An actuator is a device that produces rotary or linear motion for various purposes. It requires an energy source and provides the basic mechanism through which a control signal operates. Metaval sells and supplies a wide range of industrial actuators in Australia.

There are two main categories of actuators - linear and rotary. A linear actuator can move forward and backwards on a single plane, while a rotary actuator rotates on a plane, as the name suggests.

A double acting actuator combines two single-acting actuators. Metaval has become a trusted supplier in Australia of the valbia pneumatic actuator, which is a good example of this.

The energy source of an actuator can be electrical, pneumatic, hydraulic or mechanical. Portable electric actuators are quite convenient for operating all kinds of valves.
