0761-0107 - Victor Regulator Pressure Adjusting Spring 0761-0107

Technical Overview of the Victor 0761-0107 Adjusting Spring

The Victor 0761-0107 Adjusting Spring is a critical mechanical component designed for use within specific Victor gas pressure regulators. In the context of gas regulation, the adjusting spring serves as the primary interface between the operator's manual input and the internal diaphragm mechanism. When the regulator adjusting screw is turned, it compresses this spring, which in turn exerts a calibrated force upon the diaphragm. This force determines the outlet pressure of the gas delivery system. As such, the mechanical properties of this spring—specifically its spring constant and resistance to fatigue—are vital for maintaining a stable and predictable delivery pressure during operation.

Manufactured by ESAB under the Victor brand, this spring is engineered to meet strict OEM specifications. It is constructed from high-grade spring steel, selected for its ability to maintain elasticity and resist permanent deformation (set) even after repeated cycles of compression and release. In industrial gas applications, where precise pressure control is paramount for both process quality and safety, using non-OEM substitutes can lead to erratic pressure fluctuations or "creep," where delivery pressure rises unintentionally. The 0761-0107 ensures that the force applied to the diaphragm remains linear and consistent relative to the position of the adjusting knob.

This component is typically located within the bonnet assembly of the regulator. Over time, springs can suffer from fatigue or corrosion, particularly in harsh industrial environments. Replacing a worn or damaged spring with the genuine Victor 0761-0107 restores the regulator's ability to finely tune outlet pressure, ensuring the device performs within its rated specifications. It is an essential spare part for maintenance, repair, and operations (MRO) professionals tasked with the upkeep of oxy-fuel cutting, heating, and welding equipment.
