Continuous emptying of the dust collector hopper

NRSZ3 rotary valve with ATEX certificate St1 and St2
The rotary valve type NRSZ3 is used for continuous emptying of material from the dust collector.

The rotary valve can be used for emptying of several non-adhesive material types. Max. particle size for the NRSZ3 is 3 x 3 x 10 mm (.1 x .1 x .4 in.)

NRSZ rotary valves 10, 20 and 30
The NRS type rotary valve is used to transfer material between two separate systems. In pneumatic conveying systems discharge is usually required from the filter or cyclone to the silo, at atmospheric pressure. This is an ideal application for the NRS type rotary valve.

The rotary valve can be used for most material types, though the particle size must not exceed 13 x 13 x 13 mm (.5 x .5 x .5 in).
