff affected

by the pressure-activated resilient seat. In the event of

a ﬁre, the 304 stainless steel metal seat provides sealing

conforming to API 607 4th edition requirements without

relying on springs, system pressure, or the complete

destruction of the resilient seat. The ﬂexible graphite

packing and gaskets prevent external leakage, avoiding

the possibility of intensifying ﬁre.

2. Body Design – The Fire-Flex valve employs a rugged

one-piece body design with an integrally cast travel stop

and installation guides for ﬂange bolts. These guide holes

have sufﬁcient clearance to allow ﬂexibility for misalignment

of mating ﬂanges.

3. Shaft Design – The Fire-Flex shaft is a double offset

style with one-piece construction design through 16”

size, two-piece construction 18” and larger.

4. Gland Design – The Fire-Flex packing gland is a ﬂexible

graphite design. This design offers excellent sealing

characteristics at the temperature rating of the valve,

as well as the higher temperature that would be seen

in the event of a ﬁre.

5. Disc Design – The Fire-Flex disc is of rugged construction

with a sealing edge that is a segment of a ball. Once the disc

is forced into the seat, a bubble-tight seal is affected. Any

change of position of the disc once it is forced into the seat

will not affect performance. The result being that (within the

width of the edge) an exact stop position is not critical.

B. INSTALLATION

1. The Fire-Flex Series valves are bi-directional, and as

such can be installed for ﬂow in either direction. However,

a preferred ﬂow is indicated.

2. When installing a butterﬂy valve always be sure that the

new ﬂange gasket of the proper material for the intended

service media are used.

3. When installing ﬂange bolts, always tighten bolts in a

sequential pattern, shown in Fig. 1. Bolts should be

tightened to the appropriate torque, as speciﬁed by SAE

for the bolting material used.

FIRE-FLEX HIGH PERFORMANCE BUTTERFLY VALVE

NOTE: After bolts have been tightened, it is good practice

to recheck ﬂange bolt torques one-half to one hour after

initial tightening (particularly when stainless steel bolting

is used).

WARNING: As is the case with most valve types available

on the market today, (regardless of manufacturer), valve

stem seals may require periodic adjustment, therefore,

installations that do not allow access to the valve stem

should be avoided.

C. VALVE OPERATION

1. All Tri-Seal Valve Fire-Flex Butterﬂy Valves feature

¼ turn operation. Turning the valve handle 90 degrees

clockwise will fully close the valve, while 90 degree

counter-clockwise rotation will fully open the valve.

The valve handle also serves as a disc position indicator.

When the valve handle is parallel to the pipe the valve is

open, when perpendicular to the pipe the valve is closed.

To disengage the handle from the locking plate, simply

squeeze the bottom lever of the handle.

2. All Tri-Seal Valve Fire-Flex Butterﬂy valves are designed

to provide bubble tight performance when properly

selected in accordance with the valve’s pressure/temperature

rating, unless otherwise noted in the seat material

selection chart.

3. To provide the longest possible service life, a hand-

operated butterﬂy valve should be operated in either

its fully open or fully closed position. However, a

10 position locking plate is provided if an intermediate

operating position is desired.

4. The torques listed under “Break Away” at the end of this

instruction sheet are the normal expected breakaway

torques. These values represent the maximum force

required to begin to open the valve at speciﬁed differential

pressures. Typically, this breakaway torque is the maximum

torque requirement for the valve during a closed-to-open,

open-to-close cycle. Bear in mind that these have been

conﬁrmed by laboratory testing of each valve size while

pressurized with water to its maximum pressure rating

(certain highly viscous or abrasive services could cause

an increase in torque requirements).

D. MAINTENANCE

During its normal service life, the only maintenance that

may be required by your Tri-Seal Valve Fire-Flex butterﬂy

valve should be periodic stem seal adjustment. If leakage

at the stem is noted, simply tighten the packing plate until

leakage subsides. DO NOT OVER TIGHTEN, AS PREMATURE

WEAR COULD RESULT.

It is impractical to predict frequency of stem adjustment,

as it is inﬂuenced by such factors as frequency of cycling

and service media.

IMPORTANT: As is the case with ANY valve on the market

today, it is important that stem leaks do not go unattended.

Lack of maintenance of stem leakage could cause a

premature need to replace stem seals.

NOTE: If operating temperature of system is substantially

higher or lower than 80° F, initial stem seal adjustment may

be required to prevent leakage.

E. DISASSEMBLY

WARNING: Most standard bi-directional High Performance

butterﬂy valves on the market today, regardless of

manufacturer, can trap ﬂuid in the valve cavity when closed.

If your Tri-Seal Valve Fire-Flex butterﬂy valve has been used

to conduct a hazardous media, the following steps must be

taken prior to removal from line and disassembled:

1. Relieve line pressure.

2. Place valve in its half-open position and ﬂush the line to

remove the hazardous material from the valve cavity.

The valve can now be removed from the line.

NOTE: Always advise maintenance personnel when they

are maintaining or rebuilding a valve that has been

conducting hazardous material. Proper protective clothing

and eye protection should always be utilized.

3. To disassemble entire valve:

a. Having assured that BOTH line and valve cavity pressures

have been relieved, remove the valve from the line.

b. Place the valve in a vice or other suitable retention tool

that will adequately support the valve while it is being

disassembled.

c. Remove valve handle, gear operator or actuator.

d. To access the seats (PTFE and metal back up) remove

outer seat retainer and inner seat retainer by the appropriate

method listed below, wafer style 2 ½ - 14 only. With the

valve rotated so the shaft side of disc is on the seat retainer

side (past full open), rotate the seat retainer such that the

notches are no longer in the 12 and 6 o’clock positions. Lift

outer seat retainer to remove from valve then lift out inner

seat retainer. Any Grafoil gasket material should be removed.

