Hand chain : Has been detailed elsewhere in this document. Bearings : Has been detailed elsewhere in this document. Valves & Specials for Pump individual delivery & common header/manifold piping : Has been detailed elsewhere in this document.
Butterfly valve for individual pump discharge branch and common header. The Butterfly valves shall be CSDF ling wafer type, P.N., conforming to IS:13095. The seat pressure shall be 25kg/cm 2 and the body pressure shall be 30kg/cm 2 . The valve shall operate smoothly and steadily in both directions, free from flow induced vibrations. It shall provide tight shut off closure and shall be suitable for frequent operations as well as for throttled duty condition. The valve disc should rotate 90 from full open to full close position. The valve disc shall be solid stream lined slab design and to have minimum head loss. The seal ring shall be replaceable type and to be bolted on the body. The rubber seal on the disc must be of easy replaceable type with the facility of replacement at site. The valve of both individual pump branch and common header shall be CIDF and of suitable dia. subject to minimum 200mm. and 300mm. respectively for individual pump branch and common header. Operational arrangement of the Butterfly valves shall be with motorized actuator with inbuilt gear box and providing with extended spindle with suitable yoke so as to operate the same by the operator standing at ground / floor level. Non-return Valves. The N. R. valves shall be of suitable dia. (minimum 200mm.), CSDF, single door, suing check type which shall be provided with each individual pump discharge line. The body pressure shall be of 30kg/cm 2 and seat pressure shall be of 25kg/cm 2 . The Non-return valves shall have ample thickness and the disc shall be of non slam type. The disc of the valves properly weigh balanced to prevent pump against the valve body while in operation. The valves should pass through a hydrostatic test for minimum 30 minutes duration.
