Dynamic thermostatic valve - axial, 1/2" x EK

Product detailed description

This axial dynamic thermostatic valve is commonly used in residential and commercial heating systems where precise flow control and thermal regulation are required. It is typically installed in radiators or underfloor heating circuits to manage heat distribution based on room temperature. The valve is designed for use in systems with copper or plastic piping and is compatible with various connection types. Installers should consider the valve’s operating parameters and connection requirements when integrating it into a system.

The valve is suitable for applications where a pre-set flow rate is required, and it can be adjusted to maintain consistent thermal performance across different zones. Its axial design ensures smooth operation and minimal pressure drop, making it ideal for use in balanced heating systems. The valve is often used in conjunction with thermostats and room controllers to achieve accurate temperature regulation.

Technical parameters

Nominal pressure	PN 10
Weight	0.273 kg
Code	501192
Brand	IVAR

The operating temperature limit of 120 °C and nominal pressure rating of PN 10 are essential for determining the valve’s suitability for specific heating systems. The nickel-plated brass CW617N material provides corrosion resistance and durability in hot water environments. The pre-set Kv value allows for accurate flow control, which is important for system balancing and energy efficiency.

Installation and connection

The valve is connected using 1/2 inch EK threading and requires compatible fittings such as IVAR.TR for copper, IVAR.TA for ALPEX, and IVAR.TP for plastic piping. The M30 x 1.5 thread on the head allows for the attachment of control heads or actuators. During installation, it is important to ensure that the valve is oriented correctly and that the connection is secure to prevent leaks. Common installation mistakes include incorrect orientation, improper tightening, or using incompatible fittings, which can lead to system inefficiency or failure.

Compatibility and accessories

This valve is compatible with copper and plastic piping systems and requires specific connection fittings depending on the material. It is recommended to use IVAR.TR, IVAR.TA, or IVAR.TP fittings for secure and leak-free connections. For control and regulation, a compatible control head or actuator with an M30 x 1.5 thread is required. No alternative or related products are specified in the brief.

Technical background for designers

The valve operates based on a dynamic thermostatic principle, where the internal mechanism adjusts the flow rate in response to temperature changes. The nickel-plated brass CW617N material offers good thermal conductivity and resistance to corrosion, ensuring long-term performance in heating systems. The valve integrates into a system by maintaining a pre-set flow rate, which helps in achieving balanced heat distribution. The efficiency and service life of the valve depend on the quality of the installation, the compatibility of the piping material, and the correct setting of the pre-set flow rate.

Service and operation

The valve requires minimal maintenance due to its robust construction and sealed design. Regular checks should include verifying the tightness of the connections and ensuring that the valve is operating within the specified temperature and pressure limits. No specific service intervals are provided in the brief, but any signs of leakage or reduced performance should be investigated promptly to prevent system issues.

Frequently asked questions

Can this valve be used with plastic piping systems?
Yes, the valve is compatible with plastic piping when connected using the IVAR.TP fittings. The EK connection allows for secure and leak-free installation.

Is it possible to adjust the pre-set flow rate after installation?
No, the valve has a pre-set Kv value that cannot be adjusted after installation. It is important to select the correct model with the required flow rate before installation.

What is the maximum operating temperature of the valve?
The valve is rated for operation up to 120 °C, making it suitable for most heating systems that use hot water as the heat transfer medium.

Can this valve be used in a system with a pressure higher than PN 10?
No, the valve is designed for nominal pressure up to PN 10. Using it in a system with higher pressure may lead to failure or reduced service life.
