Heavy-Duty Victor SR 4F-347 Air Regulator for Industrial Testing

When your work demands reliable high-pressure air control, the Victor SR 4F-347 High Pressure Piston Regulator stands out as the professional's choice. This heavy-duty regulator is specifically designed to manage the rigorous requirements of pressure vessel testing and dead-end testing. Built with a solid machined brass body and housing cap, it withstands the harsh conditions of industrial environments while delivering consistent performance. The SR 4F-347 is not just tough; it is precise, offering a delivery pressure range of 50 to 750 PSIG to meet a variety of testing needs.

The core of this regulator features a brass piston actuation system, which is significantly more durable than traditional rubber diaphragms when dealing with high inlet pressures. Rated for a maximum inlet of 5500 PSIG, it connects securely to high-pressure air cylinders via a CGA 347 inlet connection. The large 2.5-inch brass gauges provide clear, easy-to-read pressure monitoring, ensuring you always have control over your workflow.

Victor has equipped this model with features that enhance both usability and safety. The Delrin cap bushing ensures that adjusting the pressure is smooth and effortless, preventing the jerky adjustments common in lesser regulators. A sintered bronze inlet filter protects the internal components from particulate damage, extending the life of the unit. Additionally, the 1/4" Swagelok outlet connection provides a secure, industry-standard interface for your hoses or tubing. Whether you are testing pipelines or pressurizing vessels, the Victor SR 4F-347 delivers the safety, power, and reliability you expect from a top-tier brand.
