Continuous emptying of the dust collector hopper.
The NRSZ 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 NRSZ type rotary valve.The rotary valve can be used for emptying of several non-adhesive material types, also combustible dust. Max. particle size for the NRSZ 3 is 3 x 3 x 10 mm (.1 x .1 x .4 in.)The rotary valve should not work with highly abrasive dust.The NRSZ rotary valve is made explosion pressure shock resistant. It prevents the transmission of the explosion effects, pressure wave, flame and sparkles until its maximum reduced explosion pressure Pred,Max. in both directions of the divided space with dangerous atmosphere of the flammable dust (except metal dust).The rotary valve should not work with capacity more than 60% of max.
