Cast Steel GLOBE VALVE Bolted Bonnet, OS&Y www.migzvalve.com 1) Stem Nut, replaceable in line to avoid shutdown of pipeline process. 2) Rising Stem, with precision single or double thread for quick operation. Surface finish suitable to seal properly to obtain low fugitive emissions. 3) Stem Packing, designed for optimum control of fugitive emissions leakage to the atmosphere. The ultra-low emission leakage rate is assured by the polished finish stem sealing area, the reduced diametrical clearances and the stem straightness control. 4) Backseat, designed to relieve back pressure on the stem packing when fully sealed. Replacing stem packing under pressure is not recommended. Hard faced backset is available for severe service as per customer requirements. 5) Body to Bonnet ring type joint, designed to apply a uniform load to the gasket to assure a leak proof seal.. 6) Conical Plug type 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) Stellite Seat Rings, to provide increased resistance to wear, abrasion and erosion of the sealing surfaces. 8) Two pieces arrangement gland flange and stem packing bushing for self-alignment to avoid stem damage. 9) Globe valve, supplied with handwheel or gear operated.
