The preconfigured fail-safe circuit in the ready-to-install control cabinet is a safe and low-cost alternative when it comes to fail-safe technology. It replaces a single-acting actuator and guarantees that the actuator assumes a predefined safety position in the event of a pressure and/or power failure.

The pneumatic extension modules VTOP from Festo enable custom closed-loop control solution designs in combination with a positioner, all without any external piping and the leaks associated with it. Compared with conventional solutions, cost savings of up to 30% are possible with the VTOP. And installation takes just a fraction of the time.

Dosing, mixing, filling – the number of control applications in the process industries is steadily growing and demands high-performance positioners for process valves. Nowadays, extensive diagnostic options such as a pressure-assisted partial stroke test are vital for reliable operation. The new positioner CMSH from Festo for single-acting and double-acting actuators is therefore the perfect highly dynamic, low-wear positioning system for linear ...
