Design
왘
When isolation of the process from an
nstrument is required, Ashcroft
i
®
ffers a
o
comprehensive line of diaphragm seals.
Seal types include threaded, flanged,
in-line threaded, in-line flanged, in-line
socket weld, in-line butt weld, saddle
and sanitary seals. Also available is a
complete offering of isolation or iso-rings
and isolation or iso-spools.
APPLICATIONS
• Elevated process temperatures
• Corrosive service
• Isolation of the process for safety
• Suspended solids in the process
• Sanitary connections
• Minimize process dead leg
• Ease of cleaning between batches
FEATURES
• The top housing and diaphragm capsule
are interchangeable with all Ashcroft
bottom housings.
• A fill/bleed connection is standard, which
permits filling the seal and instrument
simultaneously after evacuation and allows
the fill to flow into the completed unit.
• A Viton O-ring, compatible with all stan-
dard fill fluids, and a Teflon back-up ring
provide a seal between the diaphragm
capsule and the top housing.
• A thin Teflon PTFE gasket between the
diaphragm and bottom housing ensures
a leak-tight corrosion resistant seal even
at high pressure.
• Top housing and pressure instrument are
removable.
• Continuous-duty design will prevent loss
of process fluid if pressure instrument is
removed or fails.
