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.
