Solenoid Valves
3-Way Solenoid Valves
Electric 3 Way Solenoid Valves are used for controlling the flow of water, air, vacuum, or other low-viscosity fluids.
How Does a 3 Way Solenoid Valve Work?
3-way solenoid valves have three ports: an inlet port, an outlet port, and a third port used as an exhaust port.
What Does the Exhaust Port Do?
A three-way solenoid valve's exhaust port is used to vent or release the pressure or fluid being controlled.
Advantages of 3-Way Electric Solenoid Valves
- Flexibility - They are able to be configured in a variety of ways to control media.
- Energy efficiency - 3 Way solenoid valves are a cost-effective choice.
- Reliability - Our brass 3-way valves are durable and long-lasting.
- Versatility - These are designed for use in a wide range of applications.
- Easy installation and maintenance - 3 Way electric solenoid valves are a convenient choice.
- Fast response time - Three-way solenoid valves can be opened and closed within milliseconds.
Example Applications of 3-Way Solenoid Valves
- HVAC Systems: used to control the flow of hot and cold water. Quickly switching between the hot and cold water supply allows these valves to precisely control temperature and energy efficiency.
- Irrigation Systems: help automate the flow of water to different areas.
- Automotive Industry: can be used to control the flow of coolant or the flow of air in an engine.
- Chemical Processing: controls the flow of different chemicals and fluids. They can easily switch between different chemical tanks or mix different chemicals in an automated and controlled manner.
Choosing a 3 Way Solenoid Valve
Factors to consider when selecting a 3-way solenoid valve for your system include flow rate, pressure, and temperature requirements.
3-Way Solenoid Valve vs. 3-Way Electric Ball Valve
| Feature | 3-Way Solenoid Valve | 3-Way Electric Ball Valve |
|---|---|---|

| Sizes Available | 1/8″, 1/4″ NPT | 1/2″, 3/4″, 1″ NPT |
| Voltage/Wiring | 12V DC, 24V DC, 110V AC | 3-wire, brass |
| Compatible Media | Water, air, vacuum, low-viscosity fluids | Water, oil, gas |
| Best For | Fast on/off switching, compact installs | Diverting flow, longer duty cycles |
Frequently Asked Questions
Every 3-way solenoid valve on this page is available in 12V DC, 24V DC, and 110V AC — confirm your system's available power supply before ordering. Sizes are offered in 1/8″ and 1/4″ NPT; match the port size to your existing pipe or fitting size, and factor in your required flow rate when deciding between the two.
What sizes and voltages do 3-way solenoid valves come in?
Our 3-way solenoid valves are available in 1/8″ and 1/4″ NPT, each offered in 12V DC, 24V DC, or 110V AC. Confirm your available power supply and port size before ordering.
How much do 3-way solenoid valves cost?
All 3-way solenoid valve models on this page are $52.71, regardless of size or voltage.
Should I choose a 3-way solenoid valve or a 3-way electric ball valve?
Choose a solenoid valve for fast on/off switching in compact installations. Choose an electric ball valve if your application needs to divert flow across longer duty cycles or requires more precise positioning. See the comparison table above, or shop 3-way electric ball valves here.
What's the difference between the inlet, outlet, and exhaust ports on a 3-way solenoid valve?
The inlet port brings media into the valve, the outlet port sends it to your system, and the exhaust port vents trapped pressure or media when the valve changes position — this third port is what distinguishes a 3-way valve from a standard 2-way solenoid valve.
