Datasheet download
Download PDFBelimo GRK actuator for ball valves with electrical fail-safe function on the capacitor principle.
In the event of a power interruption, the tap turns the energy stored in the capacitors to the starting position. The principle of fail-safe function is therefore different from conventional spring actuators.
The actuator requires a certain amount of time to charge on the operating capacity. The charging time of the actuator depends on the time when the power supply was disconnected. However, the charging time does not exceed 20s, which corresponds to a power failure time of more than 10 days.
The actuator is delivered completely discharged at the factory. It requires approx. 20s to charge the capacitors to reach the required voltage level.
