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
V5825B1076 is a common pick for 60–150 kW substation primaries. When Q > 5 m³/h with a limited Δp — step up to V5825B1084 (DN 32 Kvs 10). To keep valve authority a ≥ 0.25, Δpvalve ≥ 25 % of Δpsystem.

FAQ
Which actuator fits V5825B1076?
Honeywell ML7420 (0–10 V), ML7421 (3-point), M6410 range. The 5.7 mm stroke ties the valve to Honeywell actuators without an adapter yoke.
Suitable as a DH primary valve?
Yes. PN 16 covers standard DH pressure. Higher-pressure points need flanged PN 25 alternatives.
Leakage class?
Class III per EN 60534-4 — leakage ≤ 0.1 % Kvs.
Can glycol mixtures be used?
Yes, up to 50 %. Higher concentrations increase viscosity — apply the glycol correction factor.
