0780-0928 - Victor VTS 700D-580 Extra Heavy Duty Two-Stage Inert Gas Regulator

Technical Overview of the Victor VTS 700D-580 Regulator

The Victor VTS 700D-580 (SKU: 0780-0928) is a premium, extra heavy-duty two-stage regulator designed for high-flow inert gas applications. Engineered for precision and durability, this regulator is part of the VTS 700 series, renowned for its ability to maintain constant delivery pressure over a wide range of decreasing inlet pressures. This characteristic is critical in industrial and laboratory settings where pressure stability directly impacts process integrity and test results.

Constructed with a die-forged brass body, the VTS 700D offers superior strength compared to cast alternatives. The internal mechanism features a stem-type seat which utilizes inlet pressure to aid in sealing, enhancing reliability. A key technical feature is the use of stainless steel diaphragms for both stages (2-inch and 3.25-inch). Stainless steel provides excellent resistance to corrosion and ensures gas purity, making this unit suitable for applications requiring clean inert gases like Argon, Nitrogen, and Helium. The regulator is equipped with a CGA 580 inlet connection, rated for a maximum inlet pressure of 3000 PSIG, and delivers a precise outlet pressure range of 5-125 PSIG.

Operational adjustments are facilitated by a brass adjusting screw with a forged T-handle, incorporating a Delrin insert bushing and a stainless ball in the key for low-friction, smooth torque transmission. The unit also includes an external self-reseating relief valve (on high-pressure models) and a sintered bronze inlet filter to prevent contamination. The 2.5-inch steel gauges provide clear readability of both cylinder and delivery pressures.
