The 5800E WedgeSeal is a combination packing set that utilizes Chesterton’s unique wedge shaped, die-formed sealing set along with our 477-1 braided carbon end rings. The 5800E set has been proven to seal to extremely low VOC emissions levels. The unique wedge shape of the sealing rings provides more efficient transfer of gland load to the packing and makes the set more responsive to gland adjustments. Reduced stem friction ensures that the valve will respond to system changes more rapidly and precisely. Passive corrosion inhibitors are impregnated in the packing set to help prevent electrolytic pitting. The WedgeSeal set also passes API 589 fire testing thus ensuring maximum safety in hazardous services.                                                                                                                                                                                                    Chesterton 5800E Control Valve Kits are specifically designed to be used on pneumatically actuated control valves. The kit contains all parts necessary to repack the valve in the field with Chesterton’s Live-Loading system; the set includes a 5800E packing set, a pre- cut carbon spacer, pre-engineered live-load assemblies and new gland studs and nuts. All packing rings and spacers are cut to allow installation without removal of the valve actuator, simplifying the valve repacking procedure in the field. The Live-Load assemblies are easily identifiable by their uniquely shaped outer guide, and are simple to install and use. Simply fit the assembly over the stud and tighten the gland bolt until the flat washer is flush with the top of the outer guide. No torque wrench is required.
