The SMP28-10 electric actuator with 230 VAC power supply and a 2-point control signal 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:

• 230 VAC power supply
• SPDT control
• actuator without return spring
• direct installation on the valve
• six-core cable with a length of 80 cm
• torque 12 Nm
• run time 10 s
• manual control and position indication
• LED operation indication
• built-in auxiliary contact
• maintenance-free

Manual Control:

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

Operation Indication:

The LED light indication shows the operating status of the actuator. In active mode, the LED lights up under the rotating ring, and in standby mode, the LED is off.

For Ball Valves:

• two-way - I/VBZ
• three-way - TG/VBZ

Connection Options:

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