Danfoss VS2 DN15 reguliavimo vožtuvas
- DN: 15 (Rp 1/2" female thread)
- Kvs: 2.5 m³/h
- PN: 25 bar
- Temperature: 2 → 150 °C
Applications
Small-load heating loops, DHW branches, small substation consumer circuits. Kvs 2.5 fits flows up to ~30 kW (ΔT 20 °C). Combined with a modulating actuator (AMV 435 or AMV 20/25) driven by ECL Comfort. Delivery across the EU.

Flow/power sizing
Flow: Q = Kvs × √Δp. Power: P = Q × ΔT × 1.163. Example: Δp = 0.3 bar → Q ≈ 1.37 m³/h; ΔT 20 °C → P ≈ 32 kW.
Notes for the designer
Size VS2 by Kvs, not by DN. Valve authority β = Δp_valve / Δp_loop must be ≥ 0.5. Oversized Kvs → poor authority → unstable control. VS2 is often paired with an AVP differential-pressure controller on the branch.
When to choose VS2 DN15 Kvs 2.5
- Small-loop flow control — up to ~30 kW per design
- Apartment metering schematics, DHW branches
- Compact threaded valve required

FAQ
Which actuator?
AMV 435 (0-10 V / 3-pt) is the standard choice. Alternative: AMV 20/25 for 3-point control.
Suitable for DHW?
Yes. VS2 handles DHW flow control up to 150 °C and PN 25 bar.
VS2 vs VM2 — differences?
VS2 — DN15-25 threaded, for smaller loops. VM2 — DN25-40, for larger flows, also threaded.