Lift the backup metal seat out of the body by prying it from

its outside edge or inside lock lip.

e. Remove hex head cap screws, lock washers and

positioning plate from top mounting ﬂange.

f. Remove self-locking gland retainer hex nuts and

gland retainer.

g. Remove jam nuts, shaft retaining plate and outer gland ring.

h. Remove shaft retaining ring (2 ½ ” through 14” only)

stem packing and inner gland ring.

i. Remove hex head cap screws, lock washers, and cap on

the bottom of the valve.

j. Remove key (2 ½ ”- 8”) or pins (10”- 24”) from disc and

shaft assembly.

For key removal: grind off spot welds and punch out key.

For pin removal: All dowel pins have been drilled and tapped

to facilitate their extraction. The thread sizes are as follows:

10”-20” = ¼ - 20, 24” = 3/8-16.

k. Slide shaft from valve body, lift out disc and thrust

washers located at the top and bottom of shaft bore.

l. Care should be taken when replacing the bearings, as

they can be damaged while pressing them out.

F. REASSEMBLY

Having assured that all critical surfaces have been inspected,

cleaned and/or replaced, reassembly can begin.

1. If replacing shaft bearings, carefully press bearings into

the shaft bore of the valve body until bearings are ﬂush with

shoulder inside bore.

FIRE-FLEX HIGH PERFORMANCE BUTTERFLY VALVE

2. While holding the thrust washers against the milled spot

faces on the O.D. of the disc, insert the disc into the valve and

align the disc shaft bore with the body bore.

NOTE: Be sure that the disc is orientated such that the “T” on

the keyed disc (8” and smaller) or the dowel pin holes (10” and

larger) are located toward the side opposite of the seat retainer

and near the packing side.

3. Insert the shaft through the shaft bore and disc, ensuring

proper alignment of the key way or pinholes to the same of

the disc.

4. Press the key or dowel pins in place and stake to secure.

NOTE: Key should be tack-welded to insure proper operation.

5. Making sure disc is rotated fully CCW, lay ﬁrst Grafoil gasket

in seat counter bore, insert metal back up seat into body, making

sure back lock lip is in place. Lay second Grafoil on top of metal

seat. Place inner seat retainer into body. Lay third Grafoil gasket

on top of inner seat retainer. Insert the seat into the seat retainer

ensuring the ﬂat back of the seat is ﬂush with the top edge of

the retainer.

CAUTION: Care must be exercised to assure the seat is not

installed upside down. Install the seat retainer springs, with

seat retainer notches located at the 6 and 12 o’clock positions

insert the retaining springs as follows: insert the straight leg of

the retaining spring into the hole located at the bottom of the

groove on the OD of the retainer to the left of the notch that is

located at 12 o’clock, making sure that other end of the spring is

extending to the right. Then insert the remaining spring into the

hole located to the right of the notch located at 6 o’clock with the

opposite end extending to the left. NOTE: See enclosed drawing

for location of retaining springs.

6. With the valve still in the full CCW position and laying ﬂat

on a safe working surface, place the seat retainer, seat and seat

retainer springs into the valve body, such that the seat retainer is

locked into place. Rotate disc to the fully closed position. On lug

valves the seat retainer screw should not be tightened until the

disc is in the closed position.

7. To secure the seat retainer to the valve body use the

following procedure:

WAFER (2 ½ ”-14”) ONLY – With one side of the seat retainer

pressed into the valve body, depress seat retainer seat retaining

spring and push the seat retainer down so that it is ﬂush to .010

above the body. Rotate seat retainer until the notches are in the

6 and 12 o’clock positions locking the retaining springs in place.

LUG (and Wafer 16”-24”) – Install and tighten socket head cap

screws insuring the retainer is bottomed in body.

8. Install inner gland ring into shaft bore. Install ﬂexible graphite

stem packing.

9. Install shaft-retaining ring into groove on shaft. Slide outer

gland ring onto the shaft and place nameplate and shaft retaining

plate onto gland retaining studs. Secure with jam nuts.

10. Install gland retainer plate and secure ﬁnger tight with

self-locking retainer nuts. Tighten as required when installed

into service.

11. Install end cap with Grafoil seal onto bottom of the valve and

secure with lock washer and hex head cap screws.

12. Place positioning plate onto mounting ﬂange and secure

ﬁnger tight with lock washers and hex head cap screws. NOTE:

The overhang of the plate should be behind and to the right of

the seat retainer while looking at the retainer side of the valve.

13. With the valve in an approximate closed position, slide the

handle onto the shaft so that the bottom tang of the handle

engages the positioning plate. Secure handle to shaft by tight-

ening hex head cap screw on handle. Rotate the valve to its fully

closed position if the handle is not locked into the last notch of

the positing plate.

G. COMMON PROBLEMS encountered with high performance

butterﬂy valves (with associated corrective action options):

1. Shaft Leakage:

a. Tighten gland retainer nuts (careful not to over tighten –

just enough so leakage stops.)

b. Replace gland packing.

2. Leakage between Flange and Valve:

a. Tighten ﬂange bolts.

b. Replace ﬂange gasket.

3. Leakage through Valve Seat:

a. Clean seat and retainer groove. Replace seat.

b. Reposition seat on disc if evidence of minor damage is visible.

c. Replace disc and shaft assembly.

4. Excessive Torque:

a. Check alignment of valve actuator and adjust if side

loading is evident.

b. Replace bearings if slight galling has occurred on shaft.

c. Replace bearing and shaft if galling is excessive.
