high torque or harsh climate
conditions. Using this tool,
an operator can easily drive
multiple valves, and it is designed
to prevent both the application
of excessive torque
and torque kickback, thereby
reducing operator fatigue and
the risk of injury. This device
is adaptable to any type or
size of valves, and provides a
low-cost alternative to permanent
actuators with no permaof
standard and specialty materials,
and options include bypass,
air or motor actuators. - Conval,

Positioner provides fast response
for large valves
This control-valve positioner package
(photo) ensures precise positioning
with fast response times
over the entire operating range, for
applications with strokes of 60 mm
or greater. The package consists of a
positioner and a connection to several
volume boosters with different
air-output capacities. Closing and
opening times of less than two seconds
can be achieved over the entire
positioning range. This device
is especially useful for compress or
bypass valves (anti-surge valves).

Ball valves help users meet
lead-elimination requirements
The Pro-Press family of lead-free
ball valves, available in sizes from
0.5 to 2 in. and made from a proprietary
silicon-bronze alloy, is specifically
designed for press systems.
Multiple configurations and multiple
thread or connector options are
available. The valve stem is available
in Eco Brass or Type 316 stainless
steel. - Viega, Wichita, Kan.

Portable valve-actuator device
can service multiple valves
The EasiDrive portable valve actuator
is a versatile tool for use
with valves that require a large
number of turns or that are otherwise
difficult to operate because of
nent power supply required, says
the company. It is said to be ideal
for moving tight or partially seized
valves. - Smith Flow Control, Erlanger,
Ky.

Select or design the valve you
need for any fluid service
This firm offers a broad array of engineered
valves to manage hydraulic
fluid oil, air, refrigerants, water,
chemicals, fuel and gases in a variety
of industrial applications. Material
options include steel, stainless
steel, brass, aluminum and Monel,
and all forms of fittings are available.
Custom engineering and manufacturing
helps to reduce costs,
assembly time and potential leak
points. - Fluid Line Products, Willoughby,
Ohio

These digital valve controllers
can be mounted remotely
The Fieldvue DVC6200p series of
digital valve controllers are designed
for applications in which accessibility,
extreme temperatures
(up to 120°C or 250°F), extreme
vibration or confined space makes
integral mounting impractical.
With the remote-mount version of
DVC6200p, only the valve-position
feedback is mounted on the control
valve; the remainder of the digital
controller can be mounted more
than 300 ft away (in a preferable
environment). With no linkages to
wear, loosen or corrode, the feedback
unit can withstand extreme operating
conditions. - Emerson Process
Management, Marshalltown, Ia.
