Selecting the proper valve pipe size is important to ensure proper system operation and fluid control. In this article, DELCO Valve will share the method of selecting the appropriate valve pipe diameter.
1. Determine The System Flow Demand
Before selecting a valve size, it is important to first understand the flow data. Know the maximum, minimum and average flow rate of the system. If flow curves are available, they can be referenced to determine the range of flow rate variations.
2. Calculate The Pipe Flow Rate
Fluid flow rate is also an important factor that must be considered when selecting the valve diameter. If the flow rate is too high, it may result in energy loss, increased noise and increased valve wear. Conversely, a flow rate that is too low may result in fluid blockage and decreased system efficiency.
Should be based on the type of fluid to select the appropriate flow rate range: water: 1.5-3 m / s; gas: 15-30 m / s; steam: 20-40 m / s
3. Determine The Size of The Valve
The valve pipe diameter should be the same as the inner diameter of the connecting pipe to ensure smooth fluid flow. Calculate the required valve size according to the flow coefficient of the valve.
4. Consider Pressure Drop
Allowable pressure drop: Determine the maximum allowable pressure drop according to system requirements.
Calculation of pressure drop: use the pressure drop formula or valve selection software to calculate the pressure drop of different pipe diameters, select the pipe diameter to meet the system requirements.
5. Consider The Fluid Characteristics
Liquid, gas or steam flow characteristics are different, you need to choose the appropriate valve size. High viscosity or high density fluid may require a larger pipe diameter to reduce resistance.
6. Refer To Manufacturer's Recommendations
Check the technical manual or selection guide provided by the valve manufacturer. Talk to the valve supplier or engineer for professional advice.
7. Practical Application Scenarios
High pressure systems may require stronger valves and larger pipe diameters. Consider the space constraints of the site installation and select the appropriate pipe diameter and valve type.
8. Consider Future Expansion and Change
If it is anticipated that the system will need to increase flow or add additional branch piping, select a pipe diameter with sufficient margin. This will provide flexibility for future development of the system and reduce subsequent changes and costs.
Summary
Selecting a valve size requires consideration of flow rate, velocity, pressure drop, fluid properties and system requirements. By making reasonable calculations and referring to the manufacturer’s recommendations, you can ensure that the most appropriate valve size is selected to optimize system performance.
