Two-way zone valve with actuator - 1/2 "M IVAR.MODULO COMPACT 2

Product detailed description

This two-way zone valve with actuator is commonly used in residential and commercial heating systems to regulate the flow of heating media such as water or glycol mixtures. It is typically installed in systems with zoning requirements, allowing individual rooms or zones to be controlled independently. The valve is designed for use in environments where temperatures can range from -40 °C to +100 °C, making it suitable for both indoor and outdoor applications in moderate climates. Installers should ensure proper alignment with system design parameters and verify compatibility with existing control systems.

The compact design and robust construction make this valve ideal for integration into modern HVAC systems. The external metric thread allows for straightforward installation in standard pipe configurations. The actuator provides reliable on/off control, ensuring accurate regulation of flow based on thermostat signals. This makes the valve particularly useful in applications where precise temperature control is required, such as in underfloor heating or multi-room systems.

Operating temperature	-40 °C
Nominal pressure	PN 40
Supply voltage	230 V
Code	I01425530
Brand	IVAR

The valve operates within a wide temperature range, from -40 °C up to +100 °C, which is essential for installations in cold climates or systems using glycol-based fluids. The nominal pressure rating of PN 40 indicates its suitability for medium-pressure systems, such as those found in central heating circuits. The supply voltage of 230 V ensures compatibility with standard European electrical systems, and the nickel-plated brass CW617N material provides resistance to corrosion and mechanical wear, extending service life in aggressive environments.

Installation and connection

To install the valve, begin by ensuring the pipeline is depressurised and drained. The valve is connected via an external metric thread, so a matching female thread in the pipe is required. Use a sealing compound or PTFE tape to prevent leaks. Align the valve in the correct direction of flow as indicated by the manufacturer’s markings. Secure the actuator housing to the valve body using the provided fasteners and connect the electrical wiring according to the control system specifications. After installation, test the valve operation manually and verify that the actuator responds correctly to control signals. Common errors include incorrect thread orientation, misaligned actuator mounting, and improper sealing, which can lead to leakage or mechanical failure.

Compatibility and accessories

This valve is compatible with standard 230 V control systems and can be integrated with thermostats, room controllers, and building management systems. For complete system functionality, additional components such as temperature sensors, control panels, and wiring accessories may be required. Accessories such as sealing rings and mounting brackets should be selected based on the specific installation conditions and system layout.

Technical background for designers

The valve operates using a linear actuator that rotates the internal gate by 90° to open or close the flow path. The actuator is powered by a 230 V supply and consumes 4 VA of power. The nickel-plated brass CW617N body offers high strength and resistance to thermal expansion, ensuring long-term stability in fluctuating temperature conditions. The external metric thread allows for secure connection in standard pipe systems. The actuator’s torque of 8 Nm ensures sufficient force to overcome system resistance during operation. The valve integrates seamlessly into heating circuits and is suitable for use with both closed-loop and open-loop systems. The service life and efficiency of the valve depend on the quality of installation, regular maintenance, and the purity of the heating medium.

Service and operation

Routine inspection of the valve should include checking for signs of leakage, verifying the tightness of all connections, and testing the actuator’s response to control signals. Lubrication of moving parts is not required due to the sealed design of the actuator. The IP rating depends on the mounting position—IP50 for horizontal mounting and IP55 for vertical mounting. No scheduled service intervals are specified in the technical documentation, but any operational anomalies should be addressed promptly to avoid system inefficiencies.

Frequently asked questions

Can the actuator be operated with a 230 V control signal?
Yes, the actuator is designed to operate with a 230 V supply voltage and is compatible with standard control systems.

Is the valve suitable for use in outdoor heating circuits?
Yes, the valve can be used in outdoor applications provided it is mounted in a protected location and the IP rating corresponds to the installation position.

What is the maximum allowable temperature for the heating medium?
The valve is rated for operation up to +100 °C, making it suitable for most heating system applications.

Does the valve require a specific orientation during installation?
Yes, the valve must be installed in the correct direction of flow as indicated by the manufacturer’s markings to ensure proper operation.
