and/or caution notes will appear and must be strictly adhered to,
otherwise, serious injury or equipment malfunction could result.
Baker Hughes has a highly skilled After Sales Department
available for start-up, maintenance and repair of our Masoneilan
valves and component parts.
Arrangements for this service can be made through your local
Baker Hughes Representative or After Sales Department. When
performing maintenance use only Masoneilan replacement
parts. Parts are obtainable through your local Baker Hughes
Representative or Spare Parts Department. When ordering
Masoneilan parts, always include Model and Serial Number of
the unit being repaired.
Baker Hughes valves can be used as control or shut off valves.
They are offered in a number of body styles and valve trims. The
type of duty will dictate the trim selected.
Always know what the valve has to do and specify it accordingly.
Important points to consider are: type of fluid, pressure,
temperature, thermal and mechanical pipe strains, hydraulic
tests, water hammer, thermal shocks, PED2014/68/EU (where
applicable), NACE MR0175, corrosion, environmental conditions
and valve orientation.
2. Description
These installation and maintenance instructions apply to all sizes
and ratings of the Masoneilan 33000 Series control valves.
The 33000 valve series is a Triple Offset Butterfly valve which
incorporates new performance enhancing operational features,
allowing for a more simplified manufacturing process. It offers
high capacity while providing excellent seat leakage performance
in both directions. The ability to quick removal and replacement
of the valve components during maintenance saves valuable
plant downtime.
