TRV Valve Selection
Step 1: Input the desired flow pressure drop and acceptable tolerance on Kv value
Flow (l/h) =
Dp (kPa) =
Tolerance in the Kv =
Choose the acceptable tolerance in %
between desired and real Kv value
between desired and real Kv value
Kv required = m³/h
Dp (kPa) - Valve pressure drop
Flow (l/h) - Flow rate through the valve
Kv - Flow coefficient in m³/h.
Flow (l/h) - Flow rate through the valve
Kv - Flow coefficient in m³/h.
Step 2: List of valves that meet your requirements
| Valve shape | DN | P/N Inner | P/N Outer | Presetting | Kv |
| Angle | 10 | ||||
| Straight | 10 | ||||
| Angle | 15 | ||||
| Straight | 15 | ||||
| Angle | 20 | ||||
| Straight | 20 |
*If some of the model are not suitable for your requirements, try to increase Kv tolerance
– Angle
– Straight
– Presetting
Step 3: Flow/Dp calculation
Dp (kPa) =
| Valve shape | DN | P/N Inner | P/N Outer | Presetting | Kv | Flow (l/h) |
| Angle | 10 | |||||
| Straight | 10 | |||||
| Angle | 15 | |||||
| Straight | 15 | |||||
| Angle | 20 | |||||
| Straight | 20 |
*If some of the model are not suitable for your requirements, try to increase Kv tolerance
Flow (l/h) =
| Valve shape | DN | P/N Inner | P/N Outer | Presetting | Kv | Dp (kPa) |
