Spare electric drive - 230V IVAR.EMV

Product detailed description

This spare electric drive is intended for use in heating systems requiring precise control of flow distribution via zone valves. Installers working in residential or commercial buildings will find it suitable for integration into central heating systems, particularly where three-way zone closures are required. The drive is typically mounted externally on valves, allowing for remote control of valve position. It is commonly used in systems with copper piping and requires careful alignment during installation to ensure proper function.

The drive operates by converting electrical input into mechanical motion, enabling the actuation of the valve. It is compatible with existing control systems that utilise 230 V power supply and can be integrated into systems with standard copper pipe connections. The installation should be performed by qualified personnel, ensuring all electrical and hydraulic connections are secure and properly insulated.

Technical parameters

Installation and connection

Installation involves securing the drive to a compatible zone valve using the provided mounting hardware. The drive connects to copper pipes with external diameters of 22 mm and 28 mm. Ensure the valve body is clean and free of debris before attaching the drive. Connect the electrical supply according to the wiring diagram provided by the manufacturer. A common mistake is incorrect alignment of the drive with the valve stem, which can lead to improper actuation. Always verify the rotation angle and time constant during commissioning to confirm correct operation.

Compatibility and accessories

This drive is specifically designed for use with the IVAR.525 EMV three-way zone closure. When replacing an existing drive, ensure the new unit is compatible with the control system in place. No additional accessories are required for basic installation, but an external MMM plug may be needed for certain configurations. Refer to the manufacturer’s documentation for full compatibility details.

Technical background for designers

The drive operates on a 230 V AC supply and converts electrical energy into rotational movement to adjust the valve position. The use of brass CW617N ensures resistance to corrosion and wear in wet environments. Integration into a larger system depends on the control logic and timing constants, which influence response speed and accuracy. The service life is affected by the frequency of operation, environmental conditions and the quality of installation. Proper insulation and protection from moisture are key to long-term reliability.

Service and operation

Periodic checks are recommended to ensure the drive remains operational. Inspect the electrical connections for signs of wear or corrosion and verify that the drive moves freely without resistance. If the drive fails to respond to control signals, disconnect the power and inspect the internal components for damage. No scheduled service intervals are specified, but early detection of issues can prevent system downtime.

Frequently asked questions

Can this drive be used with copper pipes of other diameters?
It is specifically designed for copper pipes with external diameters of 22 mm and 28 mm. Use with other sizes is not recommended without verification from the manufacturer.

Is this drive compatible with all IVAR zone valves?
It is intended for use with the IVAR.525 EMV three-way zone closure. Compatibility with other models should be confirmed through the manufacturer’s documentation.

What is the power consumption of this drive?
It consumes 7 VA of power during operation, according to the manufacturer’s specifications.

Can this drive be installed in outdoor environments?
It has an IP 40 rating, which means it is not protected against direct contact with water or dust. Installation in fully enclosed, indoor environments is recommended.
