Irrigation Solenoid Valve Buying Guide

buy irrigation solenoid valves

Do you need an irrigation solenoid valve? No problem because you can find them in many stores. But in this section there will be many different models, how do you know you are making the purchase that is really right for you? Sometimes it will depend on how you use it. And it is that these solenoid valves are not only used for irrigation, but sometimes the washing machine also has one. And other electrical appliances. That is, they have multiple uses. Therefore, if the one you are looking for is irrigation, here we give you the keys that we consider the most important.


When buying irrigation solenoid valves, you should know that there are five different types. These are:

  • Single or membrane. They are one of the most used in homes because they control water flow.
  • Assisted. They are also called hydraulic valves. In this case, the solenoid does not work as a controller for the device, but it works with a secondary valve.
  • of balloon. They are not very common and work manually.
  • of membrane. For irrigation they are the most used because the system they use is the most compatible with the programmers. In addition, you can find different types, both electric, battery-powered, WiFi…
  • Motorized. They have a programmer so they must have an engine to run them. This can be connected to electricity (electric) or batteries. Currently, you can also find it wireless, since it connects to the router’s WiFi.


As for its price, the truth is that it is not expensive. From 10 euros you can already find some models. Now, it is true that, on its own, this device will not work for you because it needs other parts for the automatic irrigation to work. In other words, it’s one more piece than it takes to build an irrigation system for plants.

How does an irrigation solenoid valve work?

As you know, and if not, we have already explained to you, the irrigation solenoid valves are related to automatic irrigation. They are a very important part since they are responsible for opening or closing the passage of water in the pipes where they are installed.

These solenoid valves have an electrical device which is the one that gives the signal to the room to open or close and this is controlled by the irrigation controller. Therefore, we could say that the irrigation solenoid valves are the parts that are in charge of letting the water pass, or cutting it off, according to the instructions given to it.

As a rule, when a solenoid valve is installed, it prevents the passage of water because it is closed. When there is a voltage, that is to say a current of a few volts, the solenoid is activated, which allows a membrane to rise, which is what allows the water to flow. In other parts it does not interact directly with the solenoid but with another secondary valve.

Is that how it works. On the downside, there is the fact that it loses a little water pressure, but in return we have an independent system and we save water and watering time.

Or buy?

Now that you know a bit more about what an irrigation solenoid valve is and how it works, the next step is to get to know some stores where you can find this item. You know where? We suggest two stores where you can find them.


The first option we offer is Amazon. Especially in the aspect that they take it to your home, with which you do not have to travel and they are also fast in shipments. But we also have the advantage of being able to find more products thanks to its openness to third-party sellers.
