Needle Valves

Needle valves for instrument lines and fine throttling: stainless steel female-female and male-female bodies, angled and tube type versions, and Dk-Lok high pressure and autoclave valves. They are used to isolate a gauge or transmitter, to bleed and vent a line, and to damp a pulsating reading, not as bulk isolating valves on a process line. Give the connection type and size — thread or tube outside diameter — the working pressure, and the body and packing material to suit the medium and its temperature.
