The new Atex approved 67 Series of direct-acting solenoid valves from Midland-ACS has been developed for use in corrosive and hazardous environments in the petrochemical, process, chemical, oil, gas and food industries. The marine grade (316L) stainless-steel valves are for general-purpose piloting, diverting or mixing tasks with gases, air and light oils. Available in three pipe sizes of 0.635, 0.952 and 1.27cm NPT, and rated for operation up to 20bar (with 10bar maximum differential), the solenoid valves offer high degrees of ingress protection – IP65 on standard enclosures and IP67 on explosion-proof, Atex certified enclosures. The valves use internal parts of 316 stainless steel and seals of Nitrile (standard) or optional Viton and EPDM materials. These combinations let the valves be used on gases, air and light oils across ambient temperatures from – 50 to +70C. The valves can be supplied either as discrete units or as part of fully designed, assembled and tested systems in stainless steel or marine grade flameproof enclosures.
