Packing Arrangements. SINGLE PACKING. This is an economical seal for many applications. Single packing consists of a stack of packing at the top of the packing box supported by either a spring or gland follower. Spring packing can be accomplished by having the packing follower drawn against the bonnet to compress the spring. (This is a variation on the live loaded packing discussed later in this section.) Figures 19 and 20 show single packing arrangements for sliding stem and rotary valves. This type of packing is not adjustable. Springs are not available in all alloy materials.
