involved in this section necessary for completion of the work, as shown on the Contract Plans, <br /> as specified in the Standard Specifications, these special provisions and as directed by the <br /> Engineer, shall be considered as included in the prices paid for the various contract items of <br /> work involved and no additional compensation will be allowed. <br /> PART 2 — PRODUCTS <br /> 2.01 GENERAL <br /> Valves shall be furnishec full line size unless specifically called out to be of reduced size. <br /> Unless otherwise specified, valves shall be rated for 150 psi working pressure minimum. <br /> All valves shall be complete with all necessary operating hand wheels, chain wheels, extension <br /> stems, valve boxes, floor stands, worm and gear operators, operating nuts, chains, hardware <br /> and fasteners, and wrenches which are required for the proper completion of the work included <br /> under this section. Operating torque to operate any valve shall not exceed 40 ft-Ib. Unless <br /> otherwise indicated, the direction of rotation of the wheel, wrench nut or lever to open the valve <br /> shall be counterclockwise. Each valve body or operator shall have cast thereon the word <br /> "OPEN" and an arrow indicating the direction to open. Actual length of valves shall be within <br /> 1/16 inch (plus or minus) Df the specified or catalog length except where installed adjacent to <br /> flexible or mechanical pipe couplings, where different lengths of a replacement can be <br /> accommodated. Flanges shall meet the requirements of ANSI B16. <br /> Valve boxes and extended stems to within 24 inches of finished grade shall be provided for all <br /> buried valves. <br /> Materials of like kind shall be the product of one manufacturer. <br /> 2.02 MANUAL ACTUATORS <br /> All valves, except those which are equipped with power actuators or are designed for automatic <br /> operations, shall be provided with manual actuators. Unless otherwise specified or indicated on <br /> the Drawings, each manual actuator shall be equipped with an operating hand wheel. Manual <br /> operators for butterfly valves shall be designed in accordance with AWWA C504 and shall have <br /> a disc position indicator designating the opened and closed position of the valve. <br /> Operators for butterfly valves six-inches in diameter and smaller shall be level actuators and <br /> permit locking the valves in at least five intermediate positions between fully open and fully <br /> closed. Operators for butterfly valves eight-inches in diameter and larger shall be the traveling <br /> nut type. Manual operators for plug valves shall be totally enclosed, worn gear type. Manual <br /> operators for exposed service valves shall include a handwheel and be of the traveling nut, rack <br /> and pinion, or worm gear type and be gasketed for weatherproof service. Operators shall be <br /> equipped with adjustable mechanical stop-limiting devices to prevent over-travel of the disc in <br /> the open and closed positions and shall be self-locking and designed to hold the valve in any <br /> intermediate position between full open and full closed. Handwheel shall require less than 40 lbs <br /> force to achieve the necessary operation torque. Valve operator components shall withstand an <br /> input torque of 300 ft-lbs at the extreme operator positions without damage. <br /> Operators for buried service shall be provided with a two-inch square operating nut unless <br /> otherwise specified or shown. Operating extension stems shall be provided to bring the <br /> July 2007 Division III-162 NEI Phase II Water and Sewer <br /> CIP Nos. 7468, 7589, 7590 <br />
