Thermodrive TELVA-2

DESCRIPTION

• 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.
