OVERVIEW

Reliable High Purity Gas Delivery

When your work demands the absolute best in gas regulation, the Miller Smith 223-00-08 Silverline Regulator delivers. Known for their legendary quality, Miller Smith (formerly Smith Equipment) has designed the 220 Silverline series to bridge the gap between industrial durability and laboratory precision. This regulator is perfect for welders and fabricators who also manage calibration gases or specialized high-purity oxygen applications where standard industrial regulators fall short on precision and cleanliness.

Built for Consistency

Stop fighting with fluctuating pressures. The two-stage design of the 223-00-08 guarantees a steady flow from the moment you crack the cylinder until it's time for a swap. Unlike single-stage regulators that allow delivery pressure to creep up as the tank empties, this unit maintains a rock-solid output. This is critical for applications requiring exact flow rates for long durations. The large, 2-1/2 inch gauges are easy to read at a glance, ensuring you can monitor your supply and output levels with confidence.

Superior Materials and Protection

This isn't just a delicate lab instrument; it's built with a rugged brass bar stock body that can handle the real world. The entire body, bonnet, and gauge cases are plated to resist corrosion and keep the unit looking professional for years. Inside, a stainless steel diaphragm provides the sensitivity needed for fine adjustments while offering superior longevity compared to neoprene alternatives. The regulator also features a filtered seat to keep debris out of the sealing mechanism, preventing leaks and creep. Whether you are running a flame ionization detector or simply need the cleanest possible oxygen stream for a critical process, the Miller Smith 223-00-08 is the professional's choice.

FAQ

A two-stage regulator provides constant delivery pressure regardless of fluctuations in the cylinder pressure. As the cylinder empties, a single-stage regulator's output pressure can rise (decay), whereas a two-stage regulator compensates for this, providing a stable flow from full to empty.

The CGA 540 connection is the standard fitting for Oxygen and certain inert gas mixtures in industrial and high-purity applications.

A stainless steel diaphragm is used to prevent contamination. Unlike rubber or neoprene diaphragms, stainless steel does not outgas or absorb impurities, making it essential for high-purity analytical applications.

No, this regulator is recommended for high purity, non-corrosive pure gases and mixtures. It has a brass body which is not suitable for corrosive service.

The Miller Smith 223-00-08 is rated for a maximum inlet pressure of 3500 PSI.

Yes, the design allows the regulator to withstand vacuums generated during purging operations without damaging the internal components.

This specific model is calibrated for a delivery pressure range of 0-150 PSI.

Yes, it features a built-in capturable preset safety relief valve that automatically reseats to protect the regulator components from over-pressurization.
