About this task
Each application is unique and requires specific engineering data to correctly size and design a system to fulfill the appropriate requirements. Typically, you replace a valve with another valve of the same size in a correctly sized and engineered system.
To make a rough field estimate of the size of valve for an application, find the valve size that you need by locating a point on a flow chart that satisfies the following requirements. For the flowcharts, see Figure 1 to Figure 6.
Follow these steps, to determine the following values:
- Water flow that the condenser needs (Flow)
- Refrigerant head pressure rise (PRISE)
- Available water pressure (PAVAIL)
Use the information that you obtain to locate a point on one of the flowcharts that satisfies all three steps. For the flowcharts, see Figure 1 to Figure 6.
