Three-way zone valve with electric actuator, 5/4" M

Product detailed description

Three-way zone valves are essential components in central heating systems, particularly in multi-room or multi-zone configurations. They allow precise control of heat distribution by regulating the flow of hot water to individual zones. Installers working in residential, commercial and industrial buildings often use these valves to ensure even heating and energy efficiency. The IVAR.525-32 EMV model is designed for integration into systems with copper piping, where accurate temperature control and reliable operation are required.

Typical applications include underfloor heating, radiator circuits and other hydronic systems. The valve is installed between the boiler and the heating elements, with the actuator receiving signals from a thermostat or control system. The system must be sized to ensure the valve can handle the required flow rate and pressure without causing excessive pressure drop or flow restriction.

Technical parameters

Installation and connection

The valve is connected using external threads (MMM), with pipe sizes of 22 mm and 28 mm for copper piping. The installation process involves aligning the valve body with the flow direction and securing it with appropriate fittings. The actuator is mounted separately and connected via electrical wiring. It is important to verify that the actuator is correctly aligned with the valve stem and that the rotation angle is within the specified 60° range. Common installation mistakes include incorrect thread orientation, failure to check for leaks after installation, and improper alignment of the actuator.

Compatibility and accessories

This three-way zone valve is compatible with standard central heating systems using copper piping. It requires a 230 V power supply and must be connected to a control system such as a thermostat or building management system. Additional components such as temperature sensors and control panels may be required depending on the system configuration. No specific accessories are listed for this model.

Technical background for designers

The operating principle of the three-way zone valve is based on the mixing of hot and cold water to maintain the desired temperature in the heating circuit. The electric actuator controls the position of the valve stem, which adjusts the flow path. The brass CW617N body provides good thermal conductivity and resistance to corrosion, ensuring long-term reliability. The system integration requires careful consideration of flow rates, pressure drop and control signal compatibility. The service life and efficiency of the valve depend on the quality of installation, regular maintenance and the operating conditions of the system.

Service and operation

Regular inspection of the valve and actuator is recommended to ensure continued performance. Checkpoints include verifying the alignment of the actuator, checking for leaks at the connections and ensuring the valve operates smoothly. No specific service intervals are provided in the technical data. The IP 40 rating indicates that the actuator is not protected against water or dust, so it should be installed in a dry environment.
