35-15-510 - Smith Series 30 Two-Stage Acetylene Regulator CGA 510 0-15 PSIG

Precision Engineering for Acetylene Gas Control

The Smith Equipment Series 30 Two-Stage Acetylene Regulator (SKU: 35-15-510) represents a pinnacle in gas regulation technology, designed specifically for industrial environments where precision and safety are paramount. Unlike single-stage counterparts, this two-stage regulator reduces cylinder pressure to working pressure in two distinct steps. The first stage reduces the high-pressure inlet gas to an intermediate pressure, while the second stage reduces it to the final delivery pressure. This mechanical advantage ensures that the outlet pressure remains absolutely constant, even as the cylinder pressure decays during use. For applications requiring unwavering flow rates and pressure stability, the Series 30 is the superior choice.

Advanced Sure-Seat Technology

At the heart of this regulator lies Smith's exclusive Sure-Seat technology. One of the most common causes of regulator failure is the ingress of debris into the high-pressure seat. The Series 30 addresses this with a copper-nickel filter that completely encases the high-pressure seat, effectively blocking contaminants and ensuring a positive gas-tight seal time after time. This filtration system significantly reduces maintenance costs and downtime associated with seat failure.

Robust Construction and Safety

Built to withstand the rigors of industrial use, the 35-15-510 features a forged brass body and a corrosion-resistant nickel-plated bonnet. The diaphragm is constructed from a durable reinforced laminated neoprene composite, offering superior sensitivity and extended service life compared to standard stainless steel diaphragms in this class. Safety is integral to the design, featuring an auto-reset external relief valve that protects the regulator and downstream equipment from inadvertent high-pressure surges. The 2-inch gauges are protected by shatter-resistant polycarbonate lenses, ensuring readability and durability in harsh shop environments.

Specifications and Compatibility

This model is configured with a CGA 510 inlet connection, making it compatible with acetylene cylinders featuring female valve threads. The outlet connection is a standard 9/16"-18 "B" Left-Hand thread, suitable for most industrial oxy-acetylene hoses. With a maximum inlet pressure rating of 400 PSIG and a delivery range of 0-15 PSIG, it is perfectly calibrated for the safe handling of acetylene gas. The regulator is backed by Smith's 3-year limited warranty, underscoring the manufacturer's confidence in its reliability and build quality.
