the temperature rating of flanged end terminates at 538 deg. C.
FLOW DATA
Valve flow coeffient Cv defined as the flow of water at 60 deg F in
gallons per minute (GPM) at a pressure of one pound per square inch (1
psi) accross a value.
WHERE
Q
: Flow rate (GPM)
Cv : Flow coeffient
ΔP : Pressure drop (psi)
p : Density of fluid (p=62.4), water at 60 deg F)
THEREFORE

INSTALLATION CAUTIONS
- The valve is bi-directional and
can be mounted in any position. However, it is recommended that
the valve is horizontal to the stem and the inclined cone edge of
disc faces towards the downstream. ( Refer to directional arrows
and stem side )
- If you want to use at temperatures
below -48 deg C or above 426 deg C, the extension design shall be
applied. In such case please contact the sales department.
