0730-0055 - Victor 0730-0055 Regulator Diaphragm & Relief Assembly

Restore Precision with the Victor 0730-0055 Diaphragm Assembly

In the realm of industrial gas regulation, the integrity of your equipment is paramount for both safety and operational efficiency. The Victor 0730-0055 Diaphragm/Relief Assembly is a critical replacement component designed to maintain the high performance of Victor's heavy-duty regulators. Specifically engineered for the SR 450, SR 460, and SR 700 series, this assembly ensures that your gas delivery systems operate within their specified pressure parameters, safeguarding downstream equipment and personnel.

Over time, the internal components of a regulator, particularly the diaphragm, are subjected to constant stress, pressure fluctuations, and chemical exposure. A compromised diaphragm can lead to "creep," a dangerous condition where delivery pressure rises steadily when the torch or downstream valve is closed. Replacing a worn diaphragm with this genuine Victor part (0730-0055) effectively resolves these issues. The assembly includes an integrated relief valve, a vital safety feature that vents excess pressure in the event of a regulator failure, preventing catastrophic over-pressurization of the low-pressure chamber.

Constructed from durable, high-grade neoprene and reinforced with precision metal components, this diaphragm assembly offers superior resistance to wear and gas permeation. By choosing genuine OEM parts, you ensure that the replacement matches the exact tension and dimensional specifications of the original unit. This guarantees a perfect seal and accurate response to pressure adjustments. For industrial facilities relying on consistent gas flow for welding, cutting, or heating applications, maintaining your regulators with the Victor 0730-0055 is a proactive step towards reliability and safety compliance.

Key Technical Benefits

The 0730-0055 is not just a rubber disc; it is a calibrated assembly. The relief mechanism is factory-set to function at specific pressures, providing a fail-safe that aftermarket generic parts may not reliably offer. Its robust design is capable of handling the high-flow requirements of heavy-duty regulators, ensuring that your operations continue without interruption due to equipment failure.
