FEATURES - BENEFITS Non rotating vee / ball tip design - which forms a bearing joint with the stem eliminates rotation between plug and seat at closure. This prevents scoring and galling up the valve seat and ensure long life in repetitive shut off service. Safety bonnet lock - prevents accidental disassembly. Stem thread rolled and hard plated - provides additional strength and maximum service life Mirror finish stem, burnished to 16 RMS - extends packing life and smooth stem operation Adjustable packing below stem threads - prevents stem lubrication washout and isolate threads from process contamination. Safety back seating - provides secondary stem seal in full open position, prevents stem blow out. Body to bonnet seal - metal to metal constant compression isolates bonnet threads from system fluids. Repairable Metal Seat - can be resurfaced without removing valve from line. MATERIAL OF CONSTRUCTION Sr No. Part Qty.
