Best Answer

A 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 do you mean by solenoid valve and its application?

In many ways a solenoid valve is like a regular valve. It opens and closes to let the fluid or gas get through the pipe. The difference is that a solenoid does the work. A solenoid is an electrical device with a coil of wire surrounding a plunger. When electricity flows through the coil, the plunger moves up or down, due to the electromagnetic field.

What is the difference between solenoid valve and control valve?

I believe that servo is motorized and solenoid is magnetically activated.


What is a pneumatic solenoid operated spool valve?

spool valveA spool valve is a multidirectional hydraulic or pneumatic valve usually operated by a joystick. It has several hoses attached to it leading to different pneumatic rams. When the joystick is pushed in one direction, it causes the valve to shut off one of the pneumatic hoses leading to the ram and open the other. Which way the joystick is pushed moves the piston in the ram in or out. Since you specified a solenoid operated valve it is operated not by a joystick that is directly connected to the valve but rather an electric joystick like the you would use in a video game and an electrical signal is sent to activate a solenoid that does the same thing but can be much farther away from the operator. Solenoid Actuated Pneumatic Spool ValveA solenoid actuated pneumatic spool valve is a spool valve actuated by an electric solenoid. They are often used in industrial automation and are usually controlled by a PC or a PLC (Programmable Logic Controller) rather than a manual switch. To reduce the size and power consumption of the solenoid, often the solenoid does not directly actuate the spool. Instead, the solenoid actuates a small internal valve which directs upstream air pressure to move the spool. This is called an air piloted solenoid actuated pneumatic spool valve. The air pilot mechanism typically requires about 40 PSI to operate reliably. If the air pressure upstream of the valve is going to be less than 40 PSI, the valve must be externally piloted, meaning that the pilot is connected to a separate air source which is above 40 PSI.


Who invented the solenoid valve?

The solenoid was invented by Andre-Marie Ampere (1775-1836).

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.

Does a 99 Mitsubishi diamante have an egr solenoid or just the egr valve. If it does have the solenoid where is it related to the valve?

Yes, the Diamante has an EGR solenoid. On any Mitsubishi, if the car has an egr valve, it has a solenoid to operate the valve. Just follow the vacuum line from the valve and it will go to the solenoid. There may be another one way valve between the valve and the solenoid, though. The solenoid is electronic.
