ASCO Numatics has introduced a low power version of its Series 327 Ex d solenoid valve which addresses the demand for lower power consumption solenoids. The new valve, which is suitable for applications up to 127V 50/60Hz and 125V DC, features a highly efficient solenoid with an optimised magnetic performance. The improved operation of the enhanced design has reduced the power consumption of the valves to just 1.8 watt (cold) and 1.5 watt DC (hot). Based on the principle of a balanced poppet type construction, Series 327 valves are ideal for demanding applications in the chemical, petrochemical and oil and gas industries. The valves are Exida and TÜV certified to IEC 61508 Functional Safety and can be used in safety applications up to SIL-4 (redundant) with the highest achievable PFD factor. Series 327 valves are 3/2 direct operated solenoid valves requiring no minimum operating pressure. The flameproof IP67 Ex d aluminium or 316 stainless steel enclosure is rated to II 2G/D Ex d IIC T6 Ex tD according to the latest ATEX and global IECEx standards.
