TL;DR: Danfoss VM2 DN40 — largest threaded VM2 valve for high-load heating/cooling loops.
- DN: 40 (Rp 1 1/2")
- Kvs: 25 m³/h
- PN: 25 bar
- Temperature: up to 150 °C
Applications
Multi-unit main lines, large AHU coils, substations of commercial and industrial buildings. Kvs 25 fits flows up to ~400 kW (ΔT 20 °C, Δp 0.3 bar). Delivery across the EU.
Technical specifications
| Parameter | Value |
|---|---|
| Code | 065B2019 |
| Type | Two-way seat control valve |
| DN | 40 |
| Kvs | 25 m³/h |
| PN | 25 bar |
| Connection | Rp 1 1/2" female thread |
| Temperature | up to 150 °C |
| Media | Heating/chilled water, glycol up to 50 % |

Sizing
Q = Kvs × √Δp; P = Q × ΔT × 1.163. Example: Δp 0.3 bar → Q ≈ 13.7 m³/h; ΔT 20 °C → P ≈ 318 kW.
Notes for the designer
DN40 with Kvs 25 requires a stronger actuator (AMV 55 or AMV 85) due to larger stroke and force. AMV 435 (400 N) is not sufficient.
When to choose VM2 DN40
- Heating/ventilation flow of 200-400 kW
- Main lines in large buildings
- Retrofit projects with threaded (non-flanged) connection
B2B delivery and logistics

FAQ
Is AMV 435 sufficient?
No. DN40 needs at least AMV 55 (600 N) or AMV 85 due to longer stroke.
Can it be used in PN 16 systems?
Yes. A PN 25 valve works in lower-pressure systems — extra safety margin.
