HERZ thermostatic radiator valve set 1/2", axial, V772891

HERZ V772891 is an axial thermostatic radiator valve set designed for automatic radiator temperature control in two-pipe hot-water heating systems.

The set consists of a HERZ KLASSIK thermostatic head 1726006, a HERZ TS-90 axial thermostatic valve 1772891 and a HERZ RL-1 angle lockshield valve 1372441.

The HERZ KLASSIK thermostatic head is equipped with a liquid hydrosensor and automatically regulates the heating-water flow through the radiator according to the room temperature. The temperature adjustment range is 8–28 °C, with automatic frost protection at approximately 8 °C.

The HERZ TS-90 axial thermostatic valve is designed for connection to the radiator with a cone seal. Its universal design allows connection to threaded pipes or suitable compression adapters. The valve has a nominal size of DN15, a 1/2" connection and a Kvs value of 1.1 m³/h.

The HERZ RL-1 angle lockshield valve is installed on the radiator return and allows the radiator flow to be shut off when required. The axial configuration provides a compact installation and is particularly suitable where axial positioning of the thermostatic head is required.
