| Key
Instruments offers control valves for low
flow OEM, laboratory instrumentation, or
bench top flow control applications. The
valve designs and material make them suitable
for use with a variety of gases and fluids.
Complete valves are
available in straight through or 90 degree
angle body configurations and are constructed
of brass or stainless steel. All valves
are supplied with 1/8" FNPT inlet and
outlet ports. The valve cartridge may also
be integrally mounted in flowmeter assemblies.
The economical cartridge valve (CVS) is
available in three different needle tapers
which cover our entire flow range. These
units have a rising stem and provide nine
turns from closed to full open.
The precision control
valve (CVP) features a non-rising stem and
is available in eight different needle tapers,
for fine control of very low flows. This
valve offers sixteen turns from closed to
full open. Its design eliminates saw-toothing
and is virtually hysteresis free. All materials
are matched for similar coefficients of
expansion. |
