Butterfly Valve Application

 

Fresh water, sewage, sea water, air, vapor, food, medicine, oils, alkalis, salt etc.

 

Adjust tightness

Rubber sealing ring and disc can adjust tightness or softness of sealing with clamping ring, it insures 

best performance of adjusting the compression of sealing.

 

Sealing reliable

Body and disc made of ductile iron which promote the impact resistance and pressure-bearing 

capacity, sealing ring made of rubber and valve seat’s sealing surface is conical shaped, make the 

sealing capacity more reliable.

 

Excellent corrosion protection

Inside electrostatic epoxy resin power coating or vitreous enamel(upon request), outside electrostatic

 epoxy resin power coating.

 

Reliable health nature 

Epoxy resin power is up to the health standard.        

 

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.

 

FEATURES 

⊙ EPDM seated, good seal 

⊙ Low weight                    

⊙ Low flow resistance

⊙ Small operation torque

⊙ Easy to install and maintain            

⊙ Open-close 90° more smoothly

                                                                 

 APPLICABLE STANDARDS 

1.  Design according : API 609

2.  Test standard according: JIS B2003

3.  Connect flange standard according: JIS B2212

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.

 

 Delivery:

When delivery or store the butterfly valve, should keep in dry and cool environment.

 

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.

8.4. 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.
