Ball Valves Clause Samples
Ball Valves. All ball valves will have full-area ports, Teflon seats and seals, and chrome-plated carbon steel or stainless steel balls. Ball valves bodies 2 inches and smaller will have threaded or socket weld end connections. Ball valves 2-1/2 inches and larger will have flanged or butt weld ends. The valves will not require lubrication. The use of these valves will be in accordance with the pressure temperature ratings specified by the manufacturer. Diaphragm Valves Diaphragm valves will be straight-away or ▇▇▇▇ bodies with flanged ends faced and drilled for installation between ANSI flanges. The use of these valves will be in accordance with the pressure temperature ratings specified by the manufacturer. Polyvinyl Chloride (PVC) and Chlorinated Polyvinyl Chloride (CPVC) Valves PVC and CPVC valves will be constructed entirely from polyvinyl chloride, chlorinated polyvi-nyl chloride, and Teflon. Bodies will be double-entry flanged or true union screwed type. The use of these valves will be in accordance with the pressure temperature ratings specified by the manufacturer. -------------------------------------------------------------------------------- Proprietary Information Page 33 AES IRONWOOD CONTRACT FINAL ISSUE - OCTOBER 30, 1998 -------------------------------------------------------------------------------- 2x1 501G REFERENCE PLANT APPLICATION HANDBOOK -------------------------------------------------------------------------------- MECHANICAL ENGINEERING DESIGN CRITERIA -------------------------------------------------------------------------------- Valve Materials Valve bodies will generally be constructed of materials equivalent to the pipe with which they are used. Valve body and trim materials of construction will be in accordance with applicable ASTM and AISI standards. The main cycle system valves will be free of copper materials to allow the cycle to be treated at the optimum pH for corrosion protection of carbon steel components. Valve Operators Valves will be provided with manual or automatic operators, as required, for the service application and system control philosophy. Automatic operators will be motor, piston, or diaphragm type. Manual operators will be lever, handwheel, or gear type, with the use of lever operators to be limited to valves requiring a maximum of 90-degree stem rotation from full open to full closed position on valve sizes 6 inches and smaller. All operators will be sized to operate the valve with the valve exposed to maximum diff...
