Custom Made Double Block And Bleed Butterfly Valve Water Supply / Distribution


Double Block And Bleed 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 Block And Bleed Butterfly Valve Features:


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.

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.
