1. Introduction to Industrial Valves

The industrial valve is the name given to the element in different sizes and designs that enable or block the passage of a certain fluid, alter the direction of a flow, regulate the supply, and control the speed, pressure, temperature, and flow of a fluid. Both pneumatic and hydraulic systems are widely used in different areas of the industry, and the promotion of flow regulation becomes indispensable in these situations. The construction of a valve depends on the use for which it will be designed. Fluid pressure, working conditions, and materials used are some of the variables to be taken into account. The study of valves is essential for a good understanding of their operation. It is necessary to understand the functions of the interconnected parts, and the knowledge to be developed can be of great importance in the making of a choice of commercially available valves. Industrial valves are classified into four main technical field categories: isolation, regulation, prevention, retention. Industrial valves play a crucial role in various industries, serving as vital components that allow or prevent the flow of fluids, adjust flow direction, regulate supply, and control factors like speed, pressure, temperature, and flow rate. With the widespread use of pneumatic and hydraulic systems across different sectors, the need for flow regulation has become indispensable. The design and construction of valves depend on their intended applications, considering variables such as fluid pressure, working conditions, and material selection. Studying valves is essential for gaining a comprehensive understanding of their functionality. It is imperative to grasp the interconnected functions of valve parts, as this knowledge can greatly influence the decision-making process when selecting from the wide array of commercially available valves. Industrial valves can be categorized into four primary technical field categories, namely isolation, regulation, prevention, and retention. These categories encompass the diverse roles and purposes that valves serve in industrial settings, highlighting their significance in ensuring operational efficiency and fluid control.

It is up to the preventive industrial valves to protect installations from damage or excessive pressure values. The return industrial valves are responsible for redirecting the fluid in the desired flow. The main methods used to control the flow of the fluid inside the control and direction valves are resistance variation, changing the flow area, stimulation of inertial forces, and interaction between the fluid and energy sources. There are also various types of valves for different uses. Some are normally open, others normally closed by pressure, and others operate both ways. These valves may vary the direction and speed of flow or regulate the flow passage. Since the introduction of hydraulic and pneumatic systems, interest in the study of fluid behavior has been the impetus for the development of various types of valves for different purposes.

    1. Classification of valves based on function and design

      The classification of valves based on function and design is essential for understanding their applications in industrial settings. Primarily, valves can be divided into two broad categories: control valves and shut-off valves. Control valves, such as globe and rotary valves, are designed to regulate flow rates, pressure, and temperature within a system, providing fine adjustments critical in process control. On the other hand, shut-off valves, including gate and ball valves, are utilized to completely stop or allow the flow of fluid in a pipeline. The design specifics, such as the valves material and internal components, also influence performance and longevity, making it vital for engineers to select appropriate types based on the operational environment and pressure conditions. Furthermore, understanding these classifications aids in developing effective calibration procedures, ensuring optimal functionality of the valve systems within various industrial applications (Krusa et al.)(Macewen et al.).
