As the working conditions of host equipment become more complex and severe, performance improvement and increased intelligence of high speed on/off valves (HSV) are inevitable trends in the development of digital hydraulic technology. The characteristics of HSVs can be regulated by control strategies, which determine the comprehensive performance of the system. This paper discusses the development of control strategies for HSVs. First, the results of research in relation to the discrete voltage and pulse control of single HSVs and the coding control of parallel HSVs are summarized. In addition, the advantages, disadvantages and application scope of different control strategies are analyzed and compared. Finally, the development trends are predicted from the performance regulation, intelligent maintenance, intelligent coding and function programmability.

“…For instance, in 1955, Druett obtained experimental curves for divergent conic-shaped orifices [12]. However, a somewhat common practice is to assume L = 0.528, corresponding to the critical pressure ratio, b, for γ = 1.4 (see, for example, [2,[13][14][15][16][17][18][19][20][21]).…”

Compressible flow models are commonly used for describing air flow through pneumatic valves. Because of the difficulties in predicting viscous losses, these models ultimately rely on experimental determination of coefficients. Different equations have been proposed for different fluid speeds, having the sonic fluid velocity as a reference mark. However, one might question whether a much simpler approach, where the fluid is considered as incompressible, would still give good results within the typical range of industrial applications. Moreover, practically all models presuppose that the valve output pressure decreases in time, as in a discharge process. This paper reviews some representative one-dimensional compressible flow models and discusses the appropriateness of using equations based solely on discharging flows. Two experimental circuits, where an air reservoir is pressurized and, subsequently, decompressed, are used for comparison between different flow models. It is shown that a simpler set of equations still produces acceptable results for practical pneumatic applications.

This study compares the energetic and functional aspects of pneumatic and traditional disintegration methods during the vinification of Negroamaro grapes to produce ready-to-drink wine, focusing on sustainability and energy efficiency in winemaking. It addresses the critical need to reducing costs and environmental impact in the wine industry through improved energy efficiency and sustainable practices. The experimental tests conducted reveal that the pneumatic system exhibits advantages in terms of energy consumption, production time, and thermal homogenization during fermentation compared to the traditional system. Results indicate that the pneumatic system requires significantly lower energy consumption and shorter operating times during fermentation and pressing phases while maintaining consistent wine quality, highlighting its potential for more efficient and sustainable winemaking practices.
