The solenoid valve and sequential control unit HE 8991 is used for pulse activation of solenoid valves in air pollution control systems. Each function as for example post-cleaning procedure of the industrial filter, time-controlled forced-cleaning and multiple pulse activation of a valve can be selected by the user as required. The HE 8991 has build-in test functions for checking individual valves, the complete line of valves, and a high-speed current check for detecting open- or short-circuits.
