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.

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.
