The rollers assist the travel of the gate assembly along tracks set into the valve body, retaining it in alignment, and pro- moting ease of operation, not otherwise possible. Scrapers are provided ahead of the rollers to clear the track of obstruction or foreign matter. When required, rollers, tracks and scrapers are bronze. Valve Installed horizonfolly in o CLOW AWWA DOUBLE DISC GATE VALVES IRON BODY, BRONZE MOUNTED, PARALLEL SEAT CLOW VALVE COMPANY Description and Advantages CLOW AWWA Gate Valves are designed primarily for flow con- trol of water in underground pipe lines. They equal or exceed the requirements established by standards of the American Water Works Association and conform to Federal Specifications WW- V-58B, Type II, Class I. CLOW AWWA Gate Valves are specifically designed for heavy pressure service. Neck, flanges, and bell are made extra heavy to withstand pipe strain and possible shifting. Body, cover, gates, and stem are built for extra strength, wi(h clean and sim- ple internal construction, to assure long service and low main- tenance, Operation of the Valve Turning the stem releases the wedging pressure on the gates allowing them to move away form their seats before starting upward travel. Further turning of the stem raises the gates into the fully opened position. When closing the valve, the gates move freely downward with- out friction, to a position opposite their seats. As the gates approach the bottom of the valve, the iron hooks come into contact with stops which prevent further sownward movement of the hooks. The bronze wedges riding on these hooks spread the gates apart and force them against their seats. Construction Body: Cast iron, bronze mounted. Sturdy proportions provide protection against damage. Stem: Manganese bronze of high tensile an.d torsional strength, with accurate, perfectly machined threads. Ample diameters assure smooth valve movements. Stem Nut: Solid bronze. Independent of hooks, gates, and wedges. Stem or stem nut will not bind or spring out of line, as can happen when stem nut is attached to wedges. Wedges: Independent, solid bronze, 2' - 3' valves have integral hook and wedge. 4' - 8' have independent solid bronze wedges placed loosely in iron hooks, and are free to adjust to varying positions of the gates. In 10' and larger valves, each wedge has one long and one short surface. The bottom of each wedge Iorms a rocker bearing on the iron hooks, letting wedges adjust to varying positions ot the gates in closing. The long side is used in closing the valve and the short side in opening it. Low Torque Thrust Bearing: Valves 4'. 12' are fitted below the stem collar with an exclusive Low Torque Thrust Bearing which . provides high load capacity and low friction. This bearing reduces operating torque up to 50% yet seals pedectly for repacking under pressure. Gates and Gate Rings: Gates 3' and smaller are bronze. Gates 4" and larger are high strength cast iron with bronze gate rings rolled into machined and dovetailed grooves under pressure to make gate and ring one inseparable unit. After fitting, gate rings are accurately machined. Case Rings. Bronze case rings are screwed into place and machined. They can be removed and replaced if necessary. Packing: O-Ring packing is standard on all non-rising stem gate valves. Rising stem and geared valves are furnished with con- ventional packing. Operating Nut and Handwheel: All valves except fianged valves and outside screw and yoke valves are supplied with 2" square operating nuts of high strength cast iron unless otherwise spec- ified. Flanged vanes and outside screw and yoke valves are supplied with handwheels of high strength c~st iron unless oth- erwise specified, Direction of opening is indicated by arrow cast on operating nut skin or on the rim of the handwheel. Yoke: Yokes for outside screw and yoke valves are of rugged cast iron. Careful machining assures accurate stem alignment. Accessories: Valves may be fitted with any large number or accessories: cylinders, electric motor operators, gearing, by- passes, etc. Rollers, Tracks and Scrapers: Recommended for 14" and larger diameter valves carW weight of the gates for valves installed in a horizontal line in a vertical line. NOTE: All valves open to the left (counter clockwise) unless oth- erarise specified.
