Compact ball valve handles
heavy-duty applications
As first shut-off valve or for connecting
pressure measuring instruments,
the new model BV ball valve (photo) is
suitable for a variety of applications. It
is available in process and instrument
versions. The instrumentation valve is
compact and can therefore also be
integrated in space-restricted environments,
such as a control panel. Thanks
to its robustness, the model BV is suitable
for heavy-duty applications and
processes with critical media. Its pressurized
parts correspond to the safety
factor 4:1, its leak tightness has been
tested in accordance with BS 6755 /
ISO 5208, leakage rate A. An antistatic
design, a blow-out-proof valve spindle
and self-relieving valve seats ensure
the safe operation of the ball valve. -

New members added to this
line of valves
This company's line of air-piloted
valves now includes the APVS Media
Separated Valve Series (photo). This
new series is comprised of four different
styles of APVS valves and
provides many versatile options for
handling caustic media, all while
allowing safe operation in volatile
areas. The series includes inert gas/
spring-operated valves to control
high-purity, aggressive and corrosive
liquid chemicals while allowing
a flowrate superior to other similar
valves on the market. Each APVS
Valve can be configured to meet
critical user requirements with ordering
options that include various port
sizes, diaphragm seal materials, pilot
options and valve function. In addition,
an optional magnetic piston is
available for end-of-stroke position
sensing and can be combined with a
magnetic position sensor to maintain
positive feedback. - Spartan Scientific,

Still Fight Friction
We Designed It Out
Up to 6 Million Cycles
Unlike other valves that seal
with friction, Posi-flate's
unique butterfly valve uses
an inflatable seat to seal
with air pressure. Thus
it requires less torque and
a smaller actuator, resulting
in lower cost. Plus, the seat
automatically compensates for
wear, providing longer life.
Some users have reported
over 6 million cycles and the
valves are still going strong.
* Less Friction
* Low Torque
* Low Maintenance
* Longer Valve Life
