High Temperature Butterfly Valve Specifications:
Size: DN50 - 3000
Temperature: -15℃ - 150℃
Pressure: 1.0MPa/1.6MPa
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.
