Zone valve 230V DN20

Product detailed description

This 230V DN20 zone valve is commonly used in heating systems for zoned temperature control in residential and commercial buildings. It is typically installed in systems where individual zones require independent regulation, such as in multi-room heating setups or in larger properties with separate heating circuits. The valve operates in conjunction with thermostats and control systems to manage the flow of heating media, ensuring efficient and targeted heat distribution. Installers working on central heating systems, especially those involving underfloor heating or multi-loop radiators, will find this valve suitable for integration into existing or new installations.

Correct installation of the valve is critical to ensure reliable operation and system efficiency. The valve is designed for use with non-aggressive fluids and is suitable for systems with glycol content below 50%. It is also compatible with potable water systems, making it versatile for a range of applications. The FF connection allows for straightforward integration into standard piping systems, and the 230V 50Hz power supply ensures compatibility with standard electrical infrastructure in European installations.

The switching time of 12 seconds at 90°C is a key factor in determining the valve’s suitability for specific applications, particularly where rapid response is required. The operating voltage of 230V 50Hz ensures compatibility with standard European electrical systems. The temperature range of +2°C to +110°C allows the valve to be used in a wide range of heating media conditions. The FF connection type simplifies installation and ensures secure, leak-free connections. The maximum ambient temperature of +55°C is important for determining the valve’s placement and the need for additional cooling or insulation in high-temperature environments.

Installation and connection

Installation of the DN20 zone valve requires careful attention to the connection type and system compatibility. The FF (female-female) connection allows for direct coupling with standard piping, using appropriate fittings and seals to prevent leaks. The valve should be installed in a position that allows for easy access for maintenance and manual override. It is important to ensure that the electrical supply is correctly wired and that the control system is properly integrated with the valve’s actuator.

Common installation mistakes include incorrect orientation of the valve, which can affect flow direction and performance, and failure to secure the electrical connections properly, which can lead to operational issues. Installers should also verify that the system pressure does not exceed PN 10 and that the media being used is within the specified temperature and chemical compatibility limits.

Compatibility and accessories

This zone valve is designed to work with standard heating system components, including thermostats, controllers, and actuators. It is compatible with systems using glycol-based media with a concentration below 50% and is suitable for potable water applications. When installing, it may be necessary to order additional components such as mounting brackets, sealing rings, or control modules, depending on the system configuration.

Technical background for designers

The valve operates using an electric actuator that opens and closes the valve in response to control signals. The actuator is powered by a 230V 50Hz supply and is designed to provide precise control over the flow of heating media. The valve body is constructed to handle media temperatures up to +110°C and is suitable for use in systems with glycol content below 50%. The FF connection ensures compatibility with standard piping systems and allows for secure, leak-free installation. The valve’s performance is influenced by the system pressure, media type, and ambient temperature, all of which should be considered during the design phase to ensure long-term reliability and efficiency.

Service and operation

Regular inspection of the valve is recommended to ensure continued performance. This includes checking the electrical connections for signs of wear or damage and verifying that the valve operates smoothly in both manual and automatic modes. The FF connection should be inspected for leaks or signs of corrosion, particularly in systems using glycol-based media. No specific service intervals are provided in the technical data, but it is advisable to perform routine checks in accordance with standard maintenance practices for heating system components.
