Industrial valves: incomparable efficiency controlling liquids and gases

Industrial valves are critical in hydraulics, in water supplying and in industrial and civil plants, because they regulate the flow of the material flowing in the pipes.

A shutter that opens the duct, causing the leakage of the liquid or gas, characterizes the anatomy of these valves. The shutter, then, performs a control action in start or interruption of the material flow.

A body allowing the connection to the pipes where the fluid flows constitutes the body of industrial valves, linking also to the control elements, which may be manual, electrical or magnetic. The body has a shutter inside, which monitors the fluid and that is manipulated by the control elements.

The industrial valves may be of various types.

Among the most used in the field of hydraulics, for example, we can find the ball valves - usually of two kind, the stainless steel ball valves and the carbon steel ball valves -, the butterfly valves and the globe valves.

In butterfly valves the shutter rotates around the axis of the tube, blocking the passage of the fluid; they may have a regulatory function, but if they are in the open position, allow small losses of material localized and, in case of partial closure, can create strong turbulence and vibrations. Because of it, the use of the butterfly valve is more appropriate for the interception function. Usually butterfly valves are used in water systems to shut-off the water and in the engines of spark ignition.

The ball valve is the most suitable in the interception of a flow within the hydraulic lines, allow for opening, closing and reduction. It also consists of a shutter - in this case a spherical one - and can be made of any metallic material; usually there are stainless steel balls or carbon steel balls. The opening of the valve is very fast and, consequently, the time of opening and closing is very short.

The globe valves have a regulatory function, this time connected to parameters such as the pressure or the flow rate. However, they can also be used as shutoff valves. In addition, in this case, the shutter balances the passage of matter.

In general, all industrial valves allow the monitoring of the inflowing matter ending up in the pipes and its capacity control.
