PTFE seats and encapsulated discs are molded from pure virgin PTFE material

(thickness 3mm) providing optimum protection against permeation of the line media

and excellent corrosion resistance.


Figure 07. BFV-74T3 Cross-sectional

DISC: The PTFE lining disc has 3 mm minimum

thickness of pure, virgin PTFE encapsulated

over Stainless Steel.

SEAT DESIGN: The seat design reduces seating unseating

torque-and minimizes wear on the contacting

parts. Curvatures machined into the inner

seat area minimize contact forces between

the disc and seat as the disc approaches, or

opens from, the closed position. This unique

seat geometry permits lower torques and

reduces seat wear.

FLANGE LOCATING HOLES: Locating holes in the wafer version provide

quick and precise alignment during valve

installation eliminating disc interference with

adjacent pipe I.D.

BODY: 2-pc wafer design or lug style; epoxy coated.

NECK: An extended neck design in all valve sizes

allows 2” of piping insulation and provides

easy access for mounting actuators.

TOP STEM BUSHING: A top stem bushing, retained by a stainless steel

ring, is provided to absorb actuator side thrusts

and is acetal as standard or PTFE as an option.

The bushing assures the correct interaction

between the upper shaft and the lower shaft

while ensures the smooth running of the shaft.

SEAL CAPSULE(SECONDARY SEAL): This seal capsule fully isolates the valve body and

stem from the line media. The Seal Capsule is made

of a virgin PTFE enclosing the internal energizer.

The capsule fits into grooves machined in the upper

and lower disc hubs. When compressed between the

disc and seat during assembly, the capsule becomes

energized, exerting both upward and downward

pressure on disc and seat surfaces.

PRIMARY SEAL: The primary seal is achieved by an interference fit

between the extra wide disc hubs and contoured seat.

Disc spring, two sets for a group, is a state of

compressive deformation in the body. It will impose

elastic force on the press sleeve, compact the O-ring

and seat, improve axial sealing, then provided the

bearing stress for the seat and disc, to cover the

shortage of elasticity about PTFE seat.

Figure 09. Flange Faces

STEP 01CLEAN FACES!

Must make sure the pipe flange faces are clean. Any foreign material such as scars, welding slag, metal chips, etc., can damage the seat or disc and make disc blocked.


Figure 11. Disc Position

Figure 10. Flanges Distance

Figure 12. Bolts Tighten Sequence

STEP 02LEAVE ENOUGH SPACE!

Leave a space between flanges so that valve can be easily inserted or removed, and avoiding damaging the seat.

STEP 03OPEN COMPLETELY!

Place the valve between the flanges and center it, and then span the valve body with all flange bolts, but do not tighten the bolts. Carefully open the disc to the full open position, making sure the disc does not hit the pipe. Assembling the butterfly vales in closed position would deform the seat.

STEP 04TIGHTEN BOLTS EQUALLY!

Tighten bolts gradually till flanges are in contact with valve body, and must tighten equally in sequence as Figure 21.

Installation & Maintenance

Terofox butterfly valves allow installation at any angle on the pipeline.

Installation Precaution

1.The valve shall be installed in proper position to ensure convenient operation, maintenance, and

replacement

2.In case of negligence in medium flow direction in pipe line, valve design allows installation in

double way.

3.Before/OFF installation, the butterfly valve should be stored in warehouse. Proper storage prevents

the valve from moisture while stored; the disc is suggested to be kept open at an angle of 15 degree.

4.Prior to installation, the following processes should be completed:

(1)Pay extra attention to check if the valve operation condition is in line with the technical

specification and requirements.

(2)Clean the disc sealing area and body sealing thoroughly. Disc should remain closed before

cleaning.

(3)Make sure the handle is firmly connected to the flange and stem.

5.As mounting the butterfly valve on pipeline, the load for tightening connection bolts should be

uniformed.

6.After installation, the disc must be opened in the case of the in-line strength pressure test being

carried out.

7.After commissioning, the valve should be examined regularly. Suggested regular checkups:

(1)Whether the valve seat and ‘O’ sealing ring have been damaged.

