New explosion-proof linear actuator

PS Automation GmbH, Bad Dürkheim (Germany) extends its latest linear actuator range PSF/PSF-M with mechanical fail-safe function or manual override by an explosion-proof model.

The prototype of the new model PSF-EX was introduced at the Valve World Expo 2016 in Düsseldorf for the first time. In order to meet the growing demand of the market as well as to enhance the portfolio, PS Automation GmbH has further developed their latest linear actuator series PSF/PSF-M. Now, the PSF model is also available as an EX version with an explosion-proof enclosure. The new PSF-EX is determined for use in dust- and gas-explosive areas classed as zone 1 & 2 or 21 & 22. The PSF-EX is equipped with two compression housings that enclose the motor compartment and the control electronics. This encapsulation serves as an ignition protection measure. It makes sure that potential sources of ignition, e.g. sparks which may develop within the actuator do not lead to explosions in the ambient plants. This explosion-proof actuator of PS Automation meets explosion protection requirements for electrical equipment, equipment group II, equipment category 2 acc. to Directive 2014-34-EU (ATEX).
