3-way zone valve AZV 642 DN15, Kvs=8, male thread G 3/4 inch 1664200

Zone valve – precise control in heating and air conditioning systems

This 3-way zone valve AZV 642 is a reliable element of water installations, designed for central heating or air conditioning. It serves as a switching element, allowing control of the medium flow in different circuits. Its compact design and G 3/4 inch external thread facilitate installation and integration with existing installations. This valve is particularly useful in systems where independent temperature control is required in individual zones.

AZV zone valves are characterized by SPST signal control, which means they can work with a variety of thermostats and switches – providing great flexibility in system configuration. This gives both installers and end-users convenience and full control over thermal comfort.

Construction and application – robustness and versatility

The valve body is made of durable brass, and the internal elements of PPS composite – which guarantees corrosion resistance and long-term reliability. The electric actuator is equipped with a 1-meter electrical cable and a position indicator, facilitating visual control of the valve status. The Kvs value at 8 ensures optimal medium flow while maintaining precise regulation.

The AZV 642 valve finds application in:

• Central heating systems – division into heating zones for increased comfort and energy savings.
• Air conditioning installations – independent temperature control in individual rooms.
• Underfloor heating systems – precise temperature control in each circuit.
• Industrial applications – where precise liquid flow control is required.

Key features and benefits

• Fast operation: Switching time of only 12 seconds ensures a dynamic response to temperature changes.
• Versatility: SPST signal control enables cooperation with a wide range of thermostats and switches.
• Durability: Brass body and PPS internal elements guarantee long-term reliability even in harsh operating conditions.
• Position indicator: Facilitates visual control of the valve status, simplifying the diagnosis of any problems.
• Easy installation: G 3/4 inch external thread facilitates integration with existing installations.
• Expandability: An available adapter allows expanding the permissible medium temperature range to -15÷120°C (momentarily 160°C).
• Maintenance-free: Appropriate design of internal elements minimizes the risk of the valve blocking after a long period of inactivity.
