Key Formulas

The fundamental relationships for control valve sizing (cv/kv) are described by:

$Q = U \cdot A \cdot \Delta T$

Where:

• $Q$ = heat transfer rate (W)
• $U$ = overall heat transfer coefficient (W/m²·K)
• $A$ = heat transfer area (m²)
• $\Delta T$ = temperature difference (K)

Notes

• Results are approximate and should be verified for critical applications
• Input values should be within reasonable engineering ranges
