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.