(2)Check the sealing effects of the disc sealing area.

(3)After the valve was examined and assembled, no scuffing happens at the time of on-off rotation.

(4)After the valve was examined and assembled, the sealing test should be carried out as the

introduction.

(5)After each examination, detailed records should be filed for future reference.

Figure 14. Unnecessary Gaskets

Figure 13. Incorrectiy Welding

Figure 15. Flange Rating

NOTEWELDING BEFORE INSTALLED!

Do not weld flanges near by the installed butterfly valve, so that must weld the pipe before installation or remove the valve before welding. Lastly must clean carefully the welding slag to avoid damaging the seat.

NOTEDO NOT USE GASKETS!

The installation of a gasket between the flange and the sleeve results in an excessive deformation of the latter; this has the effect of preventing the closure of the disc, or block if it is already in the closed position.

NOTEDO NOT USE UNSUITABLE FLANGES!

The installation of unsuitable flanges would jam the disc or create turbulences in the pipe.


Figure 17. Without Flange in the End Figure 18. With A Flange in the End

NOTEHORIZONTAL AXIS INSTALLATION!

It would be better to install big size butterfly valve with the stem horizontally. In case of used in services with powders or muddy fluids, valve must be installed with the stem in horizontal position to allow sediments to flow easily at opening.

NOTEEND PIPING INSTALLATION !

When valve installed at the end of piping:

Normally for Dovetailseat type and Vulcanizedseat type, we caninstalling withoutend flange.

Installing with a blind flange in the end to secure tightness at max pressure ( 16 bar )and all types butterfly valves.

Vertical axis installing for general installation.

Horizontal axis installing for particular fluids or big size valves.

1. Before the maintenance, always advise the maintenance personnel that the proper eye, head and whole

body protection always be utilized.

2. Before the maintenance, always make sure the pressure is released safely by partly opening the valve.

3. Prior to the maintenance, flush the butterfly valves and the pipe lines attached and make sure that no

(dangerous) residues are left.

4. Ensure that the installation, together with pressure containing parts in depressurized and secured.

5. It is impossible to predict the frequency of the maintenance interval. The maintenance interval is dependent

upon several factors which are not foreseeable by the manufacturer.

6. Operate the valve from fully open to fully close to assure its operation. Or always check the direction mark

on the lever or gear box operation.

7. Check flange bolting for any evidence of loose and make adjustment if necessary.

8. Inspect the valve and the surrounding area for previous or existing leakage at flange faces or shaft

connections.

9. Check piping and/or wiring to actuators and related equipment for looseness and correct as needed.

The following periodic preventative maintenance practices are recommended for all center line butterfly valves.

Troubleshooting

PROBLEMS SOLUTIONS

Leakagefrom stem

Leakage from seat(internal leak)when closed

The disc doesnot move

The valve does notrespond to

input signals.(if the valve operated

by actuators.)

Hard to openthe valve

The valveflow is low.

Check whether the seats are damaged.Find if the stem O-rings are damaged.Check whether any deviation between the valve and the pipe flange.

Check whether the disc can open and close fully.Check whether the operator and the disc act synchronously.If you suspect any damage to disc or seat, disassemble the valve. Visually check disc and seat for damages, and replace them if any damage is found.

Check the air pressure supplied to the valve and the condition of the filter regulator.Check the operations of accessories such as solenoid valve and air operated valve.Disassemble the valve and check whether there are any foreign obstructions in disc and seat.Check the design temperature and actual line temperature.Remove the actuator and try to operate the actuator only.

Check the air pressure supplied to the valve.Check the voltage of the solenoid valve.Apply the correct air pressure to the actuator to see whether it works properly or leaks. (If it leaks, fasten the cylinder cover bolts.)

Disassemble the valve and check whether there are any foreign obstructions, and remove them if found.Clean and grease actuator if actuator parts are corroded.

Check whether there are any foreign obstruction in the upstream pipe.Check whether the valve operates with the maximum stroke.
