High Temperature Butterfly Valves Features: 

Professional design

When initiating the rotary opening movement the disc is off-seated after only a few 

degree of opening movement and there is very little wear and tear between seat ring and disc.

 

Combine fastness

Stainless steel seat ring is rolled into the valve body by applying special rolling technology 

when DN<1200.  Ultrasonic spray applies seal of valve body when DN>1400.                      

 

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.

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.
