0730-0063 - Victor 350 Series Regulator Diaphragm and Seat Assembly

Precision Replacement for Heavy-Duty Gas Control

The Victor 0730-0063 Diaphragm Assembly is a critical maintenance component engineered specifically for the Victor 350 Series of heavy-duty industrial regulators. As the heart of the pressure regulation mechanism, the diaphragm is responsible for sensing downstream pressure changes and modulating the valve opening to maintain a consistent flow. Over time, diaphragms can lose elasticity or develop micro-fissures, leading to performance degradation. This genuine OEM replacement ensures that your equipment continues to operate within its specified safety and performance parameters.

This assembly is distinguished by its inclusion of a "Unified Seat." In regulator design, the seat and the diaphragm work in tandem to control gas flow. By integrating the seat assembly with the diaphragm or providing them as a matched set within this part number, Victor simplifies the overhaul process. This design minimizes the margin for error during installation, ensuring that the seating surface aligns perfectly with the nozzle to prevent high-pressure leaks or "creep"—a condition where delivery pressure rises when the torch valves are closed.

Manufactured to Victor's exacting standards, the 0730-0063 utilizes high-grade materials compatible with the gases typically used with 350 Series regulators. Whether used in oxygen, acetylene, or inert gas service (depending on the specific regulator model's original configuration), this diaphragm assembly provides the durability required for harsh industrial environments. Regular inspection and timely replacement of the diaphragm and seat are essential for compliance with safety protocols and for extending the operational lifespan of premium gas equipment.
