Body: Newco cast Steel bodies provide low resistance flow and optimum strength and Yoke & Bonnet : Newco Bonnet assemblies are built to the same standards as the bodies. Larger size gate Valves utilize a multi-piece Bonnet Grease Fitting: The grease fitting allows for easy stem Stem: The stem is precision machined and inserts into the horizontal channel in the Wedge: Newmans 1-piece flex wedge is machined to the tightest tolerances to ensure trouble free shutoff and Back Seat Bushing: The back seat, when engaged with the stem head, provides a stable shutoff to the stuffing box which isolates the packing from flow Gland: Compresses the packing to create a stem seal above the back seat, between the Bonnet and Gland Flange: Applies pressure to the gland for accurate packing & 10.

2 Gland Bolts & Nuts: The gland bolt and nut allows for easy adjustments for packing Gland Bolt Pin: The gland bolt pin secures the gland bolts to the yoke & Packing: The packing creates a seal above the back seat, between the Bonnet and Stuffing Box: The stuffing box contains the Stem Nut: The stem nut provides a precision guide for proper stem Yoke Bushing: The retaining nut secures the stem nut to the Bonnet Handwheel: The handwheel cycles the Handwheel Nut: The handwheel nut secures the handwheel to the Bonnet Set Screw: The set screw prevents handwheel nut Bonnet Gasket: The Bonnet gasket creates a leakproof seal between the Bonnet and & 21. Bonnet Studs & Nuts: The Bonnet studs and nuts secure the Bonnet to the Seat Rings: To ensure a stable shutoff, seat rings are aligned and seal-welded into the valve, then precision ground for optimal Spacer Ring: Assists the packing rings in creating a seal above the back seat, between the Bonnet and Free: 3 Newco cast Carbon Steel Bolted Bonnet ValvesProduct Line Technical DataRev: Steel Bolted Bonnet GatesStyles: CB2, CB3, & CB4/2 Class 150 - Sizes: 2 thru 48 Pressure Class Range: 150 thru 1500 Note: Dimensions: Inches/Millimeters - Weights: Pounds/Kilograms.
