  • Textbook – Hydraulic Circuits -Identification of Components and Analysis by Joji Parambath – Sample Pages

    The textbook explores a variety of typical hydraulic circuits in multiple positions and with color graphics. The presentation of the hydraulic circuits is structured with well-thought-out chapters. Each chapter presents circuits from simple to complex levels. Relevant symbols are portrayed chapter-wise for quick understanding. Most of the symbols used are as per ISO 1219. The types of hydraulic circuits include circuits for conventional hydraulics, electro-hydraulics, closed-circuit HSTs, PLC systems, proportional/servo valve systems, and cartridge valve systems.

    The book is meant for hydraulic professionals to refresh their circuit ideas and know more about hybrid hydraulic circuits. This book is specially written for professionals who are confused with many types of complex hydraulic circuits. They can systematically learn the critical areas in simple or complex hydraulic circuits. Teachers and students may also use this book to enhance their hydraulic knowledge. The reader can build up a strong foundation for circuit ideas and may apply these ideas to a hydraulic application considering the operating and environmental conditions, the orientation of the actuators, the type of materials used, and many supplementary factors.

  • A Comparative Study of Pressure Control Valves

    A Comparative Study of Pressure Control Valves

    Pressure control valves are used in hydraulic systems for obtaining pressure-related regulation and control tasks. The control tasks include limiting the maximum operating pressure in a hydraulic system, reducing the pressure in a part of a hydraulic circuit, unloading pumps, establishing the sequence movements of actuators, counterbalancing overrunning loads, and braking hydraulic motors while running on inertia. Accordingly, PRVs manifest themselves in a variety of forms.

    Types of Pressure Control Valves

    According to their function in hydraulic circuits, pressure regulating and control valves can be categorized into many basic types. They are (1) pressure relief valves, (2) pressure reducing valves, (3) unloading valves, (4) sequence valves, (5) counterbalance valves, and (6) brake valves. The symbolic representations of these valves are given in Figure 1.
