Thank you from Philippines!

I know too little about so many things around me. Thanks for the clear explanation!

[@17osefalfanfadhil30]

Great Explanation.. keep it up sir !!!

[@rajankumartadhani3350]

I had seen all of your video you are doing great work. you explaination is good and animation is fantastic it will make more easier to understand the concept of all topic that you covered please make more video like that

Great video. Good work.

[@firdausyasini1875]

You doing very good job - it would be nice to reduce the duration of the video, please.

[@robermp81]

Thanks!

i love how you say "body"

[@ayooob13]

Interesting ! Thanks a lot

[@savree-3d]

You are welcome!

What might cause the disc to suddenly scrape particles off the seat? I have a valve that's been working for years. No change in any other parameters as I can see. And yet, recently, the valve scraped off a noticeable amount of particles.

Hi there, Do you also have a video on comparing butterfly valves with offset, double offset and triple offset? I try to find stuff but never come across videos showing what the valves do.

[@A_Braveworld]

If the indication is broken, how do you know valve is open or shut?

[@theunboundedspirit3313]

Why using gearbox increases response time?

[@savree-3d]

If you have a gear ratio of 2:1, the valve takes twice as long to actuate i.e. you turn the wheel more but movement is less. Hope that helps.

I really enjoyed the video ! Can this lug wafer butterfly be used with natural gas ? And a servomotor for regulation ?

[@savree-3d]

I visited a gas cavern once and a few pump storage stations etc. They had a lot of ball valves, but I don't remember seeing butterfly valves. If the seal can withstand the corrosive nature of the gas, then I imagine they can be used within gas systems. I would have to research it a bit though. Servomotor = yes, good for throttling.

[@seputardunia93]

what this speed this motorized valve can be setting more fast..?

Prices for BUTTERFLY valve

South African?

[@lebogangmanganye9266]

One here. I didn't know they are good for slurries? Slurries are generally abrasive and would eat the disc in the flow line.
