• Surface Finishes and Close Tolerances ofstem and chamber provide optimal sealingsurfaces and minimize wear.• Narrow Packing Rings reduce the effect ofpacking shrinkage, thereby reducing thefrequency of packing gland adjustment.Since force = pressure x area (F = P x A),by keeping the packing area to a minimum,there is less force being exerted by thesystem fluid, making it easier to contain.• Integral Gland Wrench, standard on allCLAMPSEAL® globe and gate valves,provides immediate gland/packingadjustment capability.
