What is a solenoid valve?

solenoid is an electromechanical device that allows an electrical device to control gas or liquid flow. The electrical device causes the current to flow through the coil located on the solenoid valve. This current flow results in a magnetic field that causes the metal control to move.

The drive is mechanically connected to the mechanical valve inside the solenoid valve. The valve then changes the condition, whether it opens or closes so that the liquid or gas can flow or be blocked by the valve. The spring is used to return the driver and the valve back to their resting state when the current is removed.

These devices come in various configurations and sizes. Solenoid valves can be normally open, usually closed or two -way valve. Normally open allows liquid or gas to flow unless the current is applied. Normally closed valve operates in the opposite way. The two -way version has three ports; One port is common, it usually OTEVarious and third is usually closed.

The factory automation often uses solenoid valves. A computer device operating an automation program of a factory automation that fills a liquid container can send a signal to the solenoid valve that opens, allowing the container to fill, then remove the signal to close the valve and stop the flow of liquid until there is another container. The groups to grasp items on the robot is often air controlled. The solenoid valve can be used to close the air pressure and a second valve can be used to open the grip. If a two -way valve is used, two separate valves are not required in this application.
