122-4006 - Miller Smith Silverline 2-Stage Regulator, CGA 350, 0-100 PSI

Precise Control with Miller Smith Silverline Series

The Miller Smith 122-40-06 Silverline Series General Purpose Two Stage Regulator is engineered for applications requiring unwavering delivery pressure and high gas purity. As part of the renowned Silverline 120 Series, this regulator is designed to handle the rigors of general plant, maintenance shop, and laboratory environments. The unit features a specific CGA 350 connection, making it suitable for hydrogen and other compatible gas services, with a delivery pressure range of 0-100 PSI.

Advanced Two-Stage Design

Unlike single-stage regulators that allow delivery pressure to fluctuate as the supply cylinder drains, this two-stage model maintains a constant output pressure throughout the life of the cylinder. This is achieved by reducing the pressure in two steps: first from the high cylinder pressure to an intermediate stage, and then to the final delivery pressure. This design is critical for analytical work and precision applications where flow stability is paramount.

Robust Construction and Reliability

Built to last, the 122-40-06 features a rugged brass bar stock body and bonnet, finished with chrome plating for superior protection against corrosion and wear. The internal mechanism includes a large 1-7/8 inch diaphragm that provides exceptional sensitivity and precise control over the outlet pressure. Additionally, the regulator is equipped with Miller Smith's Sure-Seat technology, which incorporates a filtered seat to prevent debris from entering the seating area, thereby extending the service life of the regulator and ensuring gas stream purity.

Safety and Usability

Safety is a core component of the design, featuring a preset safety relief valve that vents to the atmosphere in the event of over-pressurization. The regulator also boasts large, 2-1/2 inch single-scale gauges that are easy to read, allowing operators to monitor cylinder and delivery pressure at a glance. The body is tapped for rear panel mounting, offering versatile installation options for various setups.
