The 81519335 is a miniature solenoid valve with a 3/2 normally closed (NC) function, intended for pneumatic control in potentially explosive atmospheres. This valve operates on a nominal 24 Vdc supply (from a 12 to 28 Vdc source) with a maximum power consumption of 0.70 W. It is designed for use with air or inert gases within a working pressure range of 1 to 7 bars and features a 0.5 mm orifice, delivering a flow rate of 12 NL/min at 6 bars. Certified for intrinsic safety (Exia II CT6), this valve is suitable for control systems in hazardous gas and dust environments when connected to an approved safety barrier.
