310-83000000 - Miller Smith 310 Series Silverline High Purity Stainless Steel Regulator, 0-25 PSIG

Technical Overview of the Miller Smith 310 Series Silverline Regulator

The Miller Smith 310-83-00-00-00 is a premium single-stage regulator engineered specifically for high-purity, corrosive, and toxic gas applications. Part of the Silverline series, this unit is meticulously constructed from 316 stainless steel bar stock, ensuring minimal contamination and exceptional resistance to chemical attack. The regulator features a 316 PCTFE (Polychlorotrifluoroethylene) seat, which is critical for maintaining integrity in corrosive environments where standard elastomers would fail. This material choice, combined with a 316 stainless steel filtered seat, significantly extends the service life of the component while preserving the purity of the gas stream.

Precision pressure control is achieved through a specially designed convoluted stainless steel diaphragm. Unlike flat diaphragms, the convoluted design offers superior sensitivity and response to pressure changes, allowing for stable regulation even at low delivery pressures. The diaphragm utilizes a metal-to-metal seal with the body, eliminating the need for O-rings in the sensing element and thereby maximizing leak integrity—a non-negotiable requirement for toxic or high-purity systems. The regulator is rated for a maximum inlet pressure of 3500 PSIG and delivers a precise outlet pressure range of 0-25 PSIG.

Safety and integration are key aspects of the 310 Series design. The bonnet includes a captured vent port (1/16" FNPT), allowing operators to pipe vented gases away to a safe disposal area in the event of a diaphragm failure. This feature is essential when handling hazardous media. The unit is also designed for versatility in installation, featuring a threaded bonnet for front panel mounting and a tapped body for rear panel mounting. The inlet and outlet connections are 1/4" FNPT, providing compatibility with a wide range of standard high-purity fittings and piping systems.
