All That You Need To Know About Valves

Posted by daekyungcorporation on October 29th, 2013

The world of engineering is amazing. Behind the making of mighty machines, there are many small parts involved which may seem like very tiny but their importance is paramount. Each and every component has its own significance. One component that is used in many machines is valve. So, read on to find out some interesting things about valves, brought to you by DaeKyung-the leading ball valve manufacturer.

What is a valve?

A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically valves fittings, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure.

Types of valves?

Although many different types of valves are used to control the flow of fluids, the basic valve types can be divided into two general groups: stop valves and check valves.

Stop valves

A stop valve is a valve that can be closed or opened at will, as by hand, for preventing or regulating flow, as of a liquid in a pipe; - in distinction from a valve which is operated by the action of the fluid it restrains. They are of following types:

•Gate stop valve

•Globe stop valve

•Ball stop valve

Uses:

The stop valves completely stop flow of any kind through the system, often to avert a crisis before it can get out of hand. As a result, these valves are generally close to important machinery or a human workstation. There are mostly used in:

•Optional attachments of excavators.(breakers and crushers)

•Can be used in multi channels at once

•Industrial processes

Check valves

A Hydraulic Check valve is normally used in piping systems to decrease the flow reversal and allow the material, which may be gas or liquid, to flow freely in just one direction. These devices are automatically activated when liquid flows in the pipeline. They can also be installed in some systems that tend to overheat or get contaminated as a result of reverse flows; these contraptions are then used to prevent such occurrences. They are of the following types:

•Swing check

•Double check

•Ball type

•Diaphragm

•Clapper

Uses:

•Check valves are often used with some types of pumps.

•Check valves are used in many fluid systems such as those in chemical and power plants, and in many other industrial processes.

•Some types of irrigation sprinklers and drip irrigation emitters have small check valves built into them to keep the lines from draining when the system is shut off.
