TL;DR: Danfoss AVTB 20 — self-acting thermostatic valve for DHW temperature control, DN20 version with higher Kvs. For medium substations.
- DN: 20 (G 1" male thread)
- Kvs: 3.4 m³/h
- Setting range: 20-60 °C
- PN: 16 bar
Applications
DHW temperature control in medium substations (small multi-unit buildings, small hotels, school shower sections). Higher Kvs than AVTB 15 — suitable for larger DHW flows without high Δp across the valve. Delivery across the EU.

Notes for the designer
DN20 is chosen when peak DHW flow exceeds ~0.3 l/s (>1.1 m³/h) — AVTB 15 (Kvs 1.9) would give excessive Δp. The sensor is threaded into the DHW outlet branch.
When to choose AVTB 20 over AVTB 15
- Medium substations with higher DHW flow
- Schools, sports halls, hotels with shower sections
- Larger pipe DN required

FAQ
Can I use it in a heating loop?
Technically yes, but AVTB targets DHW. Heating loops use electronic control (ECL Comfort + AMV actuator).
Does it work without network pressure?
No. AVTB opens/closes by sensor expansion; the system needs flow and pressure differential.
