120-0009 - Smith Silverline 2-Stage Nitrogen Regulator, 0-15 PSIG, CGA 580

Precise Inert Gas Control with Smith 120-0009

The Smith Equipment 120-0009 General Purpose Two-Stage Regulator is engineered for applications requiring unwavering pressure stability and precision. Designed specifically for inert non-corrosive gases such as Nitrogen, Argon, and Helium, this regulator features a CGA 580 inlet connection compatible with standard industrial gas cylinders. As a two-stage device, it excels in environments where maintaining a constant delivery pressure is critical, regardless of the fluctuating inlet pressure as the supply cylinder empties. This characteristic makes it an ideal choice for laboratory settings, purging applications, and industrial processes where consistency is key.

Constructed from rugged brass bar stock, the body and bonnet are plated for superior protection against corrosion and wear. The regulator utilizes a large 1-7/8 inch diaphragm which provides exceptional sensitivity and control, particularly important for the low 0-15 PSIG delivery range of this model. The inclusion of a filtered seat prevents debris from entering the seating area, significantly extending the service life of the unit and ensuring gas stream purity. For safety, a self-resetting relief valve is integrated to vent excess pressure to the atmosphere, protecting downstream equipment from over-pressurization.

Whether you are managing blanketing gases, performing leak tests, or supplying analytical instruments, the Smith 120-0009 offers the reliability professionals demand. Its 1/4" FNPT outlet allows for easy adaptation to various hose or piping configurations, making it a versatile addition to your gas management system.
