0790-0234RP - Victor G250/G350 Red Replacement Adjustment Knob

Technical Overview of the Victor 0790-0234RP Repair Knob

The Victor 0790-0234RP is a specialized replacement component designed for the maintenance and repair of Victor G250 and G350 series industrial gas regulators. As a critical interface component, this knob attaches to the pressure adjusting screw mechanism, allowing operators to precisely control the delivery pressure of fuel gases. The component is manufactured to exact OEM specifications, ensuring that the thread engagement and mechanical fitment are identical to the original factory-installed part. This ensures that the torque transfer from the operator's hand to the internal spring compression mechanism remains linear and predictable, a vital requirement for stable flame characteristics in oxy-fuel processes.

The knob is molded from a durable, high-impact polymer designed to resist the mechanical stresses and thermal fluctuations common in industrial welding environments. It is finished in industry-standard red, which serves as a mandatory visual indicator for Fuel Gas service (such as Acetylene, Propane, or Propylene), distinguishing it from Oxygen service components (typically green) to prevent dangerous cross-connections or misidentification. The surface of the knob features an ergonomic, fluted design that provides positive traction, facilitating adjustment even when the operator is wearing heavy welding gloves. By replacing a damaged or missing knob with this genuine Victor part, facilities can maintain the operational integrity and safety compliance of their gas regulation equipment without the capital expense of full unit replacement.

Proper maintenance of regulator external components is essential for safe operation. A compromised adjustment knob can lead to difficulty in setting correct pressures, potentially causing unstable flames or flashback conditions. This replacement part allows maintenance personnel to quickly refurbish G-Series regulators, extending the service life of the equipment while adhering to the manufacturer's safety protocols.
