aZV 452 2-way zone valve, DN15, G3/4", Kvs 10 m3/h, NO, normally open

aZV 452 2-way zone valve - DN15, G ¾", Kvs 10 m³/h (NO)

AZV 452 zone valve is designed for heating and cooling systems as a liquid shut-off element. In the version **DN15 (G ¾")**, with the characteristic of **normally open (NO)** and flow coefficient **Kvs = 10 m³/h**, it proves itself in smaller circuits or at points where a quick flow shut-off is required

Application

• Shutting off circuits in central heating and cooling systems
• Controlling the flow to specific consumers or zones
• Automation with controllers or thermostats (2-point signal)
• Installations where rapid responses to changes in demand are important
