Valve Selection Principle A

1, the nature of the transport fluid

Forged Valve Body are used to control fluids, and fluids have a variety of properties, such as liquids, gases, vapors, slurries, suspensions, viscous fluids, etc., and some fluids also contain solid particles, dust, chemicals, etc. . Therefore, when selecting a valve, first understand the nature of the fluid, such as whether the fluid contains solid suspended matter? Is it possible to vaporize when the liquid is flowing? Where is the vaporization? Is it liquefied when the gas flows? How corrosive is the fluid? When considering the corrosiveness of a fluid, it is important to note that mixtures of several substances tend to be completely different in corrosiveness from a single composition.

2, the function of the valve

The function of the OEM Forged Valve Body should also be considered when selecting the valve. Is this valve used for shutting down or need to regulate the flow? If it is only used for cutting, it is also necessary to consider whether there is a requirement for rapid opening and closing; does the valve have to be closed tightly and must not leak at all? Each valve has its own characteristics and applications, and the right valve should be selected according to the functional requirements.

3, the size of the valve

The size of the valve is determined based on the flow rate of the fluid and the allowable pressure loss. It should generally be the same size as the process piping.`
