Thermodrive is intended for opening or closing valves in heating, cooling, or air conditioning systems. It is also suitable for use in 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 fitted 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 thermo drive on the distributor
