4. Flow curve tending to straight line. Excellent regulation performance.
5. Long service life. Standing the test of tens of thousands opening/closing perations.
6. Bubbles-tight sealing with no leakage under the pressure test.
7. Wide selection of materials, applicable for various medium.
8. Gate valve, butterfly valve, globle valve, cock, glue pipe valve and diaphragm valve altogether, especially reaching and need show in the pipes and power lines system of valve switch state at high layer of valve switch state at high layer of building fire protection system, this butterfly valve body is all available.
Overall & Connection Dimensions
Guide to butterfly valve body Selection
butterfly valve body model prepared by seven unit, its meaning is as follows: nominal pressure code of valve with Arabic numerals, its value is 10MPa pressure value for the valve of the power plant industry, mediated quality high temperature exceeds 530 centigrade, its value is 10MPa pressure valve.
Material of Main Parts
Failures that Can Occur and Methods to Eliminate
Failure Phenomenon
Sealing Surface Leakage
Reason: 1. butterfly valve body 's ring folder with debris.
2. pneumatic steel butterfly valve 's sealed closed position consistent errors.
3. Export equipped with flange bolts are uneven force or compression.
4. The pressure test of the butterfly valve body is incorrect.
Elimination: 1. Elimination of impurities, cleaning the butterfly valve body cavity.
2. Adjust the worm gear or electric actuator, such as implementing agencies limit screw is reached the pressure reduce valve closed position is correct.
3. Check mating flange plane and bolt champing force should be evenly pressed.
4. Put pressure on the direction of the arrow.
butterfly valve body at Both Ends of the Surface Leak
Reason: 1. On both sides of gasket failure.
2. Uneven cargo pipe flange clamping force is not pressed.
Elimination: 1. Replace the gasket.
2. The compression flange bolts (evenly).
Method of Operation
1. butterfly valve body : handle out of the pipe into a parallel position, the pressure reduce valve in the open position, 90 centigrade angle, the valve in the closed position. Clockwise rotation of the handle is off the pressure reduce valves, and counterclockwise rotation of the handle to open the valve.
2. The butterfly valve body of the worm gear: accordign to the part of the valve is installed indicating device
identification, clockwise rotation of the handwheel off valve counterclockwise rotation of the handwheel to open the pressure
reduce valve.
3. Pneumatic, electric, electro-hydraulic linkage operation, in accordance with the drive manual.
Installation & Maintenance
Installation Note of the butterfly valve body
1. Prior to installation should check the butterfly valve body specifications, pressure, temperature, corrosion resistance and meet the requirements. Should check the valve's part is damaged or loose.
