Page 4 INTRODUCTION This manual has been designed to guide you through the installation and use of the ATEX and IECEx VRX and VSX electric actuators. Read it carefully before using our products and keep it in a safe place. DESCRIPTION The VALVES electric actuators have been designed to allow the piloting of a 1/4 turn valve (or 180° in the case of a 3-position version).

The priority functioning mode of this actuator is electric. Be sure than the power supply is switched off before using the manual override. VRX models 1. Turn the knob to position MAN (counter-clockwise) and hold it in position. 2. Turn the outgoing drive shaft of the actuator with the help of an adjusting spanner.
