SAE flanges
SCHWER Fittings supplies a wide range
of SAE flange combinations in various
sizes. All items are available in standard
series 3000 PSI / ISO 6162-1 (SAE J518
Code 61) and in the heavy series 6000
PSI / ISO 6162-2 (SAE J518 Code 62).
Schwer stocks the flanges in both
stainless steel AISI 316TI and carbon
steel zinc plated chrome VI free. As
standard, the flanges are supplied with
FKM seals 85/90 shore for stainless
steel and NBR seals 90 shore for steel.
Counter flanges are standard without
O-Ring and with female threads. The
flanges are forged and of high tensile
strength. SAE flanges are used in areas
where strong vibration, high pressure
peaks and mechanical stress occur, in
industries such as offshore, shipbuilding,
hydraulic, petrochemical and paper
machines.
Schwer Fittings SAE flanges with
welding ends are offered as butt weld
or socket weld.

NEW, robust, clean break, low pressure
couplings in the CT series by Walther-
Präzision are designed for multi-purpose
use in chemical and fluid technology,
hydraulics, machine and systems
engineering, process engineering as
well as medical and food applications.
Manufactured fromtop-qualitymaterials
(stainless steel), the CT series is suited
to aggressive and toxic substances,
in the pressure range from vacuum to
64 bar.
The clean break technology of the CT
series enables the user to connect and
disconnect the non-drip, non-squirting
coupling safely and quickly, optimising
environmental and user safety.
Further characteristic features are mini-
mal pressure drops and high flow rates
due to a flow-enhanced design. Power
loss caused by friction is minimised
and the energy demand is reduced.
Clean break, low pressure couplings
Quick connection and separation times
require only low coupling forces, with
a safe and simple one-hand operation
through the integrated automatic lock.
The coupling can be safely connected
even under residual pressure.
“The way we planned the CT series,
the coupling can even be used for
demanding applications without any
modifications,” explained Dipl-Ing
Dirk Heinrich, head of development at
Walther-Präzision. “We even developed
and successfully introduced an
advanced thermal insulation for the CT
series that protects the user and we
also developed a purpose-built valve
technology for special applications, eg
for high temperature applications.”
The clean break couplings are
manufactured as standard from stainless
steel and come with an ATEX approval.
With its nominal sizes 5, 7, 9, 12 and
19mm, the new series complements the
company’s range of couplers, whose
larger nominal sizes cover 25 to 100mm.
