3-way zone valve AZV 642 DN15 Kvs=8 external thread G 3/4 inch

aZV 642 3-way zone valve - DN 15, G ¾", Kvs 8 m³/h

AZV 642 zone valve is a compact solution for precise control of liquid flow in heating and cooling systems. This model has a connection **G ¾" (DN 15)** and a flow rate **Kvs 8 m³/h**, making it suitable for smaller circuits or installations with moderate flow requirements.

Application

• Control of circuits in heating zones and zones in buildings
• Flow control in central heating, floor heating, mixing systems
• Systems where a compact zone valve in small diameters is required
• Modernization of installations where space or hydraulic requirements dictate DN 15

Technical data

Advantages and special features

• Compact design ideal for small circuits
• G ¾" connection - Can be installed where space or hydraulic requirements dictate a small diameter
• Precise flow control thanks to Kvs value of 8 m³/h
• Possibility of cooperation with electric actuators or automatic control systems
• Easy integration into existing installations thanks to standard threads

Installation and operation tips

• Mount the valve in a position that provides easy access to the connections
• Select an actuator with the correct torque for DN 15
• Before starting the installation, bleed the entire circuit and check for leaks
• Avoid exceeding the permissible parameters (pressure, temperature) for a given valve version
• If using glycol, make sure that the concentration is in accordance with the manufacturer's recommendations so as not to impair the valve's performance
