Smith Equipment 30 Series Medium Duty Hydrogen Methane Regulator CGA 350

Reliable Performance for Welding and Heating

When it comes to fuel gas regulation, the Smith Equipment 30 Series Hydrogen/Methane Regulator delivers the rugged dependability that professional welders and fabricators trust. Known for their association with Miller Electric, Smith regulators are built to withstand the daily abuse of the shop floor while maintaining precise control. This medium-duty, single-stage regulator is specifically configured with a CGA 350 inlet for Hydrogen and Methane cylinders, offering a delivery pressure range of 0-100 PSIG. It is an excellent choice for common gas heating and welding operations where hydrogen is the preferred fuel gas.

Built to Last with Sure Seat™ Technology

Regulator failure is often caused by dirt and debris entering the high-pressure seat. The Smith 30 Series combats this with Sure Seat™ technology, a filtered seat assembly that blocks contaminants before they can cause damage. This innovation extends the service life of the regulator, saving you money on replacements and repairs. The body is forged from brass for strength, while the bonnet features a bright nickel plating that resists corrosion and wear. The large, easy-to-read 2-inch gauges are encased in polished brass and protected by shatter-resistant polycarbonate lenses, ensuring you can always monitor your cylinder and delivery pressures clearly, even in low-light shop conditions.

Precise Control and Safety Features

For applications requiring fine-tuned pressure adjustments, the 30 Series features a neoprene composite diaphragm. This material provides excellent sensitivity, allowing for smooth and accurate pressure settings that hold steady during operation. Safety is also a top priority; the unit includes an external self-reseating relief valve that protects the regulator from high-pressure surges. This valve automatically vents excess pressure and resets, preventing damage to the internal components.
