PRESSURE CONTAINING FASTENERS (continued)
FLANGED:
Installation of Flowserve flanged valves is best accomplished
by locating valves in pipeline flanges, assuring all corrosion and
foreign materials are removed from pipe flanges and then center
gaskets with the valve flanges. Fasteners or taper pins should
be used to align holes and locate gaskets. Fasteners should be
tightened to the corresponding valve and fastener size.
