In order to obtain the best performance from a valve, it is essential that the correct valve is selected for the required service. There are a number of different conditions and variables to consider in order to select the appropriate valve for a specific application.
When considering service conditions, the first step is to identify the type of treated support. Different Stainless steel valve (which is also known as “วาล์วสแตนเลส” in the Thai language )designs are best suitable for liquid while others are preferred for gas. If it is a liquid, it is important to determine whether or not will contain solid particles.

Another variable to consider is pressure and temperature throughout the handling system. This will not only dictate the correct type but also which material must be built of the valve.
In addition to considering the main function of the valves, it is also important to take into account additional variables that can affect the selection of basic hardware. These variables include any requirement for resistance to corrosion required, thermal shock limits, physical shock limits and potential fire risks.
Finally, it is important to look closely at what the valve is invited to do. The first wide range of valve functions is activated / off. Essentially, it is only that the goal is to start and stop the flow of transported media. The best valve designs for this include gate, stem, disc, plug, and ball valves.
In the end, the selection of the appropriate valve is primarily dictated by environmental variables, the environment being transported, the expected function and the surrounding service conditions.
