The Thermoelectric Valve Drives TSA/K are suited for opening and closing valves in Heating, Ventilating and Air-Conditioning (HVAC) systems. The devices are normally closed available in 230 V AC and 24 V AC/DC with pluggable connecting cable. The shapely housing protects the device against splash water. The device is especially suited to control radiators, converter heaters and cooling ceilings for single room temperature controlling. The valve drive can be controlled with the Electronic Switch Actuator ES/S or with the Electronic Relay ER/U in combination with the Universal Interface US/U and a Room Thermostat. The easy and quick snap-on mounting on all common valves occurs via Valve Adapters VA/Z.
