The (WS)LPKF low-power pilot with Ex d certification is now available for the compact 551, 552 and 553 Series pilot valves. The valve is available with either an aluminum or stainless-steel enclosure, and with a power consumption of just 0.5 W at 24 V d.c., which is claimed to be the lowest consumption of any Ex d certified valve for the process industry. The low Wattage coil reduces battery drain and heat rise, minimizing wiring costs and provides energy savings, says the manufacturer. — ASCO Controls BV, Scherpenzeel, the Netherlands
