Miniature proportional
valve for high flow and
low power
The Precision Fluidics division of Parker
Hannifin has announced the release of
its VSO® Max HP miniature high flow
proportional valve. This latest innovation
combines delivery of high flow rates with
25 per cent less power consumption
than comparable miniature proportional
valves.
VSO Max HP provides flows greater than
200 SLPM at 3.10 bar, while consuming
less than 2 watts of power, making it
suitable for medical applications that
require pressure and volume control,
such as ventilators, insufflators and
anesthesia delivery machines. As the
reduction in size of medical devices
without compromising on reliability
becomes paramount, VSO Max HP has
been engineered to deliver an operating
pressure of up to 8.27 bar, which
eliminates the need
for an inlet regula-
tor. This allows for
a smaller medical
device design that
offers optimum
results, and the
consistent flow
performance of the VSOMax HP delivers
reliability throughout the product life.
REACH and RoHS compliant, cleaned
for oxygen service use and with proven
performance up to 25 million life cycles,
the VSO proportional valve family
has been recognised in life sciences
applications for over a decade.

Air valve
sizing
software
Val-Matic’s Air Valve Sizing Program
is a web-based software program
designed to aid in selecting air valves
along a pipeline. Users are able to
enter and save design information
specific to their pump, water pipeline
or wastewater force main, to calculate
the locations and sizes of AWWA air
valves.
The program will also calculate the
collapse pressure, slope and gravity
flow in the pipe.
Recommendations are given for air valve
locations, sizes and model numbers for
pipeline and pump discharge locations.
