If you’ve ever had mechanical problems with a car or small motorized device, the mechanic probably referred to the solenoid valve. Unless you are a mechanic or a family member, you probably don’t know what this small but important part does, or even what it looks like. You may be wondering what a solenoid is and what it does? Here you will find everything you need to know about the solenoid.

What is a solenoid?

According to the Recycling Industry Forum, the solenoid is a valve. To be precise, it’s a gas solenoid. It is a universal component used to convert electrical impulses for opening and closing the valve. They are used to control the flow of fuel in a wide range of domestic and industrial applications. Gas solenoid valves are designed as receivers that respond to electrical impulses and convert them into mechanical movements. When the solenoid valve receives a pulse, it opens or closes. When the valve is open, gasoline/fuel flows through it. If it is closed, the fuel flow stops. The open valve allows gas to flow through the pipe or into the chamber used to run the engine.

Solenoid operation explanation

Hunker then explains that there is a coil in the electromagnet that receives the electric current. This creates a magnetic field. When current is applied, usually from a battery or other electrical source, the solenoid’s coil is energized. A plunger mechanism is mounted in the coil. The energy from the coil moves the plunger, which in turn moves the valve.

Different types of solenoid valves

Solenoid valves are classified according to their normal state. Some are normally closed, which means that the closed position is the position in which the valve is normally located. In this type of valve, the coil opens when it receives an electrical impulse or current, and when there is no energy, the coil closes the valve. For a normally open valve, the position of the solenoid valve is normally open. When the solenoid coil receives an electric current, it causes the valve to close. The valve opens when the electric current stops.

What is the coil made of?

The electromagnetic coil is an integral part of the component. This part of the electromagnet is made of a conductive metal, such as. B. Aluminum wire wrapped around a hollow form or copper wire. The wire is wrapped around the valve cap. It is the magnetic flux lines that cause the plunger to behave like an electromagnet. The plunger magnetically slides into the coil and opens the valve to allow gas to pass through.

What are magnets for?

Many domestic and industrial applications require the use of a gas solenoid. These components control the flow of gasoline in a variety of pneumatic machines that require the use of gas pressure to drive their moving parts. Some manufacturing companies use solenoid valves for equipment used in their production processes. These are the most common industrial applications.

Your home probably has heaters that are powered by electromagnets. Gas solenoid valves are typically used in gas furnaces to control the flow of fuel after the pilot light is ignited. If you have other gas appliances in your home, such as. B. a gas stove/antenna, gas clothes dryer, electromagnet is a component of these appliances that helps prevent fire or natural gas poisoning in the home. The vehicles you drive use solenoid valves to control how the gasoline or diesel gets into the vehicle’s cylinders.

Who manufactures gas solenoid valves?

Several manufacturers or brands produce gas solenoid valves. Some of them specialize in magnets for specific applications. ASCO, for example, is a brand of solenoids designed for use with motorized shutoff functions to control the flow of all fuels used in combustion systems, including gasoline, liquid propane, diesel and more. The company is one of the largest manufacturers of magnets for industrial applications such as burners, incinerators, furnaces, industrial ovens and boilers. They offer a wide range of valves and control valves in various models including manual reset, 3-way reversing valves, 2-way normally closed and normally open. ASCO valves are made of stainless steel, aluminum or brass and are designed for cold climates with functionality down to minus 40 degrees Fahrenheit.

Burkert is another company that specializes in solenoid valves for liquid and gaseous media. It is an international company that produces corrosive or neutral, liquid and gaseous media that can be used for a wide range of pressures and temperatures. The founder of this company is Christian Burkert, who was a pioneer in the development of the modern solenoid valve. Another top brand is Buschjost/IMI Norgren. The company specializes in the manufacture of solenoid valves for various media, temperatures, pressures and applications. The company offers direct acting solenoid valves, indirect acting valves and hybrids of both types with forced lift.

Final thoughts

Now you know what a magnet is and how it is used. It is an essential part of most vehicles and equipment that run on fuel, and serves as a signal to open a valve that releases fuel to power the vehicle or equipment. These parts are used for the safe and successful operation of virtually all gas appliances in the home, industrial equipment that powers large factories and manufacturing sites, and more. Lawn mowers, ATVs, motorcycles, cars, trucks and many others depend on this small but vital component for performance. So now you know what your mechanic is talking about when he tells you that the solenoids are not energized and it is time to replace them.

frequently asked questions

What happens if the fuel solenoid valve is defective?

It receives an electric current from the battery that causes the solenoid valve to open, allowing diesel fuel to flow from the tank to the engine. … If the solenoid is defective, something happens that causes the starter to have no or too little power when you turn the key.

How do I know if my fuel solenoid valve is defective?

What is the function of the fuel solenoid valve?

The solenoid valve controls the flow of gas or other liquids, while the solenoid coil is driven by an electric current that creates a magnetic field. When the coil of the fuel solenoid is energized, the plunger of the coil moves and activates the valve.
