The most simple solenoid valve is like a plunger. The plunger holds the water from flowing into the rest of the piping. The plunger is also attached to metal core cylinder which is external to the piping. The core is "floating" inside a coil of wire. When electric current is applied to the coil, it induces a magnetic field inside and around the coil which causes the core to be pulled into it. The moving core, then, of course, releases the plunger and water flows. There usually is a spring on the other side of the core that, when the current is turned off, pushes the core and the plunger back to a closed position.

∙ 14y agoA solenoid valve is a type of valve that uses an electrical current to actuate or shift a spool or cartridge consisting of a solenoid coil and tube assembly.
Basically, this valve type uses an electric current to shift a pin to perform simple A/B tasks such as open/close valve spools.
The designation "solenoid" means that the valve operation is electrical not manual.
Maybe the easiest way to describe a solenoid valve is by thinking about an automatic car lock. The electric current get triggered, the pin gets pushed up and the doors are unlocked. A reverse current gets triggered, the pin gets pushed down, and the doors are locked.

What is the function of pneumatic valves?
If you are talking about a pneumatic solenoid valve the function of it is to control the air in and out flow in a pneumatic actuator.
What type of valve is a solenoid valve?
Solenoid valves are electromechanically operated valves which are controlled by an electric current, mostly used in fluidics. There are different types of solenoid valves, one or two port valves.
Where can I download specification PDF documents on solenoid valves?
This URL has downloadable PDF files on solenoid valves - http://www.pdfone.com/keyword/explosion-proof-solenoid-valves.html
Where can one find more information about plastic solenoid valves?
One can find information about plastic solenoid valves from a variety of places. Norgren, Reef Central, Danfoss, and GlobalSpec provide information about plastic solenoid valves.
Why two solenoid valves are required for on-off valve?
Some times on/off valves are to large to be actuated using one solenoid valve,but most of the on/off valves are being actuated using only one solenoid valve
What is the purpose behind solenoid valves?
Solenoid valves are used to stop, close, mix or distribute liquids. They are usually made from brass or aluminum and used in sprinklers, dishwashers or washing machines.
What is direct acting solenoid valve?
A direct acting solenoid valve is one in which the action of the solenoid alone switches the valve gate. Most solenoid valves are "piloted", which means that a relatively small solenoid valve is used to allow pressurized air to actuate the valve gate mechanism. Because the solenoid does all of the work in a direct acting valve, the solenoid must therefore be larger than that of a piloted valve in order to generate the switching force. Piloted solenoid valves have the advantage of being more compact and consuming less current than a direct acting solenoid valve. Direct acting solenoid valves are useful when switching low pressure fluids.
Devices that uses electromagnet?
Solenoid valves, magnetic contactors, motors.
What is the function of solenoid valve in the air conditioner?
solenoid valve function is to hold or handle the flow of gas or liquid pressure
From where should you purchase solenoid valve. How is www.valve-store.com?
This is good enough, if you want to purchase general solenoid valves like 2 way, 3 way , 4 way solenoid valves but for generic products you can also serch the manufecturer site as http://www.valve-store.com is a distributer.
What are solenoid valves comprised of?
The solenoid is comprised of a coil, coretube, core and enclosure. These are designed to handle the most demanding fluid control applications.
What are plastic solenoid valves used for?
Plastic solenoid valves are used for the release of steam and water. They come in low pressure releases as well. They range in many uses but are available for use to control water supply from the municipal source.
