0320-0047 - Victor Regulator High Pressure Seat Assembly 0320-0047

Precision Pressure Control Restoration

The Victor 0320-0047 Seat Holder Assembly is a critical internal component designed for the maintenance and repair of Victor's heavy-duty industrial gas regulators. Specifically engineered for the SR 450, SR 460, and SR 700 series, this assembly serves as the primary valve mechanism that modulates high-pressure cylinder gas down to a usable working pressure. In the realm of gas apparatus, the seat assembly is often the most stressed component, subjected to the full force of cylinder pressure and the mechanical action of the adjusting spring and diaphragm.

Over time, the elastomeric seating material within the assembly can degrade due to wear, debris, or oxidation, leading to a phenomenon known as "creep." Creep occurs when the regulator fails to shut off completely when the downstream flow is stopped, causing the delivery pressure to rise slowly on the gauge. This is a significant safety hazard that can damage downstream equipment or lead to diaphragm failure. Installing a genuine Victor 0320-0047 Seat Holder Assembly addresses this issue directly, restoring the regulator's ability to maintain a stable static pressure and ensuring precise flow control during operation.

Manufactured to Victor's exacting tolerances, this assembly features a high-quality brass body and a specially formulated seating material compatible with common industrial gases. Unlike aftermarket alternatives, OEM parts ensure that the flow coefficient (Cv) and mechanical dimensions align perfectly with the regulator's original design specifications. This guarantees that the balance between the high-pressure inlet and the low-pressure chamber is maintained, preserving the regulator's sensitivity and dynamic response. For professional technicians and safety-conscious facilities, utilizing genuine Victor repair parts is the only approved method for extending the service life of heavy-duty gas control equipment.

Technical Specifications & Compatibility

This seat assembly is designed for high-flow, heavy-duty applications where reliability is paramount. It is the standard replacement part for several legacy and current Victor regulator lines used in steel mills, fabrication shops, and oil and gas industries. Proper installation requires a clean environment to prevent the introduction of contaminants that could damage the new seat immediately upon pressurization.
