0781-3510 - Victor VTS 250 Series Two-Stage Air Regulator CGA 346

Victor VTS 250 Series: The Standard for Reliability

When your work depends on consistent airflow and precise pressure management, the Victor 0781-3510 VTS250C-346 Two Stage Regulator delivers the performance you need. As a medium-duty regulator designed for air service, it bridges the gap between light-duty commercial units and heavy industrial station regulators. The two-stage design is the standout feature here; unlike single-stage regulators that allow delivery pressure to rise as the cylinder empties, this Victor model compensates automatically, providing a steady flow from start to finish. This is essential for welders and fabricators using air for plasma cutting, gouging, or pneumatic tool operation where consistency is key.

Built Victor Tough

Victor has long been a trusted name in gas equipment, and the 0781-3510 is no exception. The body is machined from die-forged brass, offering superior structural integrity compared to cast alternatives. The adjusting spring is pretested for quality assurance, ensuring that the regulator performs within its specified 4-80 PSIG range right out of the box. A precision-machined nozzle optimizes flow control, while the fabric-reinforced neoprene diaphragm (1.3" to 1.75" depending on the specific internal assembly) provides the sensitivity needed for fine adjustments without sacrificing durability.

User-Friendly Operation

Adjusting your settings is smooth and predictable thanks to the Delrin insert bushing and the stainless steel ball located in the adjustment key. This design reduces friction, making it easy to set your pressure even while wearing work gloves. The large 2-inch steel gauges are easy to read, displaying cylinder pressure up to 4000 PSIG and delivery pressure up to 100 PSIG. The regulator connects via a CGA 346 inlet, the standard for industrial air cylinders, ensuring compatibility with your existing gas supply.

Ideal for Critical Applications

This regulator is specifically recommended for applications where a change in delivery pressure would affect the performance characteristics of the work or test results. With a flow coefficient (Cv) of 0.082, it provides adequate flow for most medium-duty tasks. The unit also features a stem-type seat mechanism that uses inlet pressure to assist in sealing, providing a secure shut-off when not in use. Invest in the Victor VTS250C-346 for a regulator that combines safety, durability, and precision in one compact package.
