Two-way zone valve with actuator - 5/4 "M IVAR.MODULO PLUS 2

Product detailed description

This two-way zone valve with actuator is commonly used in residential and commercial buildings for zoning control in central heating and sanitary systems. It enables precise flow regulation in response to thermostat signals, ensuring efficient thermal management. Installers typically work with these valves in underfloor heating, radiator circuits, and hot water distribution systems. The device integrates into larger HVAC systems, allowing for individual room or zone temperature control.

The valve is constructed using nickel-plated brass (CW617N) and features an external threaded connection, making it compatible with standard pipe fittings. Its design ensures reliable performance in environments with fluctuating temperatures and pressures. The actuator is designed for integration with control systems and is suitable for use with standard 230 V electrical supplies.

The nominal pressure rating of PN 40 indicates the valve can handle hydraulic loads typical of medium-pressure heating and plumbing systems. The operating temperature range from -40 °C to +100 °C makes it suitable for both cold and hot water circuits. The 230 V supply voltage ensures compatibility with standard European electrical systems. These parameters are essential for correct sizing and system integration, particularly in applications involving variable flow rates and temperature extremes.Installation and connection Before installation, ensure the valve is compatible with the system’s pressure and temperature conditions. The valve features external metric threads and should be connected using appropriate sealing compounds or gaskets to prevent leaks. Installers must verify the direction of flow indicated on the valve body to avoid incorrect orientation. Secure mounting is required to prevent vibration-induced wear. Common installation errors include improper sealing, incorrect alignment of the actuator, and failure to follow torque specifications when tightening connections.Compatibility and accessories This valve is designed for use with standard central heating and hot water systems. It requires integration with control systems such as thermostats and building automation controllers. Additional components such as temperature sensors, control wiring, and isolation switches may be necessary depending on the application. No specific related products are listed for this model.Technical background for designers The valve operates via a linear actuator that rotates the internal gate through a 90° angle to open or close the flow path. The nickel-plated brass body offers resistance to corrosion and mechanical wear, making it suitable for long-term use in wet environments. The actuator draws 4 VA of power and is rated for IP50 or IP55 protection depending on the mounting position. Designers should consider the valve’s torque rating and time constant when calculating system response times and ensuring compatibility with control logic. The material choice ensures durability in both cold and hot water applications.Service and operation Routine inspection of the valve should include checking for leaks, verifying the actuator’s movement, and ensuring the electrical connections remain secure. No specific service intervals are provided in the technical documentation. Any irregularities in actuator movement or flow control should be investigated promptly to prevent system inefficiencies. The IP rating provides guidance on the level of environmental protection the device offers during operation.Frequently asked questions

Can the valve operate in outdoor environments?
It depends on the mounting position, as the IP rating changes accordingly. In vertical positions, the IP55 rating provides protection against water jets, while horizontal mounting results in IP50 protection.

What is the maximum allowable pressure for continuous operation?
The valve is rated for a nominal pressure of PN 40, which corresponds to 40 bar at reference temperature conditions.

Is the actuator reversible for manual override?
Manual override functionality is not specified in the technical documentation. Refer to the manufacturer’s instructions for confirmation.

Can the valve be used in hot water circulation systems?
Yes, the operating temperature range includes up to +100 °C, making it suitable for hot water circulation applications.
