回水温度限制器传感器

FJVR 传感器

The return limiter type FJVR automatically controls the return temperature from radiators, convectors and floor heating pipes. In ventilation systems FJVR ensures a certain minimal circulation in the pipe system up to the heat exchanger. FJVR is a self-acting P-band regulator, used in 2- pipe systems with pump. Setting can be limited and locked. FJVR valve bodies are nickel-plated.

RTX（限制器）

Type RTX - a return temperature limiter, meaning that it senses and regulates the return flow in the radiator rather than the air temperature. Used on a towel rail, and set 5 -10 degrees above room temperature, the RTX sensor will keep the radiator warm - ensuring dry towels.
