OMEGA
control valves for low flow OEM,
laboratory instrumentation, or bench
top flow control purposes. The valve
designs and material make them
suitable for use with a variety of
gases and fluids.
Complete valves are available in
straight through (180°) or 90° angle
body configurations and are
constructed of brass or stainless
steel. All valves are supplied with
1
⁄8" FNPT inlet and outlet ports. The
standard control valve is available in
3 different needle tapers which
cover our entire flow range. These
units have a rising stem and provide
10 turns from closed to full open.
The non-rising stem precision
control valve is available in 6
different needle tapers, for fine
control of very low flows. This valve
offers 16 turns from closed to full
open. Its design eliminates sawtoothing and is virtually hysteresisfree. All materials are matched for
similar coefficients of expansion.
