What Is a Globe Valve?
A globe valve is a somewhat simplistic design but is crucial to modern plumbing and manufacturing. In use for more than 139 years, the globe valve was originally designed to help with the newly invented steam engine. The globe valve design is so efficient its remains a mainstay in pluming and industry here in the 21st century. Does this Spark an idea?

Function
-
The globe valve is used to regulate the flow of liquid in a pipeline. The most common application of the globe valve is a standard water faucet. When the wheel (handle) is turned, a disc is lowered or raised. When the disc is fully lowered, the water supply is shut off. When the disc is fully raised, the water flow is at its maximum rate.
History
-
The first patent for the globe valve was issued in February of 1870 to J.H. Davis.
-
Significance
-
The globe valve's invention coincided with the invention of the steam engine. The steam engine required better and more reliable valves to control water flow.
Features
-
The globe valve has several primary components. The wheel (handle) is connected to the stem which is in turn enclosed in a bonnet. The stem controls the movement of the disc which, when closed, fits into the seat to block water flow.
Appearance
-
Most globe valves have a spherical body with the stem and wheel extending from the top of the sphere. The shape of the body is where the globe valve gets its name.
