Applications
Schneider V241 DN 20 Kvs 6.3 fits medium-to-larger heating points at 60–150 kW: small multi-family substation primary valve, office / school section heating group, larger DHW primaries (30–70 apartments). Paired with Schneider Rubisafe / Rubinet controllers via M400 or M800 actuator. Delivery across the EU.

Flow and capacity — quick calculation
Formula: Q = Kvs × √Δp.
Example: at Δp = 0.25 bar — Q ≈ 3.15 m³/h → P ≈ 73 kW. At Δp = 0.5 bar — Q ≈ 4.45 m³/h → P ≈ 104 kW. At Δp = 1.0 bar — Q = 6.3 m³/h → P ≈ 146 kW (ΔT = 20 °C).
Designer note
V241 DN 20 Kvs 6.3 is a common choice for 60–150 kW substation primaries. If design Q < 3 m³/h — use a smaller Kvs (or Danfoss VS 2 DN 20 Kvs 4.0 as an alternative). If Q > 5 m³/h with a limited Δp — step up to DN 25 Kvs 10.
When to choose V241 DN 20 Kvs 6.3
- Small multi-family substation primary valve (60–150 kW)
- Office / school section heating group at medium flow
- DHW primary valve for 30–70 apartments
- Retrofit projects with Schneider Rubisafe / Rubinet
- Compatibility: Schneider M400 (heating) / M800 (DHW); controllers Rubisafe / Rubinet.

FAQ
When to step up to DN 25 Kvs 10?
When design flow > 5 m³/h and authority stays ≥ 0.25. DN 25 Kvs 10 delivers more capacity but lower authority — size it against the system pressure budget.
Which actuator?
Schneider M400 (heating) or M800 (DHW). Third-party: Belimo H, Siemens SAS/SAT.
Suitable as a DH primary valve?
Yes — PN 16 covers standard DH network pressure. Higher-pressure points (> 10 bar) require a flanged PN 25 alternative.
Leakage class?
Class IV per EN 60534-4.
