Electric Solenoid Valve: Find the Best One for Your Application

Electric Solenoid Valve 1

Do you know the production value of solenoid-operated valves in Japan? It’s amounted to 53.69 (approx.) billion Japanese yen! Isn’t that colossal? You’ll find similar stats for the electric solenoid valve in all the major industrialized countries, including the USA.

What is a solenoid valve, and why it’s so demanding? Simply, it’s some electromagnet that produces a controlled magnetic field. This solenoid valve is used everywhere the fluid flow control needs to be automated.

It’s the controller of your machine that shuts off, releases, doses, distributes, or mixes the fluid media. You’re supposed to use them in hydraulic pumps, air hammers, gas boilers, washing machines, and more.

Now that you know how handy it is let’s move on to the main point — how and which one to get? It’s a tricky job that’s made much simpler by our team of experts. Let’s see how!

Buying Guide: Selection Criteria for the Solenoid Valve

Now that you know what a solenoid valve is and how significant it is, it’s time to understand the different aspects of your application, such as the flow rate, flow factor, state on/off time, port size, etc. Once you know them well, there are a few factors to consider about the electric solenoid valve.

Consider the following selection criteria before you’re out to buy one.

Solenoid Valve TypeDecide whether your application needs a two-way (one inlet-one outlet) or a 3-way solenoid valve (two inlets – one outlet).

Housing Material – This is probably the most critical factor; you can determine the valve hosing material based on your media’s temperature and chemical properties. Brass is the first choice and is used for neutral media. You can also consider the stainless steel version and PVC. Check out more for the suitable housing material for your solenoid valve.

Seal Materials – Again, based on your media’s temperature and chemical properties, you can go with seal materials like NBR, Viton, EPDM, PTFE, etc. Viton is our personal favorite.

Voltage – You can’t forget that. The electric solenoid valves are available in both AC and DC. Both have their pros and cons; however, we prefer DC solenoids to AC.

Valve Function – You can select normally open or closed solenoid valves based on your operating period. The majority of the solenoids are generally closed. However, if the opening time of the valve is longer than the closing time goes for an open valve.

Other Specifications – You need to consider the different specifications: maximum/minimum pressure, type of operation (direct, indirect, or semi-direct), maximum/minimum temperature, response time, approvals, and degree of protection.
