NRS 3 Rotary valves

The NRS type rotary valve is made with galvanised or stainless steel plate. The rotor has reinforced rubber blades, which provide an effective air lock between the inlet and the outlet. ATEX version the rotary valve type NRSZ is design as 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 the metal dust).

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

The rotary valve can be used for emptying of several non-adhesive material types. Max. particle size for the NRS3 is 3 x 3 x 10 mm (.1 x .1 x .4 in.).
The rotary valve should not work with highly abrasive dust:

Features:

• Robust construction
• Effective air lock between the inlet and outlet provided due to the special rubber blades.
