0781-3505 - Victor VTS 250 Series Medium Duty Two-Stage Oxygen Regulator

Precision Control with Victor VTS250C-540 Oxygen Regulator

The Victor 0781-3505 VTS250C-540 Oxygen Medium Duty Two Stage Regulator is engineered for professionals who demand consistency and reliability in their gas delivery systems. As part of the renowned VTS 250 Series, this regulator is designed to provide accurate pressure control for medium-duty applications. The standout feature of this unit is its two-stage regulation mechanism. Unlike single-stage regulators that may allow delivery pressure to rise as the cylinder empties (a phenomenon known as the decaying inlet characteristic), this two-stage model compensates for changes in inlet pressure. This ensures that the outlet pressure remains constant at your set point—between 4 and 80 PSIG—throughout the life of the cylinder, making it ideal for laboratory testing, precise cutting, and general fabrication where stability is critical.

Durability is at the core of the Victor VTS250C-540 design. It features a die-forged brass body and a heavy-duty spring housing cap, providing the structural integrity needed to withstand the rigors of industrial environments. The internal components are equally robust; a stainless steel diaphragm is utilized to offer superior sensitivity and long-lasting service life compared to standard neoprene-only diaphragms. Additionally, the regulator includes a sintered inlet filter made from electroless nickel-plated bronze, which effectively traps particulates and prevents damage to the seat mechanism.

Ease of use is enhanced by the inclusion of a Delrin insert bushing and a stainless ball in the key, which work together to make pressure adjustments smooth and effortless. The 2-inch steel gauges are easy to read, displaying both cylinder contents and delivery pressure clearly. With a maximum inlet pressure rating of 3000 PSIG and a standard CGA 540 connection, this regulator integrates seamlessly into standard oxygen setups. Whether you are managing a welding station or a specialized gas distribution system, the Victor VTS250C-540 delivers the performance and safety features—such as an external self-reseating relief valve—that industry experts trust.
