311-66250000 - Miller Smith 310 Series Silverline SS Regulator, CGA 660, 0-50 PSIG

Miller Smith 311-66-25-00-00 Silverline High Purity Regulator

The Miller Smith 311-66-25-00-00 Silverline High Purity Regulator is a premium single-stage pressure control device engineered specifically for the rigorous demands of specialty gas delivery. Designed to handle corrosive, non-corrosive, and toxic gases, this regulator is a critical component for analytical laboratories, industrial processes, and high-purity applications where contamination control is paramount. The unit is constructed almost entirely from 316 stainless steel, including the body, filtered seat, and diaphragm, ensuring exceptional resistance to corrosion and maintaining the purity of the gas stream.

One of the standout technical features of the 310 Silverline series is the convoluted stainless steel diaphragm. Unlike standard flat diaphragms, this convoluted design provides superior sensitivity and accuracy, allowing for precise regulation of delivery pressure even as cylinder pressure decays. The metal-to-metal diaphragm seal eliminates the need for elastomeric seals in the gas path, thereby maximizing leak integrity—a crucial safety factor when handling hazardous media. The regulator is rated for a maximum inlet pressure of 3500 PSIG and provides a stable delivery pressure range of 0-50 PSIG.

Safety and versatility are built into the design. The bonnet features a captured vent port (1/16" FNPT), which allows users to pipe vented gases away to a safe location in the unlikely event of a diaphragm failure. This is essential for maintaining a safe working environment when working with toxic or flammable gases. Additionally, the regulator includes a stainless steel needle valve on the outlet for fine flow control. The unit is designed for flexibility in installation, with a threaded bonnet for front panel mounting and a tapped body for rear panel mounting. With its CGA 660 connection, this specific model is tailored for cylinders containing corrosive gases such as Chlorine or Ammonia mixtures.
