46-175 - Smith Series 46 Heavy Duty Oxygen Station Regulator, 0-175 PSIG, CGA 024

Smith Series 46 Heavy-Duty Oxygen Station Regulator Overview

The Smith Equipment 46-175 is a premium single-stage station regulator designed specifically for heavy-duty industrial applications where oxygen is supplied via a pipeline or manifold system. Unlike cylinder regulators, this unit is engineered to handle the lower inlet pressures typical of station drops (max 200 PSIG) while providing precise delivery control up to 175 PSIG. The regulator connects via a CGA 024 inlet, the standard for oxygen station valves, ensuring compatibility with professional shop infrastructure.

Engineered for Durability and Precision

At the core of the Series 46 is a large stainless steel diaphragm. Unlike rubber or neoprene diaphragms found in lesser units, stainless steel offers exceptional resistance to corrosion, leaking, and freeze-ups. This material choice ensures that the regulator maintains accurate pressure control over a significantly longer service life, even in fluctuating temperature conditions. The body is constructed from solid brass, complemented by a nickel-plated bonnet that adds an extra layer of corrosion resistance, making it suitable for harsh shop environments.

Exclusive Sure Seat™ Technology

One of the standout features of this regulator is Smith's proprietary Sure Seat filtered high-pressure seat assembly. Contamination is the leading cause of regulator failure; debris entering the seating area can cause creep or complete failure. The Sure Seat design incorporates dual filters to trap particles before they reach the critical seating surface. This innovation drastically reduces repair costs and downtime, ensuring reliable operation shift after shift.

Safety and Usability Features

Safety is paramount in high-pressure gas handling. The 46-175 includes an external relief valve that protects the regulator and downstream equipment from damage due to inadvertent high-pressure surges. If pressure exceeds safe limits, the valve releases the excess and automatically resets. For the operator, the regulator features large, 2.5-inch corrosion-resistant polished brass gauges with shatter-resistant polycarbonate lenses, making pressure readings clear and safe. A resin bonnet insert facilitates smooth, low-torque pressure adjustment, allowing for precise setting of the 0-175 PSIG delivery range.
