Electric actuator SMP48 with 24 VAC power supply and control signal 0-10 V / 4-20 mA in a plastic casing. The actuator is without a return spring, so it requires both a switching phase for valve control and a permanent phase to return the actuator (valve) to its original position after the control signal is disconnected. If the power supply fails, the rotating part of the actuator (valve) remains in its current position. When the valve is fully open, an auxiliary switch is activated and remains active until the valve is closed.

Application:

• heating systems
• air conditioning systems

Features:

• 24 VAC power supply
• SPDT control
• signal 0-10 V / 4-20 mA
• actuator without return spring
• direct installation on the valve
• six-core cable, 80 cm long
• torque 15 Nm
• running time 60 s
• manual control and position indication
• LED operation indication
• built-in auxiliary contact
• maintenance-free

Manual control:

By pressing button "A", it is possible to adjust the actuator by turning the dial "C" between positions 0...10. The dial can be pulled out for easier access and pushed back after setting to a new position. 

Operation indication:

The LED light indicates the operating status of the actuator. In active mode, the LED lights up under the rotating dial, and in idle mode, the LED is off.

For ball valves:

• two-way - I/VBZ (DN 40-50)
• three-way - TG/XBZ

Connection options:

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