About the Book
Proportional valves were developed in the mid-1980s as a low-cost alternative to servo valves. They use a proportional solenoid to position their spool at the desired position. Proportional valves are devices for obtaining infinitely variable flow and pressure controls. They can be used in the open-loop and closed-loop configurations. Trends in the valve industry today are towards the use of intelligent hydraulics. With this objective in mind, there is widespread development of proportional valves complete with transducers and electronic regulators.
This book explores the technology used in proportional valves. It also describes the construction of electrohydraulic proportional valve systems, the details of various control elements, and the characteristics of proportional valve systems. By the end of the chapters, you will have gained a deep appreciation for this incredible technology and the many ways it can be applied to obtain precise control of hydraulic systems.
The primary objective of this book is to bridge the gap between the manufacturer’s domain and the academic field by providing a comprehensive and in-depth understanding of the subject matter. The book has been designed to cater to the needs of everyone, especially those new to the field, by providing easy-to-understand information in an academic context.
