Medium-to-large flow loops: larger multi-unit substation mains, ventilation coils, combined heating/cooling branches. Kvs 16 fits flows up to ~250 kW (ΔT 20 °C, Δp 0.3 bar). Delivery across the EU.

Q = Kvs × √Δp; P = Q × ΔT × 1.163. Example: Δp 0.3 bar → Q ≈ 8.76 m³/h; ΔT 20 °C → P ≈ 204 kW.
DN32 is chosen when DN25 would cause excessive Δp across the valve and DN40 would result in insufficient authority. Higher Δp requires the stronger AMV 55 actuator.

AMV 435 for standard conditions. At Δp > 4 bar use AMV 55.
Choose DN32 when design flow > 5-6 m³/h — DN25 Kvs 10 would give excessive Δp across the valve (>0.6 bar).
