3.9: Valves - Types, Kinds, and Selection

Many different types of manual valves are used in industrial applications worldwide. The following article will cover the general mechanism and function of the most typical of these valves used in steam systems, such as ball valves , butterfly valves , globe valves , gate valves , and diaphragm valves. For further details jump down to: ball valve , butterfly valve. Ball valves offer very good shut-off capabilities. This characteristic minimizes valve operation time and decreases the likelihood of leakage due to wear from the gland seal. Ball valves can be divided into two categories: reduced bore and full bore. In reduced bore valves, the valve opening is smaller than the diameter of the piping; in full bore valves, the valve opening is the same size as the diameter of the piping.

Industrial valves have been around for more than a century. As applications become more specific and complicated, valves have evolved into nine major types to suit different requirements. These 9 types cover all industrial applications and services. Valve categorization depends on several considerations. For this article, valves are categorized according to the functions. Some take only one while most have two, depending on the valve design. Ball valve is part of the quarter turn valve family.

Types of Manual Valves

There are countless types of valves for use across a variety of industries and applications. When it comes to flow control valves, valve types range from simple to sophisticated ; some valves are complex enough to adjust automatically to pressure and temperature variations. No matter their construction, flow control valves are designed to regulate the flow or pressure of fluids, and they typically react to signals generated by flow meters or temperature gauges. Flow control valves can serve a number of different functions within a hydraulic flow system depending on the specific type that is used. One of the most common uses of a flow control valve is to r egulate the speed of motors or cylinders within the system.

Control valves are imperative elements in any system where fluid flow must be monitored and manipulated. Selection of the proper valve involves a thorough knowledge of the process for which it will be used. Involved in selecting the proper valve is not only which type of valve to use, but the material of which it is made and the size it must be to perform its designated task. A complete control valve is made of the valve itself, an actuator, and, if necessary, a valve control device. The actuator is what provides the required force to cause the closing part of the valve to move. Valve control devices keep the valves in the proper operating conditions; they can ensure appropriate position, interpret signals, and manipulate responses.

Hello reader, In this article, we will read the Definition, Classification of the valve, and their functions. A valve is a component that controls and regulates the fluid or directs the flow of a fluid by various kinds of closing, opening, or by partially cut off fluid flow. So to controls the flow and pressure of fluid within a system, we used valves. The gate valve is a regular type valve that is used in any process plant. Here flow of fluid is controlled in linear motion.

the flow rate and pressure. To select the correct valve to fulfill these functions properly, an outline of the different types of valves and their features is given below.

Different Types of Valves used in Piping – A Complete Guide of Pipe Valves

In the coming years, the demand for industrial valves is anticipated to rise as they are used in various commercial construction projects, automation projects and so on. Increased industrialization, expansion of existing facilities have spurred the demand owing to technological innovations and boost the industry growth. Industrial Valves Insights:.

Learn more. At their most basic, valves are devices that work to control, regulate or direct flow within a system or process. How a valve opens and closes will not only impact the overall performance but also determine how much control you have over the flow and how quickly the valve can operate. On top of the mechanical motion involved with a valve, also consider the method of actuation. In most cases, valves fall into one of three categories:.

Different types of valves are used in piping. In this article, I have covered classifications of valves and functions of valves. A valve is a device that regulates, controls, or directs the flow of a fluid by opening, closing, or partially obstructing fluid flow. A sound bit complicated? Ok, let me further simplified this.
