Three-Way Control Valves-Features
Three-Way Control Valves are versatile devices used to either divert a single fluid into two separate flows or mix two fluids into one. They provide precise control by adjusting the flow area between the plug and the valve seat.
1. Types and Functions
Mixing Control Valve: Combines two fluid streams into a single flow.
Diverting Control Valve: Directs one fluid stream into two separate outlets.
2. Operation
When the flow area between the plug and one valve seat increases, the flow area through the other seat decreases, allowing for accurate control over mixing or diverting processes.
3. Design Considerations
Unbalanced Plug Structure: Ideal for applications involving diverting or mixing but not suitable for high differential pressure conditions.
Temperature Sensitivity: Leakage may increase when fluids at different temperatures flow through the valve, due to differing expansion rates of the valve plug and seat. To minimize leakage, the temperature difference between the fluids should not exceed 150°C.
