Selezione valvola TRV
Step 1: Input the wished flow pressure drop and acceptable tolerance on Kv value
Flow (l/h) =
Dp (kPa) =
Tolerance in the Kv =
Choose the acceptable tolerance in %
between wished and real Kv value
between wished and real Kv value
Kv required = m³/h
Dp (kPa) – hydraulic valve resistance.
Flow (l/h) – Сoolant flow through the valve.
Kv – Volumetric water flow in m³/h.
Flow (l/h) – Сoolant flow through the valve.
Kv – Volumetric water flow in m³/h.
Step 2: List of valves that satisfy your requirements
| Valve shape | DN | P/N | Presetting | Kv |
| Angle | 10 | |||
| Straight | 10 | |||
| Angle | 15 | |||
| Straight | 15 | |||
| Angle | 20 | |||
| Straight | 20 |
– Angle
– Straight
– Presetting
Step 3: Flow/Dp calculation
Dp (kPa) =
| Valve shape | DN | P/N | Presetting | Kv | Flusso (l/h) |
| Angle | 10 | ||||
| Straight | 10 | ||||
| Angle | 15 | ||||
| Straight | 15 | ||||
| Angle | 20 | ||||
| Straight | 20 |
Flusso (l/h) =
| Valve shape | DN | P/N | Presetting | Kv | Dp (kPa) |
| Angle | 10 | ||||
| Straight | 10 | ||||
| Angle | 15 | ||||
| Straight | 15 | ||||
| Angle | 20 | ||||
| Straight | 20 |
