220-4010 - Miller Smith Silverline 220 Series High Purity Regulator CGA 590

Industrial Grade High Purity Regulation

For professionals requiring exacting standards in gas regulation, the Miller Smith 220-40-10 Silverline Regulator delivers unmatched performance. While often found in laboratories, this high-purity two-stage regulator is built with the rugged durability expected from Miller Smith industrial equipment. It is specifically configured with a CGA 590 inlet connection, making it suitable for industrial air and specific specialty gas mixtures requiring precise low-pressure delivery up to 15 PSI.

Rugged Construction

Durability does not take a backseat to precision in the Silverline series. The regulator is machined from solid brass bar stock, ensuring it can withstand the physical demands of industrial environments. To further enhance its longevity, the entire body, bonnet, and gauge housings are plated. This plating acts as a shield against environmental corrosion and scratches, keeping the tool in prime condition even after years of service. The large, 2-1/2 inch single scale gauges are easy to read at a glance, allowing operators to monitor cylinder and delivery pressure efficiently.

Consistent Performance

The two-stage architecture of the 220-40-10 is critical for applications where pressure drift cannot be tolerated. In standard single-stage regulators, delivery pressure can rise as the cylinder pressure falls—a phenomenon known as the supply pressure effect. This unit eliminates that variable, providing a steady flow of gas at your set pressure (0-15 PSIG) throughout the life of the cylinder. This reliability is essential for calibration mixtures and carrier gases where consistency is key to process integrity.

Advanced Features

Equipped with a stainless steel diaphragm, this regulator offers precise control sensitivity that elastomeric diaphragms cannot match. The metal diaphragm also ensures that the regulator remains leak-tight and does not contaminate the gas stream. The unit includes a 1/4" FNPT needle valve on the outlet, allowing for fine flow adjustments directly at the regulator. Whether you are setting up a calibration station or managing sensitive industrial processes, the Miller Smith 220-40-10 provides the control and reliability you need.
