Auma actuator

Click2Contact

Auma actuators are provided for distribution valves for mine backfill paste. The valves are designed to work with very high fluid pressure well down into gold mines, sometimes as deep as 1300 m.

The actuators are supplied in two distinct types: one with an alternating current supply and the other having a DC supply. The actuators feature a ruggedised build and are available in large sizes. The device also features a high operating torque to facilitate rapid closing times.

For DC operation, the system integrator will supply a control panel having control PLC and battery backup. The control panel determines how the actuator should work and whether the paste is going to one location or another.

In the case of AC operation, the actuator is supplied with its own motor control centre and local control functions. It still requires logical controls from a PLC or host computer.

It is common practice to remotely mount the Auma Controller nearby but still accessible and away from operating machinery or trucks passing by. To do this Auma supplies a 16 m remote mount cable set.
