2-way zone valve AZV 453 DN20, NO 1645310

Zone valve for precise flow control

This 2-way zone valve AZV 453 is a reliable solution for controlling flow in central heating or air conditioning systems. Designed for installation as a shut-off element, it allows for effective temperature management in individual zones of the building. Thanks to SPST signal control, the valve can work with most available thermostats and switches, providing great flexibility in system configuration.

Construction and application

The valve is made of brass, which guarantees its durability and corrosion resistance. Designed for domestic and drinking water, it meets the requirements for both domestic and commercial installations. Its construction allows for installation in any position, making installation easier even in difficult conditions. 1" threaded connection ensures compatibility with most standard installations.

The valve is used in:

• Underfloor heating systems
• Radiator installations with zone division
• Air conditioning systems
• Circuits supplying individual rooms or groups of rooms

Key features and benefits

• Brass body: ensures long-lasting and trouble-free operation, corrosion resistance and high pressure.
• Fast switching time (8 seconds): allows for quick reaction to temperature changes and effective flow control. This is particularly important in dynamic systems where the temperature changes frequently.
• SPST signal control: enables easy integration with existing control systems and thermostats. Installers will appreciate the simplicity of connection and configuration.
• Normally open (NO): in the absence of a control signal, the valve is open, which ensures continuous flow of heating or cooling medium – this is a standard solution ensuring user comfort.
• 1m electric lead: facilitates connection to the control system without the need for additional extension cords.
• Kvs 11 m³/h: suitable flow rate for typical domestic and commercial installations.
• Surface protection: Raw state - prepared for painting or coating according to project requirements.
