3.12 Installation steps for the flowtap flange socket version
with a safety chain
1. Completely depressurize and drain the pipe prior to installing the Deltatop.
2. Drill a hole with the diameter D1 into the pipe.
3. Tack-weld the mounting flange into position by using the appropriate weld gap (typically
1/16" (1.5 mm)).
!
Note!
The bolt holes of the flange must be at 45° angles (for four holes) or 22.5° angles (for eight
holes) to the pipe axis.

4. Bolt the access valve to the mounting flange using the gasket, studs and nuts provided.
5. Orient the valve such that the valve stem is parallel to the centerline of the pipe.
a. For horizontal pipes, orient the valve such that the valve stem is parallel to the centerline
of the pipe.
b. For vertical pipes, orient the valve such that the valve stem is perpendicular to the
centerline of the pipe.
