0 - Impactor Handwheel, the mechanism is based on transmitting the momentum generated by the mass of the handwheel through the impact/impulse generated during the snap closure action of the handwheel. This type of handwheel is used when a standard handwheel cannot create enough closing force to effect a seal.
1 - Globe valve Stem Nut replaceable in the line.
2 - Revolving rising stem with precision ASME thread.
3 - Stem Packing is designed for optimum control of fugitive emissions leakage to the atmosphere. The ultra low emission leakage rate is assured by the fine finish in the stem, the reduced diametrical clearences and the stem straightness control.
4 - Body to Bonnet Joint designed to apply a uniform load to the gasket to assure a leak proof seal.
5 - Backseat designed to relieve back pressure on the stem packing when fully seated. Replacing stem packing under pressure is not recommended.
6 - Conical Disc, integrally guided to assure true alignment between disc and valve body. The loose disc design allows the disc and seat ring sealing surface to seat correctly without damage.
7 - Stellited Seat Ring, providing increased resistance to ware, abrasion and erosion of the sealing surface.
8 - Seat ring is seal welded to provide a bubble tight joint..
