Thermostatic valve RA-N, three-way - left, for two-pipe central heating systems, with preset setting. 013G0234

The RA-N thermostatic valve is a component designed to regulate temperature in two-pipe central heating systems. Its three-way, left-hand design provides installation flexibility and adaptation to various radiator configurations. Made of nickel-plated brass, this valve guarantees durability and corrosion resistance.

The RA-N valve is characterized by a wide flow range – from 13 to 285 liters per hour at a pressure drop of 10 kPa, and from 15 to 349 l/h at 15 kPa. The Kvs value is 0.9, which allows for precise adjustment of the radiator's thermal output to the room's needs. Thanks to the pre-setting option, the valve allows limiting the stroke and optimizing the operation of the installation, especially in systems with different types of radiators or with variable hydraulic
