Möhlenhoff actuator Basic TAW 2004-00N80H-1S
The TAW 2004 is a thermoelectric actuator for opening and closing valves that can be used in heating, ventilation, and air conditioning systems. The TAW is controlled by a 230 V room temperature controller with a two-point output or pulse width modulation.
PERFORMANCE FEATURES
• Compact design, functional design
• Version in de-energized (NC)
• First-Open function
• Maintenance-free • Silent
• Function display (optional)
• Adjustment control on valve (only with function display)

FUNCTIONS
The actuating mechanism of the TAW 2004 operates with a PTC-heated expansion element and a compression spring. The expansion element is heated by applying the operating voltage, thereby moving the integrated tappet. The force generated by this movement is transferred to the valve tappet, thus opening or closing the valve.
When the operating voltage is switched on – after the dead time has elapsed – the valve opens smoothly due to the movement of the plunger. When the operating voltage is switched off and after the dwell time has elapsed, the valve closes smoothly due to the closing force of the compression spring. The closing force of the compression spring is matched to the closing force of commercially available valves and keeps the valve closed when de-energized.
Function display
The function display shows whether the valve is open or closed.
First-Open function
The TAW 2004 is delivered with the first-open function, meaning it is open without power. This enables heating operation during the shell construction phase, even if the electrical wiring for the individual room control system has not yet been completed. During subsequent commissioning, applying the operating voltage (for more than 6 minutes) automatically unlocks the first-open function, and the TAW 2004 is fully operational.
