OVERVIEW

Victor 0781-1463 SR 4K-347 Heavy Duty Piston Regulator

When your operation demands high-pressure air control that won't quit, the Victor 0781-1463 SR 4K-347 Regulator is the tool for the job. This heavy-duty regulator is specifically engineered for high-pressure applications where standard equipment falls short. With a massive delivery capability of up to 4500 PSIG, it is the go-to solution for professionals performing pressure vessel testing, dead-end testing, and other critical high-pressure air tasks. The unit connects via a CGA 347 inlet, designed for high-pressure cylinders, and supports a maximum inlet pressure of 5500 PSIG.

The core of the 0781-1463's reliability lies in its piston-style actuation. While diaphragm regulators are excellent for low to medium pressures, they can be vulnerable to rupture or fatigue at the pressures the SR4K handles. The brass piston in this model offers superior strength and longevity, ensuring that the regulator maintains accurate pressure delivery over a long service life. The body and housing cap are machined from solid brass, providing a heavy, durable feel that resists impact and corrosion. Inside, a PCTFE seat within a cartridge assembly ensures a positive shut-off and reliable regulation, minimizing the risk of creep or leakage.

Victor has designed this regulator with the user in mind. The adjustment mechanism features a Delrin cap bushing, which reduces friction and allows for precise, smooth setting of the outlet pressure. The regulator includes a 1/4-inch Swagelok outlet connection, a standard in high-pressure fluid systems, allowing for easy integration with stainless steel tubing and other high-grade components. Additionally, the external adjustable relief valve provides an extra layer of safety, protecting downstream equipment from over-pressurization. For welders and industrial technicians requiring a dedicated high-pressure air regulator, the Victor SR 4K-347 offers unmatched durability and performance.

FAQ

The Victor SR4K-347 can deliver pressures ranging from 300 up to 4500 PSIG.

It features a CGA 347 inlet connection, which is standard for high-pressure air cylinders.

No, this specific model (0781-1463) is designed and cleaned for Air service. Always use a regulator designed specifically for the gas you are using.

Piston regulators are generally more durable and reliable for high-pressure applications (typically above 500 PSI delivery) because they do not have a flexible diaphragm that can burst or fatigue under high stress.

The regulator comes with 2.5-inch brass gauges for easy reading of inlet and delivery pressures.

Yes, it includes a 1/4-inch Swagelok outlet connection with a 1/4-inch stainless tube fitting.

The maximum inlet pressure rating for this regulator is 5500 PSIG.

It is not recommended. The delivery range starts at 300 PSIG. For lower pressures, a different regulator series (like the SR450 or SR250) would be more appropriate.
