Honeywell V5825B1050
- Type: 2-way seat valve, linear characteristic
- DN + Kvs: DN 20, Kvs = 2.5 m³/h
- PN: 16 bar
- Δp range: up to 400 kPa max. close-off (actuator-dependent)
Applications
Honeywell V5825B1050 fits medium-load control points: small-to-mid section heating branch (15–40 kW), DHW primary for a small consumer count, AHU water coil at medium airflow. Paired with Honeywell Excel / Centraline controllers or legacy Excel 5000 platforms. Actuators: 3-point 24 V AC M6410 or modulating ML7420 (0–10 V). Delivery across the EU.

Flow and capacity — quick calculation
Formula: Q = Kvs × √Δp (Q — m³/h, Δp — bar).
Example: at Δp = 0.25 bar — Q = 1.25 m³/h → P ≈ 29 kW (ΔT = 20 °C). At Δp = 0.5 bar — Q ≈ 1.77 m³/h → P ≈ 41 kW. At Δp = 1.0 bar — Q = 2.5 m³/h → P ≈ 58 kW.
Designer note
V5825B uses a short 5.7 mm stroke — pair only with a matching Honeywell actuator (ML7420, ML7421, M6410). Other-brand actuators (Belimo NV24, Siemens SAS) do not fit without a specific yoke adapter. Leakage class III (0.1 % Kvs) is moderate; if tighter shutoff is required (< 0.01 %), choose V5011R with PTFE seats.
When to choose V5825B1050
- Medium-section heating branch (15–40 kW)
- DHW primary valve for low consumer count
- AHU water coil at medium airflow (1000–2500 m³/h)
- Retrofit projects on Honeywell Excel / Centraline systems
- Compatibility: Honeywell ML7420, ML7421, M6410 range. Belimo/Siemens actuators require an adapter.

FAQ
What is the V5825B stroke?
5.7 mm — a short stroke matched to Honeywell's small actuators (M6410, ML7420, ML7421). This matters when choosing actuators — other-brand units with 15 mm stroke (Danfoss AMV, Ouman M31) do not fit without an adapter.
Suitable for a potable-water DHW scheme?
The standard DZR brass body is not certified for direct potable water. In DHW schemes the valve sits on the heating (primary) side — no potable contact. For direct potable-water applications choose WRAS/DVGW-certified alternatives.
Which actuator?
Honeywell ML7420 (0–10 V modulating, 24 V AC), ML7421 (3-point, 24 V AC), M6410 (3-point), M6410C (DHW with spring-return), M6410L (heating). All match the 5.7 mm stroke.
Leakage class?
Class III per EN 60534-4 — closed-position leakage ≤ 0.1 % Kvs. Moderate class. For tighter shutoff choose V5011R (class IV).
