Thermostatic valve, straight, SX insert, with pre-setting, DN15, external thread 3/4 inch, with radiator connection with metal-to-metal seal V2026DSX15

Thermostatic valve for precise regulation

This thermostatic valve with SX insert is a key element in the heating system, providing thermal comfort and efficient energy management. Designed for two-pipe installations, it works well both in new buildings and during the modernization of existing systems. Its versatility and quiet operation make it an ideal choice for both professional installers and end-users.

The valve is designed for mounting on the radiator supply, although installation on the return is also possible. Made of high-quality brass, it guarantees durability and corrosion resistance. The use of a metal-to-metal sealed radiator connector ensures a tight and reliable connection.

Functionality and technical parameters

The valve offers a wide range of flow rates, adjustable with a setting key, allowing for precise adjustment to the needs of a specific room. The pre-setting option makes it easier to optimize the operation of the heating system. Additionally, the valve has a surface protection in the form of nickel plating, which increases its resistance to external factors.

• Flow rate: 20 – 170 l/h (for min. 10 kPa) – provides an adequate amount of heat depending on demand.
• Kv value: 0.063 – 0.54 – allows for precise regulation of the flow of heating medium.
• Thread: 3/4 inch (external) and 1/2 inch (for radiator) – enables easy installation in standard installations.
• Housing material: Brass – guarantees durability and corrosion resistance.
• Dust cover: Provides protection against dirt and mechanical damage.
• Reverse flow direction: Possibility of installation in various configurations without affecting the functionality of the valve.

Advantages for the installer and user

This thermostatic valve is not only solid workmanship and precise operation, but also a number of conveniences for the installer and benefits for the end-user:

• Easy installation: Standard threads and connector facilitate quick and trouble-free installation.
• Insert replacement possible: In the event of a failure or the need to change the valve characteristics, only the insert can be replaced without the need to disassemble the entire installation - requires a dedicated service tool.
• Quiet operation: Provides comfortable use without unpleasant sounds.
• Durability: Made of high-quality materials guarantees a long service life.
• Compatibility: Can cooperate with various types of thermostatic heads (M30 x 1,5).
• System balancing: Limiting the maximum flow to 130% of the nominal flow helps maintain hydraulic balance in the heating system even with large temperature differences in individual rooms.
