Thermostatic single-point fitting - corner, 1/2" x EK

Product detailed description

This thermostatic single-point valve is commonly used in residential and commercial heating systems where pipe radiators are connected to central heating circuits. It is suitable for both single and two-pipe systems and allows for flexible installation configurations. The valve is typically found in underfloor heating systems, panel radiators, and other single-point connection applications. Installers must ensure the system design allows for correct flow and return connections to maintain balanced operation.

The valve is designed for use in systems with copper or plastic pipework, using compression fittings to ensure a secure and leak-free connection. It is particularly useful in systems where space is limited and a compact, corner-mounted solution is required. The valve’s thermostatic control allows for precise temperature regulation at the point of use, reducing the need for additional balancing valves or manual adjustments.

Technical parameters

Material	nickel-plated brass CW617N
Operating temperature	+100 °C
Nominal pressure	PN 10
Weight	0.602 kg
Code	IVA81210
Brand	IVAR

The maximum operating temperature of 100°C and nominal pressure rating of PN 10 are critical for determining the valve’s suitability for a given system. These parameters ensure the valve can handle typical domestic heating conditions without degradation. The nickel-plated brass CW617N material provides good corrosion resistance and mechanical strength, making it suitable for long-term use in wet heating environments.

Installation and connection

To install the valve, first ensure the pipework is correctly sized and aligned with the valve’s 1/2 inch connection and M30 x 1.5 thread. The valve is connected using compression fittings, which must be tightened according to the manufacturer’s instructions. It is important to verify that the valve is mounted in the correct orientation to allow for proper flow direction and to prevent pressure loss. Common installation errors include incorrect thread engagement, over-tightening of fittings, and failure to check for alignment before securing the connections.

Compatibility and accessories

This valve is compatible with copper and plastic pipework when used with the appropriate compression fittings. For copper connections, IVAR.TR fittings are recommended; for ALPEX, IVAR.TA fittings; and for plastic, IVAR.TP fittings. These must be ordered separately. The valve can be used in both single and two-pipe systems, allowing for flexible integration into existing or new heating layouts. It is important to ensure that the selected fittings match the pipe material and size to avoid leaks or performance issues.

Technical background for designers

This valve operates by using a thermostatic element to regulate the flow of hot water through the radiator based on the ambient temperature. The nickel-plated brass body provides good thermal conductivity and resistance to corrosion, ensuring long-term reliability. The valve is designed to integrate into both single and two-pipe systems, with the ability to switch between supply and return connections depending on system requirements. The material choice and connection type ensure compatibility with a wide range of pipe materials and installation methods. The service life and efficiency are influenced by the quality of the installation, the condition of the pipework, and the system’s overall pressure and temperature stability.

Service and operation

Regular inspection of the compression fittings and connections is recommended to ensure a leak-free operation. No specific service intervals are provided in the brief, but it is good practice to check for signs of wear or corrosion during routine system maintenance. The thermostatic element should be tested for responsiveness to temperature changes. If the valve shows signs of reduced performance or leakage, it should be replaced immediately to avoid system inefficiencies or damage.
