Potable Water Supply / Distribution Cast Steel Butterfly Valve EN 593 Standard

Double Flange Butterfly Valve With Hand Wheel: DN50 to DN400, PN10


Butterfly Valve introduction:


Double Flange 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.


Double Flange Butterfly Valve Features:


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.
