1.0 GENERAL

Tamper proof / Bi stream air valves shall having one outlet of large capacity for admission and
release of bulk volume of air during emptying and filling of the main and another having small
outlet for escape of smaller quantities of entrapped air. This type of air valves shall be of flanged
type with full conformation with IS:1538.

The ball sealed orifice always remains open while air is exhausting and is immediately closed
when water rises in the chamber, lift the ball and seals the orifice. It shall also ensure that there
are no recesses or pockets, sheltering, escaping air for the large orifice (low pressure) valve to
drop into when the valve is open. Turbulent air at the time of filling of pipe shall not circulate in
such cavities and cause the ball to blown into when the valve is open. Turbulent air at the time of
filling of pipe shall not circulate in such cavities and cause the ball blown into the discharging air
streams, blowing the valve shut prematurely.

The cone angle of the lower pressure chamber shall be such that even at the critical velocity of
air escape at 300 m/sec. The total impact force on the ebonite covered ball is less than the suction
force on the angular area between the ball and the cone. The design of the valve should be such
as to allow maximum free air discharge at various pressure differentials. The tenderer shall
submit with the tender full set of curves showing discharge of free set of curves showing
discharge of free air valves pressure differential for all sizes of valves offered by him.

Under no circumstances shall be large orifice ball blow shut prematurely.

The low pressure cover shall be massive and designed to withstand full operating thrust in
working conditions.

Air valve shall be design to prevent premature closure prior to all air having been discharge from
the line. The orifice shall be positively sealed in the close position but flot ( Ball) shall only be
rised by the liquid and not by mixer of air and liquid. The sealing shall be design to prevent the
flots sricking after long period in the close position.

All branched outlets including outlets for Air valves will be with compensation pads (Dia of
Main / For branch Dia ratio greater than 3). Diameter of compensation pad will not be less than
1.75 times thr O.D. of the branched outlet. Plate thickness for pads will be same that of the main.

For outlets with above ratio less than three, then the joints will be of plate reinforcement type.

All branched outlets including air valve tee’s will be provided with one ½”BSP coupling duly
plugged for measurement of pressure in due course. The closing plug will be in Stainless Steel
(AISI 304 or equivalent) with Hex. Head and will be provided with copper washer for sealing.

59
 The neoprene seat ring shall be held securely in place under the low pressure cover by a joint
support ring to prevent it from sagging when the ball is not sealing the office.

The valve body, the orifice cover, cowl of the air valves shall be made of cast iron of glade 2 of
IS:210.

Where tenderer considers necessary a suitable drain plug shall be provided.

2.0 HIGH PRESSURE ORIFICE

The high pressure orifice and the high pressure chamber shall be so designed that the orifice is
effectively sealed in working conditions by “EPDM” coated float.

The material of the orifice shall be gunmetal. The orifice shall be of size not less than 3 mm and
tapering to 100 mm suitable to release accumulated air within the pipe. The profile of the orifice
shall be carefully chosen to avoid damage to the float surface. The orifice shall be protected by a
suitable plug of stainless steel.

3.0 VALVE FLANGES

All valves flanges shall be designed to withstand the stresses to which they would be subjected
under hydraulic tests. Flanges shall be machined flat. The flanges shall be drilled in accordance
with IS:1538 (part – I to XXII) – 1976 (specifications for C. I. Fittings for pressure pipes for
water etc.)
4.0 COATING

The casting shall be such that it shall not impart any taste or smell to water. The coating shall be
smooth, glossy and tenacious, sufficiently hard so as not to flow when posed to a temperature of
770 C and not so brittle at a temperature of 150 C as to chip off when scratched lightly with the
point of penknife.
Alternatively, two coats of black Japan conforming to type 8 of IS 341-1971 (Or latest edition) or
paint conforming to type – 2 of IS 158-1969 (OR latest edition) shall be applied.

5.0 TAMPER PROOF / Bi Stream AIR RELEASE VALVES
