Applications
Honeywell V5825B1084 is the highest-throughput threaded V5825B. Fits 150–230 kW multi-family substation primary valves, commercial-building main heating-group valves, hotel/school DHW primaries at higher load. Paired with Honeywell Excel / Centraline via ML7420 (0–10 V) or M6410 (3-point) actuator. Delivery across the EU.

Flow and capacity — quick calculation
Formula: Q = Kvs × √Δp.
Example: at Δp = 0.25 bar — Q = 5.0 m³/h → P ≈ 116 kW. At Δp = 0.5 bar — Q ≈ 7.07 m³/h → P ≈ 164 kW. At Δp = 1.0 bar — Q = 10 m³/h → P ≈ 232 kW (ΔT = 20 °C).
Designer note
V5825B1084 is the largest threaded V5825B variant. Above ~230 kW step up to a flanged DN 40+ valve (Honeywell V5011R, Siemens VVF, Belimo H6/H7). The 5.7 mm stroke ties the valve to Honeywell ML7420/ML7421/M6410 actuator series.
When to choose V5825B1084
- Higher-load (150–230 kW) multi-family substation primary valve
- Main heating-group valve in commercial buildings
- Hotel/school DHW primary valve at higher load
- Retrofit projects with Honeywell Excel / Centraline
- Compatibility: Honeywell ML7420 (0–10 V), ML7421 (3-point), M6410 range.

FAQ
When does DN 32 Kvs 10 suffice, and when do I need DN 40+?
V5825B1084 handles up to ~230 kW (Δp = 1 bar, ΔT = 20 °C). Above 230 kW — or pipe velocity above 2 m/s — step up to flanged valves.
Which actuator?
Honeywell ML7420 (0–10 V), ML7421 (3-point), M6410 (3-point). Adapter-based alternatives are not recommended — the 5.7 mm stroke is atypical for other brands.
Suitable for PN 25 systems?
No. V5825B1084 is PN 16. For > 16 bar systems use flanged PN 25 alternatives.
Leakage class?
Class III per EN 60534-4 — leakage ≤ 0.1 % Kvs.
