0781-3584 - Victor VTS260A-510 Two-Stage Acetylene Regulator CGA-510

Precision Acetylene Control with Victor VTS260A-510

The Victor 0781-3584 VTS260A-510 Acetylene Regulator is a premium medium-duty solution designed for applications requiring absolute precision and consistency. Part of the renowned VTS 250 series, this two-stage regulator is engineered to deliver a constant outlet pressure ranging from 2 to 15 PSIG, regardless of fluctuations in the inlet pressure. This characteristic is critical in laboratory settings, precise heating applications, and high-quality welding where flame stability directly impacts the work result. By reducing the high cylinder pressure in two distinct steps, the VTS260A-510 isolates the delivery pressure from the decaying tank pressure, ensuring a linear flow profile throughout the life of the cylinder.

Constructed with a die-forged brass body and a heavy-duty spring housing cap, this regulator is built to withstand the rigors of industrial environments while maintaining instrument-grade accuracy. The internal mechanism features a 1.3-inch fabric-reinforced neoprene diaphragm that provides exceptional sensitivity and response to pressure changes. The flow coefficient (Cv) of 0.082 ensures adequate flow for medium-duty tasks without compromising control. Victor has integrated a sintered bronze inlet filter to trap particulates before they can damage the seat, significantly extending the service life of the unit.

Ease of operation is enhanced by the inclusion of a Delrin insert bushing and a stainless steel ball in the adjustment key, reducing friction and allowing for smooth, fine-tuned pressure settings. The regulator is equipped with 2-inch steel gauges—one indicating the inlet supply (up to 400 PSIG for acetylene service) and the other indicating delivery pressure. Safety features include a stem-type seat mechanism that aids in positive sealing and an external self-reseating relief valve. The unit connects via a standard CGA 510 inlet and a 9/16"-18 LH(M) outlet, making it compatible with standard acetylene cylinders and hoses.

Whether used for testing, calibration, or specialized fabrication, the Victor VTS260A-510 offers the reliability and performance professionals demand. Its robust design combined with two-stage precision makes it a superior choice over single-stage alternatives for critical gas control applications.
