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% fi xed 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 thermo drive on the distributor
