Hydraulic Solenoid Valves: All Facts You Need To Know

Hydraulic Solenoid Valves are a type of actuator that opens up or closes depending on the flow of electrical current through them.

They are most commonly used in industrial applications, where they can control the movement and flow of fluids, gases and sometimes even slurries from one place to another.

Essentially, they allow you to control the direction that your fluid is moving in by using an input signal (such as an electric current) as opposed to having a simple mechanical switch at each location where fluid needs to be controlled.

What are solenoid valves?

A solenoid valve is a type of valve that uses electromagnetic force to control the flow of fluids or gases. This makes them useful in situations where you’d like to be able to turn on and off an application remotely, without having to manually operate something like an air compressor motor or fan.

Because they’re not as complicated as other types of valves (like butterfly valves), solenoid valves tend to be fairly inexpensive and easy to use.

They’re also fairly easy to install: all you need are some basic tools and some electrical components that you can easily find at your local hardware store or online—and some wiring skills!

If your Hydraulic Filters System requires a large amount of power, though, then using solenoid valves may not be for you—they don’t have as much torque output compared with other types of valves because they’re just so simple!

How do solenoid valves work?

Solenoid valves are used in many industries, including automotive, aerospace and medical. They are used to control the flow of fluids (liquid or gas) by electromagnetic means.

A solenoid valve is basically a mechanical switch that uses an electrical current to open or close a valve when a magnetic field is applied to it.

When power is off, the spring returns the plug to its original position to prevent any leakage from occurring at its seat when there’s no pressure on it (such as during maintenance).

Types of solenoid valves.

There are five types of solenoid valves, each with its own unique applications:

  • These can be used in any type of hydraulic control system. They consist of a three-way valve and two solenoids that work together to control the flow of fluid through the system.
  • When one of these is energised, it allows fluid to pass through; when both are energised, no fluid passes through.
  • Used for directional control applications, this device has an input port and an output port with a single inlet/outlet port between them. When one or more solenoids are activated, they act as directional controls by allowing or restricting flow from one point (the input) to another (the output).


Hydraulic Solenoid Valves are great for a variety of applications. They can be used in a wide range of industries, including industrial, agricultural and transportation.

The types of solenoid valves available are numerous and include pneumatic types that use air pressure to actuate them as well as electronic ones controlled by an electric signal.

These devices can be found in everything from cars to airplanes!

We hope this article has helped you understand the different types of solenoids on offer and how they work so that you feel confident when purchasing one for your next project.
