Chesterton’s 1724E Control Valve Kits are specifically designed to be used on pneumatically actuated control valves. 1724E is best suited for services where operating temperature is steady state with minimal thermal cycling, and in applications where the stem friction from pure graphite packing is too high for the valve’s actuator. The kit contains all parts necessary to repack the valve in the field with Chesterton’s Live-Loading system. 

                                                                                                                                                                          The kit includes a 1724 5 ring die -formed PTFE packing set, a precut 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. 1724E should be utilized with live-loading in control valves to ensure effective long term sealing over many cycles.
