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 actuator by operating lever, handle wheel electric actuator or pneumatic actuator.
Widely used for potable water supply and distribution, waste water treatment, electric power plant, gas
supply, warm-air system, smelting plant, ship building, textile, petroleum, chemistry, or other light
industries.
Features:
⊙ Low weight
⊙ Compact structure
⊙ Low flow resistance
⊙ Small operation torque
⊙ Easy to install and maintain
⊙ Flow pattern tend to be straight
⊙ Open-close 90° more smoothly
⊙ 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.
⊙ 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.
