Miller Smith Silverline 220 Series High Purity Two-Stage Regulator, 0-100 PSI, 1/4 FNPT

Reliable High Purity Gas Delivery

For industrial and laboratory professionals requiring exacting standards, the Miller Smith 222-40-00 Silverline Regulator delivers unmatched reliability. This high-purity, two-stage regulator is built to handle the demands of specialty gas delivery with a maximum inlet pressure of 3500 PSI and a precise delivery range of up to 100 PSI. It is the ideal choice for applications requiring constant delivery pressure, such as calibration mixtures and carrier gases.

Built for Performance

The Silverline 220 Series is distinguished by its robust construction and thoughtful engineering. The regulator body is machined from brass bar stock and finished with a high-quality plating that protects the body, bonnet, and gauges from corrosion and wear. This ensures the tool remains accurate and functional even in demanding work environments. The unit is equipped with 1/4" FNPT inlet and outlet connections, allowing for versatile plumbing configurations to suit specific manifold or cylinder setups.

Two-Stage Consistency

One of the primary advantages of the 222-40-00 is its two-stage regulation mechanism. In critical applications, a drop in delivery pressure as the supply tank empties can ruin a process or invalidate a test. This two-stage regulator eliminates that variable, providing a steady flow and pressure from the moment the tank is opened until it is depleted. Combined with a stainless steel diaphragm that ensures precise control, this regulator removes the guesswork from gas delivery.

Key Features

• High Purity Design: Stainless steel diaphragm and filtered seat maintain gas integrity.
• Easy Monitoring: Large 2-1/2" single scale gauges provide clear readings.
• Safety First: Includes an automatic reseating safety relief valve to protect against over-pressurization.
• Versatile Use: Capable of withstanding vacuum purging, making it suitable for complex gas systems.
