MOUNTING/INSTALLATION PROCEDURE
:
1.
ENSURE THAT:
a)
While storing, keep the valve in cool, dry, dust free area.
b)
On receipt of the valve, in case if the same is to be removed from the sealed plastic bag for
inspection/testing, put them back with dust plugs on its ports and sealing the plastic bag as soon as the
inspection/testing is over.
c)
The valve should be removed from its card board and/or plastic bag just before the installation.
d)
Flush lines before installing the valve.
e)
To avoid pressure drop and to achieve optimum parameters, Pipe / Tube / Fitting from the source of
pressure to the valve and to the connected equipment should have ID which is
NW (Orifice) of the
valve.
f)
To avoid pressure drop, if more than one valve is being operated simultaneously from a common
header, then minimum ID of the header can be calculated as under.
ID Header =
(NW
2
n)
n = Number of Valves operating at a time and which are connected to a common header,
NW = Orifice of the Valve.
g)
Incorporate filter in the line to avoid hard particles entering into the valve.
h)
Do not try to drill any additional holes or machine, modify any of the valve components.
i)
Inlet pressure does not exceed rated pressure.
j)
Hemp-
Filaments, ’Jute’ or even Teflon-Ribbons are normally not required, as the port connections of
ROTEX Valve is accurately machined.
k)
Do not cover first two thread pitches with Teflon tape or sealant. To avoid over lap of the Teflon ribbon or
cuts generated while tightening, getting carried away into the valve.
