OVERVIEW

Reliable Gas Delivery for Critical Applications

When your welding or industrial process requires absolute consistency, the Miller Smith 623-83-09-00-00 Silverline Regulator delivers. While standard regulators may fluctuate as your tank drains, this premium two-stage regulator maintains a rock-steady output pressure of up to 250 PSI. This is critical for specialized TIG welding applications, laser systems, or any process using inert gases like Argon, Nitrogen, or Helium where flow consistency directly impacts quality.

Built by Miller Smith, a name synonymous with quality in the gas equipment industry, this regulator is constructed from solid brass bar stock and finished with a durable nickel plating. This not only gives it a professional appearance but also provides superior resistance to corrosion and physical damage compared to standard forged bodies. The large 2-1/2 inch single scale gauges are easy to read, allowing operators to monitor tank levels and delivery pressure at a glance.

The Silverline series stands out with its focus on purity and safety. The stainless steel diaphragm offers a precise response to pressure changes and eliminates the "creep" often associated with rubber diaphragms. Additionally, the bonnet features threaded ports for venting, adding an extra layer of safety for facility integration. Whether you are setting up a high-precision weld station or managing gas distribution for manufacturing equipment, this regulator provides the reliability and performance professionals demand.

FAQ

A two-stage regulator reduces the cylinder pressure in two steps, which allows it to maintain a constant delivery pressure even as the pressure in the supply cylinder drops. This eliminates the need for frequent readjustment.

CGA 580 is the standard connection for inert gases such as Argon, Nitrogen, and Helium. It is not compatible with flammable or oxidizing gases.

Stainless steel diaphragms do not absorb or release contaminants (off-gassing) like rubber or neoprene diaphragms can. This ensures the gas stream remains pure for sensitive analytical or process applications.

This regulator is rated for a maximum inlet pressure of 3500 PSI, making it compatible with high-pressure cylinders.

No, the Miller Smith 620 Silverline series is designed for non-corrosive gases. The brass body construction is not suitable for corrosive media.

Yes, the regulator features threaded front and rear bonnets that facilitate panel mounting for fixed installations.

This specific model (623-83-09-00-00) has a delivery pressure range of 0-250 PSI.

The capturable vent (1/16" FNPT) allows you to pipe any vented gas away from the immediate area, which is a critical safety feature when working in confined spaces or with specific facility safety requirements.
