Main Factors in Valve Selection and Application
For valves used in industrial plants, the aforementioned elements provide ease of correct selection for the determination of options suitable for the purpose.
Some of these main elements are related to the working environment, some of them are related to the characteristics of the valve itself. Consideration of all other positive and negative factors together with system characteristics, usage limits of different types of valves, economic life and costs is the backbone of the system.
1-Functions expected from the valve
- On-off
- Throttling
- Stop backflow
- Adjustment
- Pressure safety
- Stable flow control
- or
Combining several of these functions
2- Type of valve
3- Valve size
4- End connection type of the valve
5- Body-bonnet and trim material
6- Size and design standards
7- type of operation
8- The environment in which the valve will be used (type of fluid, erosive and corrosive properties)
9- Ambient pressure and temperature
10- Other critical factors
11- Maximum acceptable pressure loss
