self acting thermostatic sensor

FTC is a self-acting thermostatic sensor used for flow temperature control of floor heating and radiator heating systems.

The water temperature is measured by a surface sensor, which is easily mounted on the pipe by means of a strip (enclosed with the product). The snaplock connector of the sensor element secures a firm connection to the valve.


Type: Self-acting thermostatic operator with 6’ 6” (2 m) capillary and strap on sensor. Celsius temperature scale on dial.
Maximum ambient temperature: 150°F (65°C)
Maximum flow temperature: 250°F (120°C)
Capillary tube length: 0 to 6.5’ (0 - 2.0 m)
