Electric actuator SMP28 with 230 VAC power supply and a 2-point control signal in a plastic enclosure. The actuator is without a return spring, so it is necessary to connect 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 rotary part of the actuator (valve) remains in the given 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 of 18 Nm
• running time of 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 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 indicates the operating status of the actuator. In active mode, the LED lights up under the rotary 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.
