46-50 - Smith Series 46 Heavy Duty LP Gas Station Regulator 0-50 PSIG

Smith Series 46 Heavy-Duty LP Gas Station Regulator

The Smith Equipment 46-50 is a premium single-stage station regulator designed specifically for heavy-duty industrial applications using LP gas (Propane). Part of the renowned Series 46 line, this regulator is engineered to be installed at station drops on pipeline or manifold systems where the inlet pressure does not exceed 100 PSIG. Unlike cylinder regulators that handle high tank pressures, this unit provides precise downstream control for fabrication stations, ensuring that torches and heating equipment receive a stable and consistent flow of fuel gas.

At the heart of the 46-50 is a large stainless steel diaphragm. This material choice is critical for industrial environments as it resists corrosion, prevents leaking, and eliminates the freeze-up issues often associated with elastomeric diaphragms in cold conditions or high-flow scenarios. The stainless steel construction ensures that the regulator maintains accurate pressure settings over a long service life, providing a delivery range of 0-50 PSIG which is ideal for most cutting, heating, and brazing operations.

Maintenance and longevity are further enhanced by Smith's exclusive Sure-Seat filtered high-pressure seat assembly. Gas distribution systems can often carry particulate matter that damages regulator seats, leading to creep or failure. The Sure-Seat design incorporates a filter that traps these contaminants before they reach the seating area, drastically reducing repair costs and unplanned downtime. This feature makes the Series 46 a favorite among maintenance managers who require reliability in continuous production environments.

Durability is evident in every external component as well. The regulator features a nickel-plated bonnet and a solid brass body, offering excellent resistance to shop corrosion and wear. The 2.5-inch polished brass gauges are equipped with shatter-resistant polycarbonate lenses, ensuring they remain readable even after accidental impacts. An external relief valve is standard, providing a critical safety layer by automatically venting excessive pressure in the event of a surge, protecting both the equipment and the operator.
