13 best electric solenoid

An electric solenoid is a type of electromechanical device that converts electrical energy into mechanical motion. It consists of a coil of wire wound around a central core, typically made of iron or another magnetic material. When an electric current is passed through the coil, it creates a magnetic field, which in turn generates a mechanical force on the core.

Solenoids are commonly used in various industrial and scientific applications, including solenoid valves, which are widely used in fluid control systems.Here's some key information about electric solenoids and their applications:

  1. Solenoid Valves: Solenoid valves are devices that control the flow of fluids, such as liquids or gases, by using a solenoid to actuate a valve mechanism. When the solenoid coil is energized, it moves the valve's internal components to open or close the valve, allowing or stopping the flow of fluid. Solenoid valves are commonly used in industries such as HVAC, automotive, agriculture, and manufacturing.

  2. Working Principle: The operation of a solenoid valve is based on the attraction of the magnetic field generated by the solenoid coil to the ferrous core or plunger inside the valve. When the coil is energized, the core is pulled or pushed, which in turn opens or closes the valve port, allowing or blocking the flow of fluid.

  3. Types of Solenoid Valves: There are various types of solenoid valves, including two-way, three-way, and four-way valves, each designed for specific applications. Two-way valves control the flow of a single fluid, while three-way and four-way valves are used for more complex fluid control tasks.

  4. Applications: Solenoid valves are used in a wide range of applications, such as controlling the flow of water in irrigation systems, regulating the flow of gases in industrial processes, and managing the flow of fluids in automotive transmissions.

  5. Advantages: Solenoid valves are known for their rapid response time, making them suitable for applications that require quick on/off switching of fluids. They are also energy-efficient since they only consume power when the coil is energized.

  6. Maintenance: Regular maintenance and inspection are essential to ensure the proper functioning of solenoid valves. This may include checking for leaks, cleaning components, and replacing worn-out parts.

In summary, electric solenoids, especially in the form of solenoid valves, play a crucial role in controlling the flow of fluids in various industrial and scientific settings. Their ability to convert electrical energy into mechanical motion makes them valuable components in many automated systems.

User questions & answers

Question: I want to remote mount this, are there threaded mounting holes in the valve
Answer: Dear Mike, this is a NPT thread 3/8". That means that the thread is tapered ( it is actually wider at the opening and slowly tapering down). All pipe threads are tapered ( even the British standard is tapered). If you use something that is not tapered chanses are it will never seal and it will leak. There are actual gauges that test the thread ( I can send you video if you like) and confirm the exact thread.
Question: I have 1/4 inch ID fuel line, so do I buy this in 1/4 in also and able to buy fittings for my fuel line
Answer: Even with low current (~ 2A) feeding this valve, when I tried to leave it on for a long time this valve got really hot. My test was about 30 minutes, and I ended up removing the valve from my design. I was hoping to use this as a redundant, fail safe valve, and tried a simple circuit to limit the current at the solenoid, but it still got hot when turned on. Too bad, because for the price this valve is well-built for intermittent operation.
Question: Could I use this on my sail boat? The tanks are in a propane locker
Answer: Of course yes. Do not worry
Question: How many amps will it take to open one of these? Want to use with power adapter
Answer: It is rated for air, so that would say it’s good for gaseous material and it’s rated for oil which is a hydrocarbon, as is propane so I assume it would work. I have had to solenoids fail in less than a month, so I returned them and opted for a little more expensive product.

User questions & answers

Question: Is this the new design with lower heat generation
Answer: I would say no. I'm no propane expert, but I believe the mechanical relief valve on a standard BBQ style propane tank is close to 300psi (call a gas shop to be sure for your application). This is rated 72psi for gases, so probably best to look for something with a higher pressure rating.
Question: Would this valve work with a 12v, 2.5 amp signal? I'm stepping down a 24v 5 amp control signal
Answer: It has an 18 watt rating so 18w ÷ 12v = ~1.5 amps. After setting my rectifier to 12 volts it drew 1.15 amps so you're probably safe between 1 and 1.5 amps
Question: Could I connect it to power permanently with a "kill switch" of sorts to shut off power/flow in case of an emergency? wanting to use for propane
Answer: sorry don't know an exact time. was only interested in opening long enough to fill a fuel tank and closing to stop fuel flow.
Question: can they be run continuoulsy or is over heating a problem? Also, normally closed means no fluid can flow through, right
Answer: I'm sure it would be. The one I ordered just burned up as soon as I turned it on. I use to have train horns and hooked them up to air and the electric valve I hooked up to regular horn steering wheel. Worked awesome

Answer: I run them on an agriculture sprayer. I have 50 rows of grapes and it takes me 2 minutes per row, so they are on for two minutes and then off for about 20 seconds while I make a turn and then back on for the next row. They do get hot, but they work. Yes normally closed is off, no flow.
Question: or 316 stainless steel
Answer: Cool thankjs for the question. The holes are 5mm and 1/2 deep. But US 10/32 screws fit also. Warning the holes are about 1/8 BELOW the surface, therefore you need a couple tiny washers for spacers to flush mount it. I remote mount it and run alcohol thru it as a "High Rpm Lean" Works great. Warning the solenoid has a .156" hole for fuel flow. You must test to see if your flow is enough. Funny Car Guy. PS We just won NHRA Atlanta
Question: What is the duty cycle of this solenoid? In other words, how long can it be open before it needs to close and cool down
Answer: Yes, you buy the fittings that are 1/4 npt and 1/4" out side diameter on the other end to fit your hose on.

Question: Will it work with 120 psi air pressure
Answer: Current draw of this is just over .5 amps.
Question: how hot should the coil get
Answer: Yes! 1/4” pipe OD is 0.540. You loose a bit when its threaded.
Question: What is the current draw of this solenoid
Answer: No. This one is for 3/8 hose. On the same page there is one for 1/4'' hose. This link should take you to the 1/4''. https://www.amazon.com/dp/B07TT6P4TB?ref_=pe_527950_33920250_dpLink&th=1

    Product features

    Product Description

    The electromagnetic valve is composed of an electromagnetic coil, an iron core, a spring, a diaphragm and a valve body. The diaphragm effectively isolates the iron core, the spring and the coil from the valve body. During operation, the electromagnetic coil is energized to generate a magnetic field, which controls the iron core to pull the diaphragm against the resistance of the spring and open or close the input and output ports.
