Smith Series 30 Two-Stage Oxygen Regulator - 35-125-540

The Smith Equipment 35-125-540 is a premium industrial-grade two-stage oxygen regulator designed for applications requiring precise and constant delivery pressure. Part of the renowned Series 30 (often referred to as Series 35 in specific configurations), this regulator is engineered to drop cylinder pressure to working pressure in two distinct stages. This mechanical advantage ensures that the outlet pressure and flow remain consistent regardless of fluctuations in the inlet pressure as the gas cylinder empties. For professionals engaged in precision oxy-fuel cutting, welding, or laboratory work, this feature eliminates the annoyance of "pressure creep" and the need to constantly readjust the torch flame.

Durability and reliability are at the core of the Smith 35-125-540 design. It features Smith's exclusive Sure-Seat technology, which incorporates a copper-nickel filter that encases the high-pressure seat. This advanced filtration system effectively blocks debris and contaminants from entering the seating area, ensuring a positive gas-tight seal time after time and significantly reducing repair costs and downtime. The regulator body is constructed from forged brass, paired with a corrosion-resistant nickel-plated bonnet, providing robust protection against the harsh conditions typical of industrial environments.

The internal mechanism utilizes a highly durable reinforced neoprene composite diaphragm that offers exceptional sensitivity and extended service life compared to standard metal diaphragms. Safety is paramount, and this model includes an external self-reseating relief valve that automatically releases excessive pressure in the event of a surge, protecting the regulator and the user. The 2.0-inch gauges are protected by shatter-resistant polycarbonate lenses, ensuring readability and safety even under impact. With a delivery range of 0-125 PSIG and a CGA 540 inlet connection, this regulator is the ideal choice for medium to heavy-duty applications where performance cannot be compromised.
