Three-way zone lock with actuator - 2 "M IVAR.MODULO PLUS 3

Product detailed description

This three-way zone lock with actuator is commonly used in central heating systems, particularly in commercial and industrial buildings where precise temperature control is required. It is installed in systems where zoning is necessary to manage different areas or rooms independently. The device integrates with control systems to regulate the flow of heating media, ensuring efficient distribution and energy use. The actuator allows for remote or automated operation, making it suitable for larger installations where manual adjustment is impractical.

The external threads and robust materials make it suitable for use in environments with fluctuating temperatures and pressures. The device is often found in systems with multiple zones, such as in large office buildings, hotels, or industrial facilities where different areas may require different heating profiles. The actuator ensures smooth and reliable operation, even in challenging conditions.

Technical parameters

Material	nickel plated brass CW617N
Operating temperature	-40 °C
Nominal pressure	PN 40
Supply voltage	230 V
Code	I01425714
Brand	IVAR

The nominal pressure rating of PN 40 ensures the device can handle high-pressure systems, making it suitable for use in pressurised heating circuits. The operating temperature range from -40 °C to +100 °C allows for installation in both cold and warm environments. The 230 V supply voltage is standard for electrical systems in Europe, and the nickel-plated brass construction provides resistance to corrosion and wear. These parameters are essential for determining compatibility with existing systems and for proper sizing during design.

Installation and connection

The three-way zone lock with actuator is installed in the heating circuit using external threads (MMM), which must be aligned with the corresponding fittings in the system. The actuator is connected to the control system via standard electrical wiring, ensuring a secure and stable power supply. During installation, it is important to verify that the threads are clean and undamaged to prevent leaks. The actuator should be mounted in a position that allows for easy access to the electrical connections and that complies with the IP50 or IP55 rating depending on the mounting location. Common installation mistakes include incorrect thread alignment, improper sealing, and failure to check the electrical connections for continuity and insulation.

Compatibility and accessories

This three-way zone lock is compatible with standard heating systems that use nickel-plated brass components and operate at 230 V. It is typically used in conjunction with thermostats, control panels, and other automation components. For a complete installation, additional accessories such as mounting brackets, sealing rings, and electrical connectors may be required. Installers should ensure that all components are compatible with the system's pressure and temperature requirements. No related products are specified for this model.

Technical background for designers

The three-way zone lock operates by redirecting the flow of heating media between two outlets based on the control signal received by the actuator. The nickel-plated brass body (CW617N) provides durability and resistance to corrosion, making it suitable for long-term use in heating systems. The actuator rotates the valve through 180°, allowing for precise control of the flow direction. The integration into the system depends on the control logic and the type of automation used. The service life and efficiency of the device are influenced by the quality of the installation, the maintenance of the electrical connections, and the operating conditions such as temperature and pressure fluctuations.

Service and operation

Regular inspection of the electrical connections and mechanical components is recommended to ensure reliable operation. The actuator should be checked for signs of wear or damage, and the threads should be inspected for leaks. No specific service intervals are provided in the brief. During operation, the device should be monitored for any unusual noise or movement, which may indicate a fault. If the actuator fails to respond to control signals, the electrical connections should be checked for continuity and insulation. The device should be kept clean and free from debris that could interfere with its operation.

Frequently asked questions
