Specials shall be excluded and measured and paid separatelyunder the relevant item.8.27.2 The portion of the pipes at the joints (inside the joints) shall not be included inthe length of pipe work.8.27.3 Excavation, refilling, masonry and concrete work wherever required shall bemeasured and paid for separately under relevant items of work.8.28 RatesThe rate shall include the cast of the material and labour involve in all theoperation describe in the item.8.29 Zero Velocity Valves8.29.1 Construction:8.29.1.1 Body: The Spring Loaded self-actuating Zero Velocity valve has an outerfabricated casing ('Main Body') in which a 'Central Rod' is held by struts. Inorder to create an annular flow the included angle of the cone at upstream ofthe disc should be 50-60° and the cone at downstream of the cone should be20-30°. The barrel at inlet and outlet of the valve should suit the pipe diameter.The barrels should have minimum length of 250 mm to 500 mm based on thesize of valve for the ease of installation.Urban Administration & Development Department Page 100
8.29.1.2 The total length of the valve should be as per the table below:Diameter (mm)Total length ofvalve (mm)500 1850550 1850600 1920650 1950700 2000750 2100800 2300850 2300900 2150950 23001000 2400Dim Tol +/- 15 mm max8.29.1.3 The valve should be provided with 2 to 4 (four) Nos. of hand holes of adequatesize to facilitate insertion and removal of springs by hand (if required) withoutremoving the valve from line. A suitable cover shall be provided on each of thehand hole.8.29.1.4 A 'Bypass pipe' with a Valve of 80 NB for 500 - 650 mm, 100 NB for 700 950mm and 150 NB for 1000 mm and above should be provided for connectingupstream and downstream sides of Zero Velocity valve should be provided.Minimum two plugs should be provided to mount Pressure gauges at theupstream and downstream of the valve.8.29.1.5 Adequate transportation support should be provided on the valve as an integralpart of the valve.8.29.1.6 Internal: Closing Disc is mounted on 'Central Rod' cladded with Stainless Steel(SS as per AISI304) for the adequate length so that the disc moves on thecladded portion. Bush of the disc should be lined securely with Brass sleeve(minimum 3 mm thick) for smooth sliding of the disc.8.29.1.7 Disc is held in closed position by a adequate number of 'Stainless SteelSprings' (SS as per AISI304). The anti-rotation guides should be provided onthe edge of 'Central Disc' with minimum resistance to flow and minimumpossibility to lock during sliding of the disc. The 'Anti Rotation Guide' should becladded with Stainless Steel Strip (SS as per AISI304) and 'Guide Fork' linedwith brass liners. The valve should be provided with a 'Stationary CentralDome' to create an annular streamlined passage for smooth flow of water.8.29.1.8 Painting: 2 (Two) coats of Coal tar Epoxy Paint from inside and outside.Material of Construction of principal parts:S.
