Universal Flow Monitors (Hazel Park, MI) now
offers a HART protocol option on all of its variable area
and piston style flowmeters designed to perform in
challenging lubrication environments. The meters are
optimized for specific lubrication fluids. Features include:
n An optional mechanical switch to back up the
n Two adjustable set points.
n Availability in 12 sizes up to 2,000 psi pressure for
flow ranging up to 500 GPM.
n CSA and CE certifications.
High Airflow Vent for Extreme Weather
W. L. Gore & Associates (Elkton, MD) has announced its
next-generation PolyVent High Airflow, which advances the
performance capabilities of GORE Protective Vents Screw-In
Series. Engineered to handle the large pressure differentials
caused by extreme weather conditions, the new GORE
PolyVent High Airflow provides twice the airflow, with the
same ingress protection as Gore’s prior generation of “HA”
(High Airflow) vents. Features include:
n An improved O-ring that is UL-rated for flammability
n An advanced level of protection for enclosures up to 50 L.
n A throughput of 4,000 mL/minute at 70 mbar pressure
n Compliance with IP66, IP67, IP68 (1-hour immersion at 2
m), and IP69k (high-pressure steam) protection standards.
n A specially-treated membrane that provides oleophobic as
well as hydrophobic resistance.
Drop-In Hydraulic Cartridge Valves
HydraForce (Lincolnshire, IL) has announced a line of
‘drop-in’ style cartridge valves that draws less current
while generating greater actuator force to create faster
response for hydraulic applications. The valves are called
G3, because they represent the third generation of drop-in
valves developed by HydraForce. Features include:
n Model SV on/off solenoid valves.
n Model EHPR direct-acting proportional pressure
n Model TS pilot-operated proportional pressure reducing/
n Flow rates from 1 to 8 gal/min ( 4 to 30 L/min) at
operating pressures of 450-650 (20-45 bar), depending
on the model.
Miniature Pinch Valves
Clippard Instrument Laboratory (Cincinnati, OH)
has announced the Clippard NPV Series Miniature
Pinch Valve, a solenoid-operated device that is
designed to open and close tubes for controlling the
flow of liquids and gases. Features include:
n Four sizes with multiple pressure range options to
n 18” wire leads.
n A power consumption from 1.0 to 7. 2 W.
n The ability to handle whole blood and particulate
n An unobstructed flow path.
n 12” of medical/laboratory grade silicone tubing,
pre-installed with each valve.
n A variety of tubing sizes.
n A voltage of 12 or 24 VDC.
n A response time from 5 to 25 ms.
