Thermostatic double control valve - three-axis - L, 1/2" x EK

Product detailed description

This thermostatic double control valve is commonly used in residential and commercial heating systems to regulate the flow of hot water through radiators. It is particularly suited for systems where precise temperature control is required, such as in central heating installations with individual room thermostats. The three-axis design ensures stable operation and accurate modulation of flow in response to temperature changes. Installers typically use this valve in systems with copper, steel or plastic piping, where compatibility with different connection types is essential.

As a double control valve, it allows for both manual and automatic regulation, making it suitable for systems that require fine-tuned adjustments. The valve is often installed in conjunction with thermostatic radiator heads and is used in applications where space constraints or system layout require left-hand orientation. The compact design and standard connection sizes make it a versatile option for a range of heating system configurations.

Technical parameters

Installation and connection

Installation requires careful alignment of the three-axis mechanism to ensure smooth operation. The valve connects via a 1/2 inch thread and is compatible with various connection types, including steel, copper and plastic piping. The M 30 x 1.5 thread on the connection head allows for secure fastening. Installers should verify that the valve is oriented correctly for left-hand installation and that the sealing surfaces are clean and undamaged before tightening. Common mistakes include incorrect orientation, which can lead to restricted flow, and over-tightening, which may damage the internal components.

Compatibility and accessories

This valve is compatible with a range of connection accessories, including IVAR.TR clamping fittings for copper, TA for ALPEX and TP for plastic piping. These fittings must be ordered separately and are essential for ensuring a secure and leak-free connection. The valve is also designed to work with standard thermostatic radiator heads and can be integrated into systems with manual or automatic temperature control. For left-hand installation, the valve must be positioned correctly to avoid interference with adjacent components.

Technical background for designers

The three-axis design of the valve allows for precise modulation of flow in response to temperature changes. The internal mechanism is made from nickel-plated brass (CW617N), which provides good corrosion resistance and mechanical strength. The valve operates by adjusting the flow area in response to the temperature of the surrounding medium, ensuring that the radiator maintains the desired heat output. The choice of connection type and orientation affects the overall efficiency and longevity of the system. Proper integration into the heating circuit is essential to avoid pressure drops and ensure even heat distribution.

Service and operation

Regular inspection of the valve's connection and sealing surfaces is recommended to ensure continued performance. No specific service intervals are provided, but any signs of leakage or restricted flow should be investigated promptly. The valve should be checked for proper orientation and alignment, and the connection fittings should be verified for tightness. If the valve is not operating smoothly, the internal mechanism may require cleaning or adjustment. In cases of persistent issues, the valve should be replaced to maintain system efficiency.
