312-66250000 - Miller Smith 310 Silverline Stainless Steel Regulator, CGA 660, 100 PSIG

High-Purity Stainless Steel Regulation

The Miller Smith 312-66-25-00-00 Silverline Regulator is a premium single-stage gas control device engineered specifically for high-purity and corrosive gas applications. Part of the renowned 310 Silverline Series, this regulator is constructed from 316 stainless steel bar stock, ensuring that all wetted parts are resistant to chemical attack and corrosion. This material selection is critical for maintaining the integrity of the gas stream, preventing contamination that can occur with standard brass components.

Precision Diaphragm Technology

At the heart of this regulator is a convoluted stainless steel diaphragm. Unlike elastomeric diaphragms that can degrade or off-gas, this metal-to-metal seal provides a robust barrier against leakage, ensuring the highest level of system integrity. The convoluted design enhances the sensitivity of the regulator, allowing for precise control of delivery pressure even as cylinder pressure decays. This makes it an excellent choice for laboratory environments, analytical instrumentation, and semiconductor manufacturing where pressure stability is paramount.

Safety and Filtration

Safety is a primary design consideration for the 312-66-25-00-00. The unit features a captured vent port (1/16" FNPT) located in the bonnet. In the rare event of a diaphragm failure, this port allows hazardous or toxic gases to be piped away to a safe ventilation system, protecting personnel and the workspace. Additionally, a 316 stainless steel filtered seat is integrated into the design to trap particulates, extending the service life of the regulator and protecting downstream equipment from debris.

Versatile Installation

Designed for flexibility, the regulator supports both front and rear panel mounting. The bonnet is threaded for panel installation, while the body includes tapping for rear mounting configurations. Large, 2-1/2 inch single-scale gauges provide clear visibility of inlet and outlet pressures, ensuring operators can monitor system status with ease. With a maximum inlet pressure of 3500 PSIG and a delivery range of 0-100 PSIG, this regulator is a versatile solution for a wide range of specialty gas cylinders utilizing a CGA 660 connection.
