Thermostatic control head with contact probe - graduated scale 68 - 122°F (20–50°C)
Thermostatic valves are typically used for controlling the fluid flow to the
radiators of hydronic heating systems. They are composed of two parts:
a control head and valve body.
The control contains a liquid-filled thermostatic element that automatically
controls the opening of the valve to maintain room temperature at the
set value. This prevents unwanted room temperature rises, providing
considerable energy savings.
The valve body has NPT threaded connections: female threads to
connect to the system and union male threads to connect to the radiator.
These valves can also be used for isolating and balancing.
