Flow and capacity — quick calculation
Formula: Q = Kvs × √Δp.
Example: at Δp = 0.25 bar — Q = 2.0 m³/h → P ≈ 46 kW. At Δp = 0.5 bar — Q ≈ 2.83 m³/h → P ≈ 66 kW. At Δp = 1.0 bar — Q = 4.0 m³/h → P ≈ 93 kW (ΔT = 20 °C).
Designer note
V5825B1068 is a common pick for medium-load heating (40–90 kW at Δp = 0.5–1 bar). To keep valve authority a ≥ 0.25, Δpvalve must be ≥ 25 % of Δpsystem. The 5.7 mm stroke ties it to the Honeywell actuator family (ML7420/ML7421/M6410).
When to choose V5825B1068
- Small multi-family substation primary valve (40–90 kW)
- Section heating branch at medium flow
- AHU water coil at medium-to-higher airflow
- DHW primary valve for medium consumer count
- Compatibility: Honeywell ML7420, ML7421, M6410. Other-brand actuators require an adapter.

FAQ
How does V5825B1068 differ from V5825B1050?
Same DN 20 body, different Kvs (4.0 vs 2.5). V5825B1068 suits higher-flow points; V5825B1050 delivers better authority at lower flow.
When is it overloaded?
When Q > 3 m³/h with a limited Δp — step up to V5825B1076 (DN 25 Kvs 6.3). If more authority is required — step down to V5825B1050 (Kvs 2.5).
Which actuator?
Honeywell ML7420 (0–10 V), ML7421 (3-point), M6410 range.
Leakage class?
Class III per EN 60534-4 — leakage ≤ 0.1 % Kvs.
