SMP48 electric drive with 24 VAC power supply with 0-10 V / 4-20 mA control signal in a plastic housing. The drive is without a return spring, so it is necessary to connect both a switching phase for controlling the valve and a permanent phase so that the drive (valve) returns to its original position after disconnecting the control signal. If the power supply fails, the rotating part of the actuator (valve) remains in the given position. When the valve is fully open, the auxiliary switch is activated and remains active until the valve is closed.

Use:

• heating systems
• air conditioning systems

• three-way - TG/XBZ

Connection options:

The drive can be connected directly to the valve without an adapter.
