30-50-510 - Smith 30 Series Propane/Propylene Regulator, CGA 510, 0-50 PSIG

Smith 30 Series Medium-Duty LP Gas Regulator

The Smith 30 Series LP Gas Regulator (Model 30-50-510) is a premium medium-duty industrial regulator designed to provide precise control for Propane, Propylene, and Natural Gas applications. Engineered for reliability in demanding environments, this single-stage regulator features a maximum delivery pressure of 50 PSIG and utilizes a standard CGA 510 inlet connection. It is an essential component for professionals in aerospace, construction, heavy equipment manufacturing, and infrastructure who require consistent gas flow for heating and cutting operations.

Exclusive Sure-Seat™ Technology

One of the standout features of the 30 Series is the exclusive Sure-Seat™ filtered high-pressure seat assembly. In typical industrial environments, dust, dirt, and debris can enter the gas stream and damage the regulator seat, leading to leaks and premature failure. Smith's Sure-Seat technology incorporates a copper-nickel filter that traps contaminants before they reach the critical seating area. This innovation significantly extends the lifespan of the regulator, reduces maintenance downtime, and lowers long-term repair costs.

Rugged Construction and Precision

Built to withstand the rigors of daily industrial use, the 30-50-510 features a rugged forged brass body paired with a corrosion-resistant bright nickel-plated bonnet. The internal mechanism is driven by a highly durable neoprene composite diaphragm, which offers superior sensitivity and precise adjustment of outlet pressure compared to standard metal diaphragms. This ensures a stable flame and consistent performance during operation. The regulator is also equipped with 2.0-inch polished brass gauges protected by shatter-resistant polycarbonate lenses, ensuring readability and safety even in tough shop conditions.

Safety and Compliance

Safety is paramount in gas regulation. This model includes an external self-reseating relief valve that protects the regulator from damage due to inadvertent high-pressure surges. If excessive pressure builds up, the valve releases it safely and automatically resets, allowing operations to continue without manual intervention. Color-coded labels further enhance safety by clearly identifying gas service capabilities and technical specifications, minimizing the risk of incorrect setup.
