121-4102 - Miller Smith Silverline 2-Stage CO2 Regulator, 0-60 PSI, CGA 320

Precision Two-Stage Control for CO2 Applications

The Miller Smith 121-41-02 Silverline Series Regulator is a premium gas control device engineered for applications requiring unwavering delivery pressure. As a two-stage regulator, it reduces cylinder pressure in two distinct steps. This mechanical advantage allows the regulator to maintain a constant output pressure of 0-60 PSIG, even as the inlet pressure from the CO2 cylinder decays significantly during use. This feature is critical for laboratory settings, calibration benches, and precision manufacturing where pressure drift cannot be tolerated.

Constructed from rugged brass bar stock, the body and bonnet are plated to resist corrosion and maintain a professional appearance over years of service. The internal mechanism features a large 1-7/8 inch diaphragm, which provides superior sensitivity to low-pressure adjustments compared to smaller compact regulators. The unit is equipped with Miller's proprietary Sure-Seat technology, which incorporates a filtered seat to trap particulate matter before it can damage the sealing surface, ensuring gas stream purity and extending the service life of the component.

This specific configuration (121-41-02) comes ready for Carbon Dioxide service with a CGA 320 inlet connection. It also features a specialized outlet setup, including a 1/8-inch tube fitting and a brass needle valve, allowing for fine-tuned flow control directly at the regulator. Whether used for inert gas blanketing or analytical work, the Silverline series delivers the reliability professionals demand.
