Valve Bodies of DN100, DN150 & DN200
valves are equipped with studs and Valve
Covers are secured by Hex Nuts and Hex
Bolts.
V-Ring is attached to Diaphragm of DN100,
DN150 & DN200 valves at factory. If, during
internal valve inspection, V-Ring is
discovered to be detached from Diaphragm,
be advised that V-Ring is a required valve
component and that detachment will not
affect normal valve operation or
performance. Should V-Ring become
detached, reinstall between Diaphragm
and Diaphragm Cover concentrically as
shown.
NR - Not Replaceable
CH - Common Hardware
NOTE: Do not apply adhesives, lubricants,
or other substances to Diaphragm, V-Ring,
or Valve Body.
