Chesterton® AWC800 22K Piston Seal, 22K Rod Seal, 21K Wiper and 20K Static D-ring are used in place of the Fabric-Reinforced Neoprene Rubber. AWC800 is a diamine-cured thermoset polyurethane which is a proven material to resistant ragging-out into fibers. Therefore, the valves will no longer be clogged, thereby preventing frequent shutdowns.
At the same time, AWC800 is abrasion-resistant, wear-resistant, extrusion-resistant, non-absorbent, and operates with low-friction because of its molybdenum disulphide lubrication. Also, to guard the cylinder against side loading and metal-to-metal abrasion on the adjacent metal surfaces (such as those on the piston/barrel interface and rod gland/rod interface), Chesterton® 18K GNF bearing bands are introduced both on the piston and rod gland.
Overall, aside from the prevention of clogging on the valve and prevention of wear between metallic parts, the main goal of the changes in the design is to lengthen the service life of the cylinder and ensuring leak-free service during operation.
