Reliable control in
demanding environments
Swagelok has expanded its medium-
and high-pressure range with the
addition of IPT series products. The
series includes precision valves, fittings
and fluid control devices suitable
for surface and subsea installation,
instrumentation, injection and sampling
systems.
Products in the IPT series are made
standard from cold worked 316 stainless
steel. Annealed 316 stainless steel and
other corrosion-resistant special alloys
are available to meet NACE MR0175/
ISO 15156 requirements. Products
from the IPT series medium- and high-
pressure range are detailed below.
Preventing reverse flow where leak-tight
shutoff is required, IPT series check
valves are available in ball seat poppet,
soft seat poppet, and dual seal ball
styles to meet most applications.
Check valves are available with
maximum working pressures up to
60,000 psig (4,136 bar).
IPT trunnion ball valves accommodate
applications up to 20,000 psig (1,378
bar) and are available in sizes up to 1".
The valves are available with electric or
pneumatic actuators and accessories
for remote operation.
IPT series relief valves also have a
maximum working pressure to up
to 20,000 psig (1,378 bar), and are
available in
3
/
8
" to
3
/
4
" pipe ends.
Needle valves in the IPT series are
available in six body styles for a wide
range of applications. They are designed
to prevent galling and scoring with a
two-piece, non-rotating stem tip, and
a packing gland locking mechanism
prevents accidental disassembly. Needle
valves are available with maximum
working pressures up to 60,000 psig
(4,136 bar).
IPT series medium- and high-pressure
tubing and nipples are seamless,
austenitic and cold-drawn, and are
tested and inspected to meet maximum
strength and performance. Medium-
pressure tubing is available in

pressures of 60,000 psig (4,136 bar).
Medium-pressure coned and thread
connections from the IPT range provide
dependable performance and allow
for maximum working pressures up
to 20,000 psig (1,378 bar). The high-
pressure equivalents accommodate
working pressures up to 60,000 psig
(4,136 bar).
The range is complemented by
coning and threading kits that contain
everything required to prepare medium-
and high-pressure tubing in
