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.
Brief introduction:
Double eccentric end flanged resilient sealing butterfly valve is operated by the disc rotating form
0° to 90°, can be applied to cut off or regulate the flow of medium.
Vitreous enamel is available upon request.
The valve can be actuated by operating lever, handle wheel, electric actuator or pneumatic actuator.
Widely used for potable water supply and distribution, electric power plant, gas supply, warm-air system,
smelting plant, chemical industry.
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.
⊙ 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.
