Festo VZWE-E-M22C-M-G34-200-H VZWE-E-M22C-M-G1-250-H Reverse jet pulse valves
Reverse jet pulse valves VZWE are piloted 2/2-way valves. They generate pulses of compressed air using a suitable solenoid coil for mechanically cleaning filters and dust filter systems. The valves are actuated using short electrical pulses. These pulses generate short pulses of compressed air at the output of the valve, which travel through the filter against the normal direction of flow of the filter system to release adhering particles from the filter.
