210-4010 - Miller Smith 210 Series High Purity Regulator CGA 590

High-Performance Gas Regulation

When precision cannot be compromised, the Miller Smith 210-40-10 Silverline Regulator stands out as a top-tier solution for high-purity gas control. While Miller is renowned for heavy-duty welding equipment, their Smith Equipment division brings that same level of reliability to analytical and specialty gas equipment. This single-stage regulator is specifically designed for applications requiring stable, low-pressure delivery (0-15 PSIG) of non-corrosive gases. Whether you are setting up a test bench, a biological lab, or an emissions testing station, the 210 Series delivers consistent performance you can trust.

Built for Durability and Purity

The "Silverline" designation is more than just a name; it represents a commitment to quality construction. The regulator features a plated brass body and bonnet, ensuring it withstands the rigors of daily use while resisting external corrosion. Inside, a stainless steel diaphragm takes center stage. This component is essential for precise pressure control and ensures that the gas stream remains uncontaminated by the regulator itself. The metal diaphragm eliminates the "off-gassing" associated with elastomeric diaphragms, making it suitable for high-purity analytical work. The filtered seat design further protects the internal components, ensuring a long operational life even in demanding environments.

User-Friendly Design

Miller Smith has designed the 210-40-10 with the operator in mind. The large 2-1/2 inch gauges are clear and easy to read, reducing the risk of reading errors. The regulator is also designed to handle the vacuum conditions often created during system purging, ensuring that your gas lines remain free of atmospheric contaminants before use. The CGA 590 inlet connection is precision-machined for a secure, leak-free fit with compatible cylinders. With a max inlet rating of 3500 PSIG, this regulator is ready for high-pressure supply tanks while delivering the low-pressure output required for sensitive downstream equipment. Trust Miller Smith for equipment that combines industrial durability with laboratory precision.
