Needle Valves- How Are They Different From Flow ControlApril 22, 2015
Getting to know about high pressure needle valvesJune 30, 2015
Valves are one of the most well-liked and widely utilized mechanical devices in industrial processes and routine lives. The water faucets and LPG stove knobs that we make use of in our daily lives are classic examples of valves. Furthermore, gas engines, compressors and pumps & vehicles are also referred to as valves.
Brief History of Valves
Around 4000 years ago, in order to control the flow of water spurting out from a pipe, Chinese people came up with the idea of using bamboo or cork. This innovation went on to be replaced by smelting technology and hydraulic equipment, where the cork was reinstated by a copper plug in Europe. Thanks to the invention of steamer, valves became an indispensable tool in the mechanical industry. Until this time, only butterfly and slide valves were used to control the flow of liquid/gas passing through them.
Later, a novel innovation took place in this field where threaded stem stop valves and trapezoidal threaded gate valves came into being. The sole purpose of inventing such advanced valves was to create something that’s much more adaptable to complex working conditions.
A valve typically consists of various sub-parts. From body, bonnet, seat, erect parts, seals and other locking parts. They not only control the flow of liquid or gas, but the pressure and direction of it as well.
Valves – Today
Primarily, valves are divided into 6 major categories:
- Cut-off valves: utilized for fluid pathway,
- Control valves: regulates fluid pressure,
- Check valves: prevents any reverse flow of liquid,
- Dividing valves: aid in the distribution of liquid flow in dual-directions ,
- Safety valves: ensure protection and safety while in process and
- Multi-purpose valves: serve multiple functions.
Each type possesses differentiated properties and has their own specifications that make them useful to be applied to a number of industrial applications. Therefore, household buyers and industrialists must make a wise decision. It’s not surprising to know that today; a number of industries are coming across escalated demand and requirement of various types of valves. Some of the industries are: nuclear industry, petrochemical industry, electronic industry and more. More and more efforts must be geared towards coming up with advanced valves that are energy efficient and automated.
