4、 Stem spacer which locates between upper stem and down stem. It prevents down stem move upward.

5、 Seat locator is casted together with valve body. It prevents seat from moving. Mid-plummer-block spliced pole avoids frequent shake of the stem below which may result the stem divorced from valve body. Gibbosity on valve seat can avoids the possibility of seat distorted badly and torque increased rapidly, when the valve was installed improperly; and it also can avoid seat wriggling during the valve is opened and closed, when there is impurity on the surface of the seat after the valve is used for some time .

6、 Wide mount surface can be adopted by diversity flange types. The flange-sealing surface of valve seat is the structure of broadside and orthodrome, which follows the requirement of thimble or welded flange connection, and also can be connected with many other flanges.

3、 Raised seal surface is combined with disk. Torque is much lower than former product. Life time is extended. Narrowband seal ring is combined with spherical disc organically, which make sure that torque will not increase before the disc close up; make sure that service life of valve seat prolonged by friction decreased and open-close torque reduced, to make sure that open-close torque will not change in a long time.

2、 Concatenate"O"series seal ring of the seat is enchased in the axle hole of valve body. The concatenate"O"series sealing ring will dilate out and tangent with valve body tightly and firmly when the stem insert the disc hole through it. In this way, when it leaks inside the valve, medium cannot afflux in the room between body and seat, which may result the accident of the seat locks disc or the seat blowout.

1、 Double plow groove seat can not only make sure that the body, seat and disc connect correctly, but also ensure that the seat can be changed conveniently, which is helpful to avoid distorting by installation fault.

Butterfly Valve

A type butterfly valve is suit for bolts LT type butterfly valve is suit for bolts

Butterfly Valves Series Center-line Type Butterfly Valves

Installation Instructions for Center-line Type Butterfly Valves

Cautions

1.Valve mounting position and location

2.Flange connection requirements：The standard of

pipes of wafer type flange must accord with the flange

of butterfly valves；We advise you to use special or

integral flange；Please don‘t use flat welding flange.

The users adopt the flat welding flange before getting

the supplier’s admission.

3.The disc should be in full closed position when installing

the valve, ensuring the piping flanges have enough space to

put the the valve insert among flanges. At the ends of the

rubber seat extrude face of the body as the flange sealing

gasket, which needn’t add the sealing gasket when

installing the valves

4.Inserting the bolts into the

flanges ,confirming that whether

the valve is centering with the

flanges with hand or spanner to

force the bolts, reference to the

flanges end face and the outer

circle of the valve.

1.Medium Requirements

The material of seat is EPDM, not allowed including

content with oil. If including oil, the torque should be

rapid increase.

6.It must chose the flange as

attachments when installing

in the piping.

8.Before mounting valves ,the flange bore

of two pieces of flange on the piping must

be centering; not allowed adjust to

centering by tightening the bolt.

9.The valve’s actuator already finish the installation

before ex-factory ,the buyer couldn’t adjust by

yourselves.

10.Special statement

Please read the instruction carefully before installing

Violating the above mentioned installing instruction

,causing the broken valve ,even more serious ,which

should be responsible for construction party.

7.Clean the piping to make the piping

clean without any impurities and oil stain.

2.The butterfly not allowed to

install at the corner of the piping.

3.It must keep clean in the inner body when installing

the body, not allowed to weld the flange ,lest that

burring the rubber seat and the anti-corrosive coating

4.Not allowed the valve as

ripping bar ,pry the flange

5.Not allowed installing the

valve under the condition of

opening against destroying

the disc.

5.Be cautious ,please

open slightly the valve

to full opening location,

check whether the disc

is centering, the disc and

the inner bore of flange

is collide or not.

6. When installing the valve, it requires symmetry 、

forced, but not over-forced. In case of badly distortions.

Subject to slightness.

The flow direction of medium

The smallest inner diameter of flange

should ensure opening the disc.

The largest inner diameter of flange

should ensure that both seat and flange

have enough area to contact.

Clients would find that the actual cost may include the invisible second and the third investment ,even many times

investments and the lose resulting from stop working expect buying product outright during the long time use by purchase

different brands of valves.

The actual calculating cost of using valves

Purchase cost + maintain cost during the evaluation process+the second time, third time, many more times for updating

investing =the actual cost of using the valve for long time

Evaluating Conclusion

For clients,they will choose that what kind of valve can obtain the optimum investment, the highest reliability and the

longest life to get the most of economic benefits.

You will be surprised found that the products of HAOLIFA manufacturing is different from others when you choose the

valves, only compare with other products for one times.
