STYLE 24AExpanded Valve Stem Packing
Description and ApplicationsStyle 24A valve stem packing utilizes 100% pure expanded PTFE in a unique braid-over- braid-over-core construction with a round cross section. This unique construction produces a firm but conformable packing that handles higher pressures than competitive products.
Style 24A a very workable packing which conforms easily to worn valve stems and stuffing boxes, yet forms a very high density packing when compressed. It will handle virtually all chemicals in the 0 - 14 pH range and will not contaminate flow media. It is ideal for service in the food processing, beverage and pharmaceutical industries and is also commonly used for pulp and paper and general chemical applications.
