GU Series needle valves in general utility service

The Swagelok Company extends its product portfolio with the GU series needle valves for use in general utility service applications

Swagelok Company extends its product portfolio with the GU series needle valves for use in general utility service applications.

The new GU series needle valves isolate and vent system media in instrument air, nitrogen header, lube oil, and other general utility applications, mainly in the oil and gas, chemical and petrochemical markets.

Offered in stainless (for salt water usage) and carbon steel, the GU series valve can be ordered in straight and angle patterns with a choice of end connections in sizes from 0.25 to 1 inch (6 to 25 mm).

The valve features operating pressures up to 6000 psig at 200F (413 bar at 93C).

A sour gas service model is also available.

A two-piece knuckle joint drives the hardened stem tip to create a leak-tight seal.

The non-rotating stem design minimises seal wear, protects the seat from galling, and helps promote long service life.

Located above the valve packing, 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.
