Airlocks feature abrasion resistant packing rings.
July 27, 2006 -
Suited for fine, free-flowing, and abrasive chemical powders, PAV Series Airlocks have abrasion resistant packing rings and form-fitting, positive seal around shaft where smooth shaft finishes minimize cutting action on packing rings. Additional packing rings are included for sealing against high internal valve pressures. Self-adjusting packing glands are replaced with manually adjusted packing glands capable of additional pressure.

Prater Introduces New Seal Design for Airlocks
For Fine, Free-Flowing and Abrasive Chemical Powders
BOLINGBROOK, ILL. (July 24, 2006) - Prater-Sterling is pleased to offer a new heavy-duty shaft seal design for their PAV Series Airlocks with a few significant differences from their standard seal design.
New abrasion resistant packing rings provide additional wear resistance against abrasive powders and a more form-fitting, positive seal around the shaft where smoother shaft finishes reduce cutting action on the packing rings. Additional packing rings are included for sealing against higher internal valve pressures.
Tighter tolerances provide better support for the packing and throttle air leakage from within the valve. Lastly, the self-adjusting packing glands exclusively associated with Prater Airlocks are replaced with manually adjusted packing glands capable of additional pressure.
Prater also offers the option of a new air purge kit with flow meters and oversized lines for proper flow to the lantern rings.
In combination, the features mentioned above are an effective way of sealing the shaft when handling abrasive powders, or when the valve discharges to a positive pressure, pneumatic conveying line. To ensure success, Prater offers the services of their skilled staff to assess specific applications and recommend ideal operating parameters.
Prater also offers Ceramic airlocks, Dust Collector Series (DCS) airlocks, as well as Quick-Take-Apart (QTA) airlocks. Prater-Sterling's headquarters are located in Bolingbrook, Ill., with additional operations in Sterling, Ill. For more information about Prater-Sterling, please refer to www.prater-sterling.com.
