Introduction to Intrinsically Safe Systems
Intrinsically safe operator. An intrinsically safe operator is designed to keep current draw to a minimum (29 mA) by accurately controlling plunger strokes. Also, since the pilot orifice is located in the sleeve rather than in the valve body, removal of the operator from the valve does not alter stroke tolerances or current draw.
