Ⅰ. Applicability:
It is applicable to all flowing conditions for the Control of any
fluid.
(Please indicate the type of fluid in a purchase order.)
Ⅱ. Features:
1The sealing of valve is made of special materials, which is good
in temperature tolerance, erosion resistance and wear-resistance.
2It has a long service life. The valve remains in good condition
after it has been operated for tens of thousands times.
3The valve is small, compact, simple in structure, and easy for
disassembling.
4Its flow tends to a straight line, which provides good performance
in control.
5Its operation is light and handy because of its small torque. It
can be opened quickly even when the temperature is 90℃.
6The valve is full seal designed. Its air test shows nil leakage.
7It can be installed in any position and by any angle.
Ⅲ.Usages
It can be used in the industries, such as water supply and
drainage, petrochemical, water conservancy, hydropower, metallurgy,
gas, foods, drinks, pharmaceutics, environmental protection, paper,
ship, energy, fire fighting and etc. It can be used for the purpose
of flow control or blockage in containers and pipelines in contact
with corrosive or non-corrosive vapor, liquid, semi liquid, and
powder.
Ⅳ.Key Technical Data

Medium Temperature:-40℃~150
Strength Test: 2.4MPa
Seal Test: 1.76MPa
Ⅴ.Actuator
Manual (handle or turbo), Electric or Pneumatic Actuator is
available
Ⅵ.Instructions
1. Before installing the valve, it is to check the model, bore
size, technical parameters, etc. according to site conditions. A
careful read of product catalogue and instructions is recommended.
2. In order to install and remove butterfly valve conveniently, the
use of a connecting telescopic pipe is recommended during erection,
which is an option of supply with valve at client’s request.
Following is the length of connecting telescopic pipe for erection.
DN | 50 | 65 | 80 | 100 | 125 | 150 | 200 | 250 | 300 | 350 400 | 450 | 500 |
Erection Length | 138 | 150 | 175 | 180 | 200 | 220 | 255 | 310 | 340 | 370 | 390 | 400 |
Telescopic Range | 130~ 160 | 140~ 170 | 160~ 190 | 170~ 200 | 185~ 215 | 200- 230~ | 230~ 280 | 305~ 390 | 335~ 430 | 340~ 410 | 340~ 440 | 350~ 450 |
3. Before installation of valve, please clean the valve seal and
make sure there is no dirt and dust on it. It is more critical to
do so if a long preservation is contemplated.
4. At handling or at the beginning of erection, the valve must be
slightly opened (about 5°) and maintain in this position so as to
prevent disc and sealing face from damage.
5. After valve is installed onto a pipeline, when flange bolts are
not fully tightened, please open the valve manually up to a full
open position. Check the disc to make sure if it moves freely in
the pipeline. It is to further align the valve diameter and the
pipe center, before completely tightening the bolts.
6. In the event that working medium flows at a moderate rate and
tends to precipitation, it would be wise to have wafer butterfly
valve e
