It’s certain that the growth of control valves is closely linked to the industrial procedure. It’s a fact that in early times, people have come up with the concept of regulating. Folks attempt to control the flow of water in rivers or rivers by using large rocks or tree trunks to obstruct the flow of water or alter water flow direction then.

And even there are a few simple original valves used for crop irrigation in Greek and Egyptian civilization. Later, Romans developed an intricate water system for crop irrigation and used plug and plunger valves to stop the reflux. Then the Industrial Revolution has suggested the development to another stage. James Watt invented the first-speed controller modification. People at the time tended to pay more attention to the law of flow.Get more details about control valves on Distributors of Valves Expansion, Butterfly Valve | Strainer.

control valves

This is a sort of self-control valve using a heavy hammer. When the pressure increases, the valve opening declines under the impact of the heavy hammer to be able to attain a stable pressure. The valve positioner was designed then. Throughout the 1950s, three-way cage and valves were completed to meet high demands.

From the 1970s, cage valves, especially the eccentric plug valves were popular in several fields in the industrial procedure. And since 1980, many different fine little control valve, control valve actuator is born aiming to reform the height and weight and flow of valves. When stepping into the 21st century, Field bus control valve was applied. And it’s certain that the requirement for the control valves will be greater in the future.
