Butterfly Valve

Butterfly Valve

Versatile Flow Control Solutions

A butterfly valve is a type of quarter-turn rotational motion valve used for starting, regulating, and stopping flow. Its design allows for complete closure or opening of the valve by a 90° rotation. When fully closed, the disk of the valve completely obstructs the flow path, whereas in the fully open position, the disk aligns at a right angle to the flow of gas or liquid. When it comes to high-quality butterfly valves in Hubli, Neo Valves is the name to trust. Their precision engineering ensures seamless flow regulation for various applications.


Butterfly valves serve as versatile components in flow control systems, allowing for efficient start, stop, and regulation of fluid or gas flow. Larger butterfly valves frequently come equipped with gearboxes that facilitate valve operation through a handwheel connected to the stem via gears, although this might affect operating speed.


How Butterfly Valve Works

Butterfly valves operate by rotating a disc or "butterfly" to control the flow of liquids or gases. The valve can be fully closed by positioning the disc perpendicular to the flow path or fully open by aligning it parallel to the flow direction.
