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.
