Sluice valve shall conform to IS 14846 (ISI Marked). Except pump house, these valves

are to be installed in valve chamber. All valves of pump house and rising mains shall

be non-rising stem type.

The valves shall be free from sharp projections, which are likely to catch and hold

stringy materials. Valves shall close with clockwise rotation of the hand wheel. The

direction of closing and opening shall be marked on the hand wheel.

Necessary joining materials viz. bolts, nuts, washers, packing etc. shall be provided

by the contractor at his cost. The valves shall be fixed so as to have axis perfectly

horizontal. If required the contractor shall also carry out drilling of holes of

appropriate diameter in flanges in required numbers. A hand wheel shall be provided

for emergency operation. The hand wheel drive shall be mechanically independent.

The valve design shall take care of the pressure drop across the valve disc in case of

partial opening of the valve and shall take care of the erosion and cavitation effect

on the body and disc during such operation. Valve(s) subjected to back pressure shall

have the valve seat, disc and the operator suitably designed to ensure trouble-free

operation. The shaft diameter shall take into consideration, the maximum torque

required for the valve operation, the maximum differential pressure across the valve

disc when the valve is closed and the shock load due to accidental closure of the

valve disc. The disc shall be designed for maximum differential pressure across the

valve as well as the shock load due to accidental closure of the valve. Disc design

shall offer minimum head loss. Disc shall also offer minimum resistance to flow Disc

shape shall be contoured.

Valve seats shall be of a design that permits removal and replacement at site and

shall be securely clamped on the body or disc of the valve. Seat material shall be

suitable for the operating conditions and handling fluid and may be suitably

reinforced, if required. The seat design shall permit easy removal for replacement

purposes without the need for removing the valve from the line. No deposited or

shall not have any harmful effect due to handling fluid. Adjustable thrust bearing(s)

shall be provided to hold the valve disc securely in the center of the valve seat. Each

Sluice Valve shall be provided with a hand wheel for manual operation. For the

Valves located at inaccessible position, it shall be provided with extension spindle

and floor stand or hand lever / round chain to facilitate manual operation.

Hydrostatic Test

Each valve body shall be subjected to hydrostatic test (Body and Seat) as per IS

14846. For valves subjected to back pressure condition, leakage test shall be carried

out on both sides of the disc.

Performance Test

Each valve complete with operator shall be shop operated at least three (3) times

from fully closed to fully open conditions and reverse, hold at intermediate positions

under no flow condition, to prove the workability of the assembly.

Positive material Identification (PMI Test)

PMI test shall be checked at random for Stainless steel parts.

Test Certificates

When specified by Owner, the manufacturer shall issue a test certificate confirming

that the valves have been tested in accordance with this standard and stating the

actual pressures and medium used in the test.

Marking shall be cast integral on the body or on a plate securely attached to the body

for ‘DN’ size, ‘PN’ rating, Heat Number and Serial number.

Each valve shall be drained, cleaned, prepared and suitable protected with 2 coats of

red oxide and then black bituminous paint for minimum of 150 micron DFT on

surfaces before dispatch.

Electric Actuator

Each actuator shall be adequately sized to suit the application and be continuously

rated to suit the modulating control required. The gearbox shall be oil or grease

filled, and capable of installation in any position. All operating spindles, gears and

head stocks shall be provided with adequate points for lubrication. The valve

actuator shall be capable of producing not less than 1½ times the required valve

torque and shall be suitable for at least 15 minutes continuous operation.

Volume-III, PRICE BID VKV RWSS

The actuator starters shall be integrally housed with the actuator in robustly

constructed and totally enclosed weatherproof housing. The motor starter shall be

capable of starting the motor under the most severe conditions. The starter housing

shall be fitted with contacts and terminals for power supply, remote control and

remote positional indication, and shall also be fitted with internal heaters so as to

provide protection against damage due to condensation.

ITEM NO. 15 Refiling the pipe line trenches incl. ramming watering, consolidating,

disposal of surplus stuff as directed with in a radious of 3.00kms

On completion of the pipe laying operations in any section, for a length of about

100m and while further work is still in progress, refilling of trenches shall be

started by the Contractor with a view of restricting the length of open trenches.

Pipe laying shall closely follow the progress of Trench Excavation and the

Contractor shall not permit unreasonably excessive lengths of trench excavation

to remain open while awaiting testing of the pipeline. If the Engineer considers

that the Contractor is not complying with any of the foregoing requirements, he

may prohibit further trench excavation until he is satisfied with the progress of

laying and testing of pipes and refilling of trenches. The excavated material

nearest to the trench shall be used filling. Care shall be taken during backfilling,

not to injure or disturb the pipes, joints or coating. Filling shall be carried out

simultaneously on both sides of the pipes so that unequal pressure does not

occur. Walking or working on the completed pipeline unless the trench has been

filled to height of at least 30cm over the top of the pipe except as may be

necessary for tamping etc., during backfilling work.

The remaining portion of the trench may be filled in with a mixture of hard and

soft material free from boulders and clods of earth larger than 150mm in size if

sufficient quantity of good earth and murrum are not available. The trench shall

be refilled so as to build up to the original ground level, keeping due allowance

for subsequent settlement likely to take place. The top 300mm layer or fertile

agricultural soil shall be kept aside during excavation and shall be laid in layers

near ground level during refilling.

To prevent buckling of pipe shell of diameters 1200mm and above, pipes shall be

strutted from inside while the work of refilling is in progress, for which no

separate payment shall be made.

Strutting shall be done by means of strong spiders having at least 6 arms which

shall be sufficiently stiff to resist all deformation. Spiders shall be provided at a

maximum interval of 2m & shall be welded in such a way that internal coating

does not get burnt.

The Engineer shall, at all times, have powers to decide which portion of the

excavated materials shall be for filling and in which portion of the site and in

what manner it shall be so used.

If any material remains as surplus it shall be disposed of as directed by the

Engineer, which includes loading, unloading, transporting and spreading as

directed within all lead. If the Contractor fails to remove the earth from site

within 7 days after the period specified in a written notice, the Engineer may

arrange to carry out such work at the Contractor's risk and cost or may impose

Volume-III, PRICE BID VKV RWSS

such fine for such omission as he may deem fit. Particular care shall be taken to

keep the trench dry during the entire refilling operation.

If suitable material for refilling is not available for excavation the Contractor

shall bring earth, murrum of approved quality as directed by the Engineer.

No mechanical plant other than approved compacting equipment shall run over or

operate within the trench until backfilling has reached its final level or the

approval of the Engineer has been obtained.

Subsidence in filling in : Should any subsidence take place either in the filling of

the trenches or near about it during the maintenance period of 24 months from

the completion of the Contract Works, the Contractor shall make good the same

at his own cost or the Engineer may without notice to the Contractor, make good

the same in any way and with any material that he may think proper, at the

expense of the Contractor. The Engineer may also, if he anticipates occurrence

of any subsidence, employ persons to give him timely notice of the necessity of

making good the same, and the expenses on this account shall be charged to the

Payment shall be as per payment schedule
