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.
