Direct-acting solenoid valves for use in harsh environments
Introduced last month, these two intrinsically safe solenoid valves (photo) have Ex ia IIC T6 certification. The solenoid operators are designed for use on the 327 range of direct-operated solenoid valves, and are available in epoxy-coated aluminum or stainless steel. The solenoids are certified to ATEX, Category 1G/2D and Equipment Protection Level (EPL) Ga/Db. Both operators are IEC Ex approved and certified to IEC 61508 Functional Safety (SIL 3 capable). The 327 Series feature a brass, stainless-steel or aluminum body, and have a large flowrate (Kv = 0.45 m3/h), operate from 0 to 10 bars and require no minimum operating pressure. — ASCO Numatics Ltd., Skelmersdale, U.K.
