 * Electro-hydraulic
* Precise control of rotary valves
Rotary actuator. With closed loop position feedback, this actuator offers
precise control of rotary motion in applications such as gate valves and fly-by-wire
steering systems as well as articulation control in large vehicles. Its high frequency
response enables controlled motion at high speeds through a 45-degree range. Minimum input
produces zero motion, 50% input results in 50% of motion, and 100% input produces full
stroke. The unit responds to a variety of input commands such as 0-5 or 0-10 VDC, a
command potentiometer or remote joystick. Featuring a high frequency response of 10 Hz and
a torque of 1,000 ft.-lbs, the unit is suited for the harsh environment of mobile
equipment applications. Microhydraulics Inc, Mississauga, ON, Canada.

 Ball valve system. The Type 265X system is
designed to offer a variety of customized temperature, pressure, level and flow control
solutions. These valves feature high reliability, as well as low installation and
operating costs for both on/off and continuous/proportional controlled applications. The
system is available as a standalone on/off unit with single or double actuation, or as a
complete continuous process control valve system. Burkert Contromatic Corp,
Irvine, CA. Free Info--Circle 643.

 Miniature air cylinders Short stroke pneumatic
cylinders, with pistons keyed against rotation for applications requiring controlled
angular orientation of the translating motion operate on plant air in single acting,
spring return mode. Mack Corporation, Flagstaff, AZ. Free info--Circle

 Pressure regulating valves. The Hydra-Cell
valves have flow-through design for reduced wear on internal parts. They may be used with
any positive displacement pump. These valves bypass system fluid to prevent excess system
pressure for multiple-gun operations. Wanner Engineerin, Inc, Minneapolis,
MN. Free Info--Circle 645. http://www.OneRS.net/101df-645
 Customization process. The Quick-Change
Customization process adapts the technology and performance of standard, off-the-shelf
miniature valves into customized solutions that meet specific design, performance, and
application objectives. This fast track, low-budget process minimizes component design
time and performance risks. Components, such as connectors and port threads can be
customized. Bio-Chem Valve Inc, Boonton, NJ. Free Info--Circle 646. http://www.OneRS.net/101df-646
 Double solenoid proportional valve. The
economical DSP valve is designed for precision applications requiring flow-rates up to 800
gpm. Using OBE to monitor spool position, this valve does not sacrifice safety for high
dynamics. Bosch Automation Technology, Racine, WI. Free info--Circle 647.

 Luer check valves. This Quick-Stop valve allows
solvent change in an HPLC system, while preventing dangerous spills, and provides a means
for introducing samples into FIA and other low-pressure systems. The check valve allows
flow in either direction. Upchurch Scientific, Oak Harbor, WA. Free

 Low-flow valve. The VSOLF is an addition to the
current line of VSO valves offering enhanced flow control for those low-flow applications
where controllability is critical or expected below 600 sccm. The VSO is a miniature
solenoid-operated proportional valve featuring the ability for fine control of very low
flows. Applications include gas analyzers, electronic pressure controllers and mass
spectrometers. Parker Hannifin Corp, Hollis, NH. Free Info--Circle 649.
