Thermostatic double control valve - direct, 1/2" x EK

Product detailed description

Thermostatic double control valves are essential components in heating systems where accurate temperature management is required. These valves are commonly used in residential and commercial buildings, particularly in systems that require zoning or individual room temperature control. Installers and service technicians often encounter these valves in central heating applications, where they regulate the flow of hot water to radiators or underfloor heating circuits. The IVAR VD 2105 N model is designed for direct control systems and is suitable for use in systems with a nominal pressure of PN 10 and a maximum operating temperature of +120°C. It is typically installed in conjunction with thermostatic heads and is connected to copper or plastic piping using appropriate compression fittings.

The valve is rated for a maximum operating temperature of +120°C, making it suitable for use in high-temperature heating systems. The nominal pressure of PN 10 ensures compatibility with standard heating system pressures. The nickel-plated brass CW617N construction provides corrosion resistance and durability in wet environments. These parameters are critical for determining the valve's suitability for specific applications and for ensuring correct system sizing.Installation and connection The valve is connected to copper or plastic piping using compression fittings from IVAR (TR for copper, TA for Alpex, TP for plastic). The connection size is 1/2 inch on one side and EK (European coupling) on the other. The thermostatic head is attached using an M30 x 1.5 thread. During installation, it is important to ensure that the compression fittings are correctly tightened and that the piping is aligned to prevent stress on the valve body. A common mistake is using incorrect compression rings or fittings, which can lead to leaks or poor sealing. The valve should be installed in a position that allows for easy access to the thermostatic head for adjustment and maintenance.Compatibility and accessories This valve is designed to work with thermostatic heads that have an M30 x 1.5 thread. It is compatible with copper, Alpex, and plastic piping when used with the appropriate compression fittings. To complete the installation, the correct type of compression fitting must be selected based on the pipe material. No additional products are required for basic installation, but it is recommended to have spare compression rings on hand for replacements or adjustments.Technical background for designers The valve operates on a thermostatic principle, where the flow of hot water is regulated based on the temperature of the surrounding environment. The nickel-plated brass CW617N body provides good thermal conductivity and resistance to corrosion, making it suitable for long-term use in wet environments. The valve is integrated into the system by connecting it to the heating circuit and attaching the thermostatic head. The service life and efficiency of the valve are influenced by the quality of the installation, the condition of the piping, and the accuracy of the temperature settings. Regular maintenance and correct system balancing are essential for optimal performance.Service and operation The valve requires minimal maintenance under normal operating conditions. It is important to periodically check the compression fittings for signs of wear or leakage. If the thermostatic head is not functioning correctly, it can be removed and replaced without affecting the valve body. There are no specified service intervals in the technical data, but it is recommended to inspect the valve during routine system maintenance.Frequently asked questions
