2-way zone valve AZV 442 DN15, NC 1644210

2-way zone valve is a reliable component of heating, cooling and domestic hot water systems. Designed for precise flow shut-off in central heating or air conditioning systems, the AZV 442 valve offers effective control and automation.

Construction and application

Made of brass, this valve is characterized by durability and corrosion resistance. Its construction with an NC (normally closed) actuator ensures safety – in the event of a missing control signal, the valve remains closed. This is particularly important in applications where reliable flow shut-off is a priority. The valve is used in water installations, both for potable and drinking water.

The zone valve is ideal for use with 2-point (SPST) controllers, such as thermostats, allowing automatic temperature and flow management in individual zones of the building. This allows for efficient energy use and thermal comfort. The ability to control with an SPST signal increases resistance to interference in the electrical network, which translates to stable system operation.

Key features and benefits

• Precise regulation: Switching time of 8 seconds allows for smooth and accurate control of liquid flow.
• Safety: NC actuator guarantees reliable valve closure in case of power failure or malfunction.
• Versatility: Suitable for heating, cooling and domestic hot and cold water installations.
• Efficiency: Kvs value of 11 provides adequate flow for installations with a diameter of DN15.
• Durability: Brass housing provides corrosion resistance and long device life.
• Easy integration: Compatible with various types of 2-point (SPST) controllers.

The AZV 442 valve is a solid solution for professionals and users looking for a reliable and efficient way to control flow in their installations. Its versatility makes it suitable for both new buildings and for the modernization of existing heating and air conditioning systems.
