Valves are mechanical devices that obstruct pipes or passages of liquids and gases either wholly or partially to control the flow rate as required. In our lives, we come across many valves daily but might have never noticed them.
The taps that we open and close to control the flow of water is a valve. The regulators that we use to control the flow of gas from our gas pipelines are also valves. There are gas control valves in our cookers too. Learn more about valves on DOUGLAS CHERO.
These valves are not limited to man-made things but are found naturally and that too in our bodies. Our heart has valves that help in regulating the flow of blood in our body.
Valves are either made of plastic or metal and can be controlled either by handles, levers, pedals, and wheels or can be controlled automatically.
Generally, the exterior parts are either metal or plastic and are called seat and the inner part generally has plastic and rubber valves for an effective control of the flow of fluids. Body is the inner part of the valve that fits on the seat and controls the flow by opening and closing either partially or wholly depending upon the requirement of the flow rate.
