Thermodrive is intended for opening or closing valves in heating, cooling or air conditioning systems. It is also suitable for use in a floor heating or ceiling cooling manifolds.

Available in NO (open without voltage), NC (closed without voltage) and for 230 V and 24 V.

The internal principle of operation of thermodrive mechanism = its movement so that the valve opens/closes is provided by an electric heating element with expansion material, which expands due to temperature changes in the supply voltage.

Thermodrive is maintenance-free and works completely silently.

Thermodrive is fi tted with a metal nut M30 x 1.5, thanks to which it becomes a 100% fixed part of the valve with this corresponding thread size after installation.

The stated nut size predetermines the use of a thermocouple with valves from manufacturers such as Herz, HoneyWell, Danfoss, Oventrop and others.

Telva thermo drive:

is characterized by absolutely quiet and maintenance-free operation

is designed for installation - control of heating and cooling systems

method of mounting the actuator on the controlled valve using an M30 x 1.5 nut

any working position

Type of use:

Floor heating – the RFTC-50/G wireless controller measures the room temperature and, based on the set program, sends a command to the RFSA-66M switching element to open/close the TELVA thermodrive on the distributor.
