- 🎥 The solenoid valve is one of the inseparable tools of the industry, which is used in a wide variety of applications across many industries. In this video, we will discuss how solenoid valves work. We also cover three types of solenoid valves used in industry and one of the well-known applications in which solenoid valve is most frequently used.
By watching this video, you’ll get the answer to these questions:
- What is a solenoid valve?
- What are solenoid valve types?
- How does a solenoid valve work?
- What is a direct-acting solenoid valve?
- What is an indirect-acting solenoid valve?
- What is a semi-direct acting solenoid valve?
- What are the components of a solenoid valve?
======================================================
💬 Video Summary:
- The solenoid valve is an electromechanical actuator that converts electrical energy into a linear mechanical pull/push action.
- We have three main types of solenoid valves based on the operating principle: Direct-acting, Indirect-acting, and, Semi-direct acting
- Direct-acting solenoid valve: For a normally-closed valve in the rest position, the spring pushes down the plunger to effectively block the orifice and prevent the media flow from entering the orifice.
- Indirect-Acting Solenoid Valve: Consider a normally-closed valve as an example. Two chambers are separated by a diaphragm within the valve. A pinhole in the diaphragm where the media can flow from the inlet into the upper chamber, making the pressure equal in both chambers. However, the pressurized media in the upper chamber acts across a much broader area of the diaphragm than the media in the inlet. Therefore, the downward force above the diaphragm is greater than the upward force below it. This high pressure above the diaphragm, together with the presence of the supporting spring, will keep the valve closed, and the media cannot flow. The chamber above the diaphragm is connected to the low-pressure port by a small channel (called a pilot orifice) The plunger blocks this channel in the closed position.
- Semi-direct acting solenoid valve: It combines the characteristics of a direct and indirect valve with the difference that in this type of solenoid valve, the plunger is attached directly to the diaphragm. Take a look at the normally-closed valve as an example. There are two chambers in the valve, separated by the diaphragm. A tiny hole in the diaphragm connects these chambers, causing the pressure in both to equalize. The media in the upper chamber has more contact with the diaphragm than the media in the inlet. So, the diaphragm is forced down towards the valve seat, and as a result, the valve closes.
- Finally, we focus on an industrial application in which the solenoid valve is used as an actuator to control the level of liquid in the tank.

So nice
So nice of you to watch the video 💮
Thanks for the animation. Can you explain how the upward force on diaphragm will be higher than the downward force when the pilot valve opens? It seems that the pressure will become equalized on both side of diaphragm but the spring still holds the diaphragm downward so it should never open?!
if you don't mind can you talking about 3 way solenoid valve example parker 24v solenoid
Thank you for your suggestion! That's a great topic idea, and We'd be happy to cover it in a future video. We appreciate your interest in our content and hope that you find the upcoming video informative. If you have any other questions or topics you would like us to cover, please let us know. Thanks for watching!
Very 👍 👍
Thank you! Cheers! 😍
Which software is used to sketch, animate and to make the video?
I will pass your question to our animation department so they can answer you with specific details. Meanwhile, would you mind sharing our videos with your friends and colleagues? It would really help us grow the channel and reach more people. Thanks again for your support!
👍👍
Thanks dear Hesam for your support 🙌
Do u design for others
0:35 what about proportional solenoid valves?
The purpose of this video is to explain the different types of on/off solenoid valves. The valves that you are considering have different internal structures and, therefore, different applications.
❤🎉
We really appreciate that. If you like out videos, would you mind sharing them with your friends and colleagues? It would really help us grow the channel and reach more people. Thanks again for your support!
Can someone explain to me on which situation that we require to use direct, indirect or semi-direct solenoid valve? 😅 im abit confused
Dear Siti, in this video tutorial, after we introduce each kind of solenoid valve, we indicate their features and in order to know what kind of valve to use, you should evaluate the application producer with the features introduced in this video
