Installation
Pre-Installation Inspection
Inspect the piping system prior to valve installation whenever
possible, to ensure that it has been properly flushed and cleared of
construction and fabrication debris. The seating surfaces in soft
seated valves are particularly susceptible to weld slag and sand
blasting grit. Pipe scale, metal chips and other foreign materials
should be removed.
Just prior to installation, remove each valve from its packing and
remove any end covers. Examine the flow bore for debris. All Apollo
ball valves are shipped in the open position to prevent damage to the
ball surface. Any grit or foreign matter must be removed. Scratched
or dented balls must be replaced. Do not install a damaged valve.
Two piece threaded end Apollo Ball valves are bi-directional. They
may be installed in vertical or horizontal pipe runs without regard to
flow direction and without regard to stem orientation.
Note: Valves must be installed in piping systems that comply with the
applicable portions of the ASME B31 standards. Special
considerations must be taken with respect to pipe line expansions and
contractions and the media expansion and contractions within the
piping system.
Threaded End Valves
Pipe connections to be threaded into these valves should be
accurately threaded, clean and free of foreign material or metal
shavings. Apply pipe sealant compound or PTFE tape to the male
pipeline threads only. Do not use sealant on the female threads as
excess compound may be forced into the valve body. This could
cause sticking of the ball or encourage the accumulation of dirt and
