A butterfly valve is a type of flow control device, typically used to regulate a fluid flowing through a section of pipe.
The valve is similar in operation to a ball valve. A flat circular plate is positioned in the center of the pipe.
The plate has a rod through it connected to an actuator on the outside of the valve. Rotating the actuator turns the
plate either parallel or perpendicular to the flow. Unlike a ball valve, the plate is always present within the flow,
therefore a pressure drop is always induced in the flow regardless of valve position.

1. BRIEF INTRODUCTION:
The butterfly valve is operated by the disc rotating form 0° to 90°, can be applied to cut off or regulate
the flow of medium.
The valve can be actuated by operating lever, handle wheel electric actuator or pneumatic actuator.
Widely used for potable water supply, waste water treatment, electric power plant, gas supply,
warm-air system, smelting plant, ship building, textile, petroleum, chemistry, or other light industries.

6. Operation:
6.1. The two pipe flange should be smooth.
6.2. Put the butterfly valve in the pipe line, fixed the orientation hole first.
7. Delivery:
When delivery or store the butterfly valve, should keep in dry and cool environment.
8. Note:
8.1. Pipe flange should same as the butterfly valve flange.
8.2. Check the valve before installed, the environment should correspond to the butterfly valve
specification.
8.3. Before open butterfly valve, checking the disc without dirt.
8.4. The disc must be shut off place when installed.
8.5. Adjusting the pipe connect before installed.
8.6. The connect flange should be parallel.
8.7. After installed, the pressure test disc should be open place.
8.8. If the butterfly can not natural open or close, please kindly check it careful, can not strike, tamp or
use extension lever.
8.9. When maintenance or operation, must check the stem, lever, gear box or actuator have correctly
connect. Otherwise the stem will be push by pipe pressure.
9. The malfunction and resolving:
malfunction |
whys |
solution |
Seal leak |
1, Some rubbish on the seal 2, Seal have been light damage |
① Clean the rubbish. ② Replacing the disc |
Stem Packing leak |
1, packing be damaged 2, packing lapse |
① Tighten the gland nut ② Change the packing |
flange leak |
1, the nut release 2, gasket lapse |
1 . Tighten the nut 2. Change the gasket |
10. Maintenance
Open the worm box cover and add some butter per two months.
Check the seal, packing and flange, if leak, please maintain ASAP.
