Asco Joucomatic has launched non-electrical, ATEX-certified pneumatic products for use in potentially explosive gaseous and dust-laden atmospheres. Asco’s non-electrical ATEX range covers zones 1-21 /2-22, with certification for zone 0-20 available on magnetic detectors used with PEC and PES cylinders. The range overall is extremely comprehensive, including air service units, spool valves, special interface namur valves, direct operating solenoid valves, pilot valve islands with field-bus control, and pneumatic cylinders with mountings and magnetic detectors. All these products are certified individually by ensuring that all metal surfaces, which could come into contact with an explosive atmosphere are earthed. On most components earthing continuity is achieved by removing part of the surface treatment, ensuring direct contact to metal parts.
