221-0008 - Miller Smith 220 Series Silverline High Purity Two-Stage Regulator CGA 540

Precision Control with Miller Smith 221-00-08 Silverline Regulator

For professionals demanding the highest standards in gas regulation, the Miller Smith 221-00-08 Silverline Regulator delivers unmatched performance and reliability. Part of the esteemed 220 Silverline Series, this two-stage regulator is built to handle high-purity applications with ease. Whether you are managing specialty gases for industrial processes or precise calibration mixtures, this regulator ensures that your delivery pressure remains constant, regardless of fluctuations in the supply cylinder.

The two-stage architecture of the 221-00-08 is a key advantage for consistent operations. By reducing pressure in two steps, it eliminates the "decay" effect common in single-stage models, where delivery pressure can rise as the cylinder pressure falls. This means you can set your pressure once and trust it to hold steady until the tank is ready for change-out. The unit is equipped with a CGA 540 connection, making it compatible with standard oxygen cylinders and other gas mixtures utilizing this fitting standard.

Durability is built into every component. The regulator features rugged brass bar stock construction that is fully plated—including the body, bonnet, and gauges—to resist corrosion and wear. The stainless steel diaphragm is a standout feature, offering superior sensitivity for pressure adjustments and ensuring that the regulator does not contaminate the gas stream. This makes it an excellent choice for applications where maintaining the chemical integrity of the gas is critical.

Safety and ease of use are also prioritized. The regulator includes a built-in capturable preset safety relief valve to prevent over-pressurization. The large 2-1/2 inch gauges are clear and easy to read, allowing for quick monitoring of both cylinder and delivery pressures. With a delivery range of 0-50 PSIG and a maximum inlet pressure of 3500 PSIG, the Miller Smith 221-00-08 is a versatile and dependable tool for high-precision gas regulation tasks.
