Thermostatic valve RA-N 25 straight, with pre-setting 013G0038

Thermostatic valve for precise heating control

The RA-N 25 thermostatic valve is a reliable solution for two-pipe central heating systems. Its simple construction and pre-setting option allow for optimal system balancing, ensuring thermal comfort and reducing operating costs. It is an element that will be appreciated by both professional installers and end-users looking for an effective way to control the temperature in their homes.

Construction and application

The RA-N 25 valve is designed for mounting on radiators with a 1 inch (25) connection. Made of high-quality materials, including nickel-plated brass, it guarantees durability and corrosion resistance. The use of a valve with a pre-setting allows for precise adjustment of the heat flow, which is crucial for the proper functioning of the entire heating system. This avoids problems with uneven heating of individual rooms. The valve works with a wide range of Danfoss RA series thermostatic heads - gas, liquid and decorative, as well as electronic living eco and living connect models.

Key features and benefits

• Precise adjustment: The pre-setting option allows for accurate adjustment of the heat flow to the needs of a specific radiator and room.
• Versatility: Designed for two-pipe central heating systems, compatible with various types of Danfoss thermostatic heads.
• Durability: Made of high-quality materials, including nickel-plated brass, ensuring corrosion resistance and long life.
• Energy saving: Optimizing heat flow translates into reduced energy consumption and lower heating costs.
• Easy installation: The "click" system facilitates quick and secure connection of the valve to the thermostatic head.
• Flow rate: The valve provides a water flow rate of 32 to 542 l/h depending on the pressure in the installation (at 10 kPa: 32-443 l/h, at 15 kPa: 39-542 l/h).
• Kv value: Flow regulation takes place in the range of Kv values from 0.1 to 1.4 (Kvs value: 1.4 and Kv2 value: 1.04), allowing for precise matching to the radiator characteristics.
• Protection: It has a dust cover protecting against dirt and mechanical damage.

The RA-N 25 valve is a proven component of heating installations, providing comfort and energy efficiency for years to come. Its solid construction and precise operation make it an ideal choice for both new installations and modernization of existing heating systems.
