NEEDLE VALVES

Swagelok(r) offers Needle Valves, GU Series. It finds applications in oil and gas, chemical, petrochemical, and other general industrial markets. It is offered in stainless and carbon steel. It is available in straight and angle patterns with a choice of end connections in sizes from 1/4 to 1 inch (6 to 25 mm). The valve features operating pressures up to 6000 PSIg at 200°F (413 bar at 93°C). A two-piece knuckle joint drives the hardened stem tip to create a leak-tight seal. The non-rotating stem design minimizes seal wear, protects the seat from galling and offers long service life. Both the knuckle joint and the strong, cold-rolled stem threads are isolated from system media and protected from dust and dirt by a stainless steel shroud. It is also used for research, instrumentation, pharmaceutical and semiconductor industries.
