Reliable High Purity Gas Management

For professionals requiring exacting standards in gas regulation, the Miller Smith 220-40-02 Silverline Regulator stands out as a premier choice. Part of the renowned Silverline 220 Series, this two-stage regulator is built to deliver consistent performance for high purity applications. It is particularly recommended for controlling carrier gases and calibration mixtures, ensuring that your operations run smoothly without the interference of pressure spikes or drops. The robust construction and thoughtful engineering make it a dependable asset for any facility handling specialty gases.

Built for Durability and Performance

Miller Smith has constructed this regulator with a focus on longevity and reliability. The body and bonnet are machined from brass bar stock and finished with high-quality plating. This not only gives the regulator a sleek, durable finish but also provides excellent resistance to external corrosion. Inside, a stainless steel diaphragm takes charge of pressure regulation, offering a level of precision and durability that rubber diaphragms cannot match. This metal diaphragm is essential for maintaining the purity of the gas stream, ensuring that no contaminants are introduced during the regulation process.

Consistent Delivery Pressure

One of the primary challenges in gas delivery is the fluctuation of outlet pressure as the supply cylinder empties. The 220-40-02 solves this with its two-stage architecture. By reducing pressure in two steps, it isolates the delivery pressure from changes in the inlet pressure. This means you can use virtually the entire contents of a cylinder without having to constantly adjust the regulator knob. With a delivery range of 30" HG vacuum up to 30 PSIG, it offers fine control for low-pressure applications.

User-Friendly Features

The regulator is equipped with a CGA 320 inlet connection, standard for Carbon Dioxide cylinders. It features large, clear 2-1/2 inch gauges that allow operators to monitor tank and delivery pressure easily. A filtered seat adds an extra layer of protection, preventing debris from damaging the internal sealing surfaces. Additionally, the automatic reseating safety relief valve provides peace of mind by preventing dangerous over-pressure situations. Trust the Miller Smith Silverline series for your critical high-purity gas regulation needs.
