Isolating Valves

If isolating valves are used they mount directly onto the site mounting flanges.

Air Purge

The purges mount onto the isolating valves. They are mounted by separating
the front flange from the air purge by unscrewing the four locking nuts. A 'snout'
and 'O' ring arrangement locate into the front flange; work the two apart
carefully. The front flange should now be bolted to the isolating valve if used or
site flanges with a rigid gasket fitted between them, using the four countersunk
screws provided.
WARNING!!!
The adjustable flange is then offered up to the front flange, taking care that the
'O' ring seal and 'snout' locate smoothly into the central aperture. This is then
re-secured by the four locking nuts that screw down onto the adjustable flange.
The arrangement should now appear as below:
