- operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they cost less than other valve designs, and are lighter weight so they need less support. The disc is positioned in the center of the pipe. A rod passes through the disc to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, so it induces a pressure drop, even when open.
A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.
There are different kinds of butterfly valves, each adapted for different pressures and different usage. The zero-offset butterfly valve, which uses the flexibility of rubber, has the lowest pressure rating. The high-performance double offset butterfly valve, used in slightly higher-pressure systems, is offset from the centre line of the disc seat and body seal (offset one), and the centre line of the bore (offset two). This creates a cam action during operation to lift the seat out of the seal resulting in less friction than is created in the zero offset design and decreases its tendency to wear. The valve best suited for high-pressure systems is the triple offset butterfly valve. In this valve the disc seat contact axis is offset, which acts to virtually eliminate sliding contact between disc and seat. In the case of triple offset valves the seat is made of metal so that it can be machined such as to achieve a bubble tight shut-off when in contact with the disc.

Thanks
Nice information
Thanks
Hari bol nice
Thanks, please share with others.
Thanks 😊
Welcome 😊
So nice of sir.
Thanks, please share with others.
No words for you. One of the best bhai. Plz support us on today automation.
Thank you, please share with others.
Your videos are milestones no required any recommendations. One who knows your knowledge he also automatic follow you.
Plz upload this type of automation related videos .
Thank you for so much appreciation, I don't know whether they are so much up to the mark, as you are saying. Yes, stay connected, we continue to post a video like this.

Plz upload a overhauling video on it.
One of the video uploaded, please see!
Sir koi damage actuator ko repair krne wali video krlo na. Plz
Ok
👍👍
Thanks, please share with us.
Thank you sir
Plz ICLX valves k bare me btaye
Ok, I will try !
What's the use of solenoid valve in actuator?
To on off
👌👌
Thanks😄
kha hm single acting and kha hm double acting actuator use krte h
Yes, I will make video on that
Please make a video on sf6 breaker opening closing elementary/drawing
Ok, sure
