JD7A1XP-16Q Series small caliber center-line type without pinsSpecification DN50 DN350
Simple design good interchangeability and low price.
Sealing of the stem is not distorted easily to avoid leakage of stem, and possesses features such as excellent capacity of supporting, stability, and fastness.
Less rubber dosage of valve seat results low potential affection so that the torque size can be controlled in a proper scope.
Using the two piece type stem without pin connection With simple design and compact structure, it is convenient for worker to maintain and dismantle. The disc with the function of automatic centering can be matched with the seat perfectly.
The valve seat with phenol aldehyde backset possesses features of break off preventing, stretch proofing and leak proofing as well as easy changing, etc.
The sealing surface is incorporated with the backrest so that the amount of the seat is decreased.
JD7A1XP-16Q Series big caliber center-line type without pinsSpecification DN400 DN6001.Valve disc and stem adopt diamond deformed hole connection which maintain valve lever original capacity at maximally under without increase the stem diameter of the premise.2.In order to eliminate disc displacement cause by valve disc and valve stem‘s dead load taking measures as following
With equipping with combination support sleeve to support valve effectively, the down-stem of disc is step holes structure.
It effectively eliminates friction caused by the self weight of valve disc and stem and makes up clearance,which is no thrust bearing between stem and end cap
Lines connecting rod connect up-stem with down-stem by combination support sleeve in the disc making valve disc, up-stem and down-stem as a whole.

Stem spacer which locates between upper stem and down stem. It prevents down stem move upward.
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 .
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.
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.
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.
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 Valves Series Center-line Type Butterfly ValvesInstallation 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.
