OVERVIEW

Reliable Gas Delivery for Liquid Cylinders

The Miller Smith 252-20-02 Silverline Regulator sets the standard for reliability and performance in the management of gas withdrawal from liquid cylinders. Built on the legacy of Smith Equipment's quality engineering, this single-stage regulator is part of the esteemed 250 Silverline Series, known for its rugged construction and precision. It is specifically configured with a back-mount (rear entry) CGA 320 connection, making it the ideal solution for direct attachment to liquid carbon dioxide cylinders found in welding shops, laboratories, and bulk gas distribution facilities.

Rugged Construction for Industrial Use

Durability is key when dealing with industrial gas equipment. The 252-20-02 is constructed from solid brass bar stock, ensuring it can withstand the physical rigors of daily use. To further enhance its longevity, the exterior features a high-quality nickel plating. This plating serves a dual purpose: it gives the regulator a professional, clean appearance and, more importantly, provides superior resistance to corrosion and chemical attack. Whether installed in a clean lab environment or a busy workshop, this regulator is built to maintain its integrity and performance over the long haul.

Precision Pressure Regulation

Accurate pressure control is achieved through the use of a substantial 1-7/8 inch stainless steel diaphragm. In applications involving liquid cylinders, the gas can sometimes be cooler than ambient temperature. Stainless steel is the material of choice here because it does not suffer from the embrittlement or elasticity changes that affect rubber diaphragms. This results in a stable delivery pressure of 0-100 PSI, regardless of minor fluctuations in inlet pressure or temperature. The regulator is rated for a maximum inlet pressure of 3500 PSI, providing a wide safety margin for various cylinder conditions.

Maintenance and Longevity

Miller Smith has integrated their proprietary Sure-Seat™ filtered seat into this model. This advanced seat assembly filters out debris before it can damage the sealing surface, a common issue that leads to regulator creep. By protecting the seat, the regulator maintains a tight seal for longer periods, reducing the total cost of ownership. Combined with the easy-to-read 2-1/2 inch gauges and a precise needle valve outlet, the 252-20-02 offers a complete, high-performance package for any professional requiring dependable CO2 gas regulation from liquid sources.

FAQ

The Miller Smith 252-20-02 is rated for a maximum inlet pressure of 3500 PSI.

This regulator features a CGA 320 inlet connection, which is the standard fitting for Carbon Dioxide (CO2) cylinders.

No, this regulator is designed for gas withdrawal only. It connects to the gas use valve of a liquid cylinder to regulate the pressure of the gas phase.

The stainless steel diaphragm provides superior sensitivity and precision, and it is resistant to the low temperatures often encountered with cryogenic gas sources, ensuring a longer service life compared to rubber diaphragms.

The regulator provides a delivery pressure range of 0-100 PSI.

Yes, it includes a built-in capturable preset safety relief valve to protect against over-pressurization.

The rear-entry (back mount) design is specifically engineered for liquid cylinders, allowing the regulator to mount directly and cleanly to the tank valve without obstructing the gauges.

Sure-Seat is a filtered seat design that prevents contamination from entering the seating area, reducing wear and the need for repairs.
