Popular Valves Being Used Today
A valve is a mechanical device which is used to regulate the flow of liquids or gases in pipes so the substances can flow in accordance with a specific use or need. There are many types of valves that are available today as they are designed for various applications.
The following types of valves are the usual valves that are being used today:
* Gate Valve
By its name, a gate valve acts like a gate that allows flow of liquid when it is opened and dis-allows flow when it is closed. It is commonly known as a stopper valve placed with pipeline. It uses a wedge that slides in and out to prevent the flow of liquid or other substances.
* Globe Valve
Named for its spherical shape, a globe valve is placed on a portion of the piping system where there is a division which can be closed or opened by a movable plug. The plug is operated by a screw connected through a stem. Typically, globe valves are automated using sliding stems although manually operated globe valves are used which can be turned using a handwheel.
