Things To Be Kept In Mind When Buying Valves

Posted by daekyungcorporation on November 28th, 2013

Every component of a machine plays an important role in proper functioning of that machine. Valve is one such component. Valve is a component that controls the passage of fluid from one space to another. Depending on the type of system, fluids can be liquids, gases, and slurries, as well as fluidized solids. There are different types of valves like-ball valves, butterfly valves, check valves, gate valves, stop valves, globe valves etc. Each valve has its own unique use and applications. Therefore, it is important to use the correct valve to avoid fluid leakage and achieve maximum control. So, here are some important things that you need to know when buying valves.

Types of valves

1.Globe valve: Globe valves are used to regulate the flow of liquid in a pipeline. They have a spherical body, containing an internal baffle with an opening in it, into which a disc can be pushed to control the movement of the fluid.

2.Diaphragm valve: Diaphragm valves are used on shut-off and throttling service for liquids, slurries and vacuum/gas.

3.Gate valve: The gate valve consists of a plate-like obstruction that is raised and lowered into place to control the flow of hydraulic fluid.

4.Ball valve: A ball stop valve is a valve that uses a spherical obstruction to stop and start hydraulic flow. A ball valve is usually rotated 90° to open and close.

5.Butterfly valve: A butterfly valve consists of a circular disc with its pivot axis at right angles to the direction material is flowing.

6.Check valve: A hydraulic control valve that allows fluid to flow in one direction. Check valves prevent backflow.

7.Automatic Control Valves: Some valves regulate themselves using hydraulic actuators and require no external input at all, though some can be manually overridden. These automatic control valves work under pressure, like a check valve, and require no external power source.

How to choose the right valve according to your needs

1.As there is a different valve for different needs therefore, when choosing a valve the needs have to be specifically kept in mind.

2.Shoppers should consider the material or materials that the valve is constructed from. When working with corrosive liquids, individuals should determine which materials are not affected by the liquid's corrosive nature and use pipes and valves made only of those materials.

3.Individuals who prefer to lock their valves should look for styles that allow a padlock or other type of lock to be applied to prevent others from tampering with the valve.

4.Shoppers should also consider the durability of the valve itself as well as the wheel, lever, or knob that allows the valve to open and close before making a purchasing decision.
