30-15-200 - Smith Series 30 Medium Duty Acetylene Regulator CGA 200

Technical Overview of the Smith Series 30 Acetylene Regulator

The Smith Equipment 30-15-200 is a precision-engineered, single-stage medium duty regulator designed specifically for acetylene gas service using MC (10 cubic foot) cylinders. This unit is a cornerstone of the Series 30 line, renowned for its robust construction and reliability in industrial environments. At the heart of this regulator is Smith's exclusive Sure Seat™ technology. This filtered high-pressure seat assembly is critical for maintaining long-term performance; it actively prevents microscopic contamination and debris from entering the seating area, which is the leading cause of regulator failure and creep. By filtering the gas stream before it reaches the seat, the 30-15-200 significantly reduces maintenance intervals and repair costs.

Structurally, the regulator features a forged brass body paired with a corrosion-resistant, bright nickel-plated bonnet. This combination ensures the device can withstand harsh working environments without succumbing to external corrosion. The internal mechanism utilizes a highly durable neoprene composite diaphragm. Unlike standard rubber or stainless diaphragms, this composite material offers an exceptional balance of sensitivity and durability, allowing for precise adjustment of outlet pressure between 0 and 15 PSIG. This level of control is essential for applications requiring stable low-pressure flows.

Safety and compliance are paramount in the design of the 30-15-200. It includes an external self-reseating relief valve that protects the regulator and downstream equipment from damage due to inadvertent high-pressure surges. The valve automatically resets once the pressure normalizes. The unit is equipped with two 2.0-inch polished brass gauges protected by shatter-resistant polycarbonate lenses, ensuring readability and safety even if impacted. The inlet connection is a standard CGA 200, rated for a maximum inlet pressure of 400 PSIG, making it strictly compatible with MC-style acetylene tanks.
