30-20-540 - Smith Equipment 30 Series Medium Duty Oxygen Regulator 0-20 PSIG CGA 540

Smith Equipment 30 Series Oxygen Regulator - 30-20-540

The Smith Equipment 30-20-540 is a premium medium-duty single-stage oxygen regulator engineered for industrial environments requiring precise low-pressure control. Part of the renowned 30 Series, this regulator is specifically calibrated for a delivery range of 0-20 PSIG, making it an essential component for specialized applications such as fine welding, brazing, and heating where standard 100+ PSI regulators lack the necessary sensitivity. The unit connects via a standard CGA 540 inlet and is rated for a maximum inlet pressure of 3000 PSIG.

Advanced Filtration and Durability

At the core of the 30-20-540 is Smith's exclusive Sure Seat™ filtered seat technology. This proprietary design incorporates a high-density filter that prevents microscopic debris and contamination from entering the high-pressure seating area. Seat failure due to contamination is the leading cause of regulator malfunction; by eliminating this variable, the Sure Seat™ system significantly extends the service life of the regulator, reduces maintenance downtime, and lowers long-term repair costs. The internal mechanism is further supported by a highly durable neoprene composite diaphragm that offers superior flexibility and response compared to standard stainless steel diaphragms in this pressure class.

Rugged Industrial Construction

Built to withstand the rigors of daily industrial use, the regulator features a rugged forged brass body paired with a bright nickel-plated bonnet. This combination not only provides structural integrity but also offers excellent resistance to corrosion and environmental wear. The unit is equipped with 2.0-inch corrosion-resistant polished brass gauges protected by shatter-resistant polycarbonate lenses, ensuring readability and safety even in harsh shop conditions. An external self-reseating relief valve is integrated into the design to protect the regulator and downstream equipment from inadvertent high-pressure surges, automatically resetting once safe pressure levels are restored.

Compliance and Warranty

Manufactured in the United States, the Smith 30-20-540 adheres to strict quality standards. It features color-coded labels for immediate gas service identification, enhancing safety in multi-gas environments. Smith Equipment backs this regulator with their True Blue™ 3-Year Limited Warranty, providing assurance of quality and performance for industrial users in aerospace, construction, and manufacturing sectors.
