Complete valves are available in straight through or 90º 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 ten turns from closed to full open.
The non-rising stem precision control valve (CVP) is available in six
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. |
