A 1700 series needle valve for fine flow control in instrument lines. It has a forged body and integral bonnet. A non-rotating hard stem tip or a replaceable PCTFE stem tip reduces galling, and Dyna-Pak packing below the stem threads prevents fugitive emissions. It is used in panel board instrumentation, pressure gauge valves, sampling systems, research laboratories, oxygen service, and corrosive or high-pressure service.
