Steel alloy compressor valve
offers lower installed cost
Unlike its stainless-steel counterpart,
designated StraightFlo SS (severe
service), the new SE StraightFlo SE
(standard edition) reciprocating compressor
valve (photo) serves relatively
non-corrosive compressor applications
typically found in upstream and
midstream gas-compressor markets.
Gases encountered in these
applications include sweet and sour
natural gas, air, gas with natural gas
liquids, and industrial gases such as
oxygen, carbon dioxide, hydrogen,
helium and acetylene. The company
performed extensive development
and testing of material options,
settling on 4140 steel alloy for the
StraightFlo SE valve. This introduction
follows extended field trials in a
full range of upstream and midstream
applications. The SE valve has the
same ability to extend run times up
to 35 times and provide power savings
or throughput increases up to
15%, says the company. - Zahroof

Blower package for pneumatic
conveying systems
This company supplies a wide
range of positive displacement (PD)
continuous vacuum, pressure and
vacuum/pressure system blower
packages (photo) for conveying
bulk materials. Packages are available
for 2- to 10-in. conveying
systems. Each blower package includes
a silencer and is supported
on a heavy-duty base, allowing
easy access for cleaning. Built-in
braces permit the entire package
to be moved into position with a
forklift during installation or maintenance.
A heavy-duty drive guard
totally encloses the drive to protect
plant personnel. An expanded metal
front allows the operator to visually
inspect the belts without removing
the guard and lets the heat from the
belts dissipate for longer belt life.
Routine maintenance is simplified
by the drive guard's easy-access
design. Every blower package incorporates
an industry-proven
positive displacement blower. The
blower is dynamically balanced,
and isolation pads are positioned
between the blower and the base to
reduce vibration and noise. An industry-proven
motor that meets all
NEMA specifications is standard on
every package. Like the blower, the
motor is mounted on isolation pads
to reduce vibration. - Coperion KTron

This motor is thrice certified for
use in hazardous locations
The IEC Zone 2 & 22 and UL Div 2,
Class I & II, Triple-Certified motor
(photo) is designed to comply with
over 80% of global minimum energy
performance standards (MEPS) and
certificates, including North America
and Europe. The IEC motor is UL
and CE marked and complies with
the U.S. IHP (integral horsepower)
and E.U. EcoDesign requirements.
The Triple-Certified motor is specifically
designed to drive much of the
auxiliary equipment in the oil-andgas
industry and is suitable for luberication
pumps, heat exchangers
and blowers. These foot-mounted
motors have a cast-iron frame and
end plates, are inverter ready, and
have Class F insulation with Class
B temperature limits to ensure the
motor performs reliably in oil-andgas
applications. A six-post terminal
block in a large F3 (top mounted)
terminal box provides easier, lower
cost installation. Motors are IP66
to provide protection against harsh
environments. - ABB, Motion business,

Electric two-stage, horizontaltank
air compressors
This company offers a line of electric
two-stage, horizontal-tank stationary
air compressors (photo) that
are suitable for applications requiring
greater pressure. The line displaces
between 9.1 and 107.0 ft3/
min at 175 psi. The 22 belt-driven
models in this two-stage horizontaltank
line provide an extensive range
of size and power options. On the
