Thermostatic valve RA-N 25 angled, with preset 013G0037

Angular thermostatic valve with pre-setting – precise regulation and energy saving

This angular thermostatic valve RA-N 25 from Danfoss is a reliable solution for precise temperature control in heating systems. Designed for efficiency and durability, it is ideal for both new and modernized installations. Its construction allows for optimal system balancing, which translates to thermal comfort and reduced heating costs.

The valve is designed for installation in two-pipe systems where even heat distribution is crucial. The nickel-plated finish provides corrosion resistance and an aesthetic appearance. The white pre-setting button allows you to adjust the flow rate to the specifics of a given radiator and room, which is especially important with differences in heat demand.

Characteristics and application

The RA-N valve is characterized by a flow rate range of 32 to 443 l/h at a pressure of 10 kPa and 39 to 542 l/h at a pressure of 15 kPa. The Kv value in the range of 0.1 - 0.73 and Kvs equal to 1.4 allow for precise adaptation to the installation needs. Using a valve with a pre-setting allows you to obtain the nominal flow rate, which guarantees optimal balancing of the entire heating system. This makes it possible to avoid problems with underheated or overheated rooms.

The valve has dust protection, which increases its durability and reliability in harsh operating conditions. It is compatible with RA 2000 series thermostatic heads (gas, liquid and decorative), providing a wide range of options for choosing the right temperature control. Made of high-quality materials, it ensures long-lasting and trouble-free operation.
