▶️Gate valves are linear motion valves. They are multi-turn type valves as the actuator requires numerous turns to change from the fully open to fully closed position. Linear motion valves are slower to operate than rotary motion valves, but this is beneficial in some instances because this trait helps avoid water hammer when opening the valve.
Gate valves are usually installed with in-line piping that requires very little obstruction to flow. When the gate valve is fully open, there is a very low pressure drop across the valve.
The gate valve bonnet allows easy access to the internal valve components. The internal valve components are referred to as the ‘trim’.
Gate valve discs are either of the inclined or parallel design. Three inclined disc designs are used, these are the solid, split and flexible wedge designs.
Gate valve seats are machined directly into the body, or, seat rings are used. Seat rings can be attached to the valve using a screw thread.
Gate valves utilise either a rising or non-rising stem design.
In service temperatures are between approximately -20 to 60 °C. In service pressure can be up to 16 bar. The maximum flow through the valve is between 5-20 metres per second depending upon if the flowing medium is a liquid or gas.

I know nothing about valves, and I could follow this really easily. Thank you for the informative video!
One of the best explanations available online..thank you savree team..looking forward for more detailed explanations of different valve's
Brilliant . this is so useful for people who want to understand valve better . Especially this is perfect for juniors and in some cases seniors alike !!!
Great video, it's helping me get through my architectural engineering classes!
This was masterfully explained.
depiction looks very interesting and makes the concept understandable very utterly
Nicely explained working of gate valve with the help of animation, thanks
Thanks a lot for the helpful explanation!
Very nice and detailed explanation of gate valve operation.
Love from India... helped me prepare for my momentum transfer exams
High quality content, congratulation!
Simple animation with details.
really easy to watch and very clear ! Keep up the great work
Thanks, will do!
Thank you sir
Love from India
Thanks very much,am a teacher,this will help me explain how the gate valve works
good job!
This video hepled me much for doing my practical exams👍🏾😁
Best of luck!
a very informative video clip. thanks a lot!
You are welcome!
Thanks!
Thank you very much
Beautiful
Very nice 👍
Thakyou for the course about gate valve. Please if you can simulate the grease with valves when are diffictive such as passing ,stuck, loosing and leaking.
Thank you very much
For the rising stem. When it’s fully closed is the stem flush with the handle or does some thread stick out?
Thanks for this my dishwasher has been breaking this is very helpful.
Great explanations about gate valves.. Appreciated..
it's very amazing and informative video, is it from 3d drawing? what the software to draw like that?
Hi your videos or much more interesting and the quality and content is much better can you just tell me what softwares are you using for 3d modelling
Thanks
Does the type of gate in the video flexible or solid? thank you for the explanation
I hope you will show us how the purifier works.
Can you make an another video for testing gate valve.
You are the best🇵🇰
u r the worst
We have received a tested gate valves in closed position. At site we attempted to test for leakage. Filled water via inspection hole then closed it after filling. Afterwards leakage from one side is observed. What is the reason/explanation for this.
we are factory to produce valve include gate valve, To your issue, it seems like the seal system is not good, and whether you confirm that the valve is closed completely or not ? Our valves have to do pressure test and seal test before delivery.
How to find the maximum lift distance of the gate?
Wow. Now I know. Its just fully opened or fully closed. No in between! No counting 1 turn or 2 turns hehehe
🙏🙏
Thanks for sharing this video, Gate valves are designed to be fully open or closed, and are not recommended to regulate the flow of liquid. When the valve is fully open, gate valves are full bore, meaning there is nothing to obstruct the flow because the gate and pipeline diameter have the same opening.
Is there a drill that you can use to open and closed gate?
@@savree-3d instead of using your hands for the hand wheel gate? We have over 14 gates to open for 1 tank
@@trustme3886 You'd need them actuated; either electrically or pneumatically, hydraulically would also be possible but is the least option I'd go for.
For that the gate valve must be equipped with something called a top-flange (ISO5210) on wich you mount an actuator
@@jonnydonny9270 thanks. If you have someone in sales let me know.
@@trustme3886 Please send me a PN on youtube, then I can help
@Trust Me Hydraulic actuation is one of the best ways of automating a gate valve. The handwheel and bonnet is replaced with a linear actuator that consists of a piston and cylinder. You apply hydraulic pressure to actuate. You can have a spring return to make a self closing / opening valve. Much better than electric actuation or pnneumatic, but it does depend on the application.
My company specializes in gate valve actuation and control, let me know if you want more information.
