This article is all about valves, and the various types of valves and fittings available. Valves are mechanical or electro-mechanical devices that are used to control the movement of liquids, gases, powders, etc. In most instances, valves rely on some form of mechanical barrier—a plate, a ball, a diaphragm, for example—that can be inserted and removed from the flow stream of the material passing by. Some valves are designed as on-off varieties, while others allow very fine control of the passage of media. Material selection plays an important role in specifying valves to ensure the compatibility of the wetted parts of the valve with the fluid or powder passing through it. Sizing is determined by the pipe or tubing diameter, flow rate, and the width between flanges for pipeline valves being installed as replacements. Aerosol Valves are used for dispensing the contents of aerosol cans.
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.
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. A valve is a mechanical device that controls the flow and pressure of fluid within a system or process. In piping following types of valves are used depending on the requirements.
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.
Valves are used to stop and regulate the flow of water, and each type of valve has its pros and cons and applications for which it is best suited. Most valves in a residential plumbing system are part of the water supply system and are used to control the flow of pressurized water from the water utility or a private well. Depending on the design of the valve, they may be best suited for simple ON-OFF control of the water flow, or they may be designed instead for adjusting the volume of the water flow. Most valves are available in different materials, including bronze, brass, and PVC plastic.
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.
Valves are mechanical devices that controls the flow and pressure within a system or process. They are essential components of a piping system that conveys liquids, gases, vapors, slurries etc.. Different types of valves are available: gate, globe, plug, ball, butterfly, check, diaphragm, pinch, pressure relief, control valves etc.
There are a number of different plumbing valves used to control the flow of water in a building. The pros and cons of each type are identified below. Ball valves are made with a rotating sphere that has a hole in it.

Common valve types include: Ball, Butterfly,Check, Diaphragm, Gate, Globe, Knife Gate, Parallel Slide, Pinch, Piston, Plug, Sluice, etc. The following types of valves are used in a variety of applications, these descriptions may provide a basic guideline in the selection of valves.
