70A15 - ESAB 70A15 Diaphragm Plate for R-52 Regulators

Precision Regulator Component

The ESAB 70A15 Diaphragm Plate is a critical internal component designed specifically for the legacy Purox R-50, R-51, and R-52 series of industrial gas regulators. This plate serves as the mechanical interface between the regulator's main control spring and the flexible diaphragm membrane. By evenly distributing the downward force of the spring across the diaphragm surface, it ensures accurate pressure regulation and responsive gas flow control during welding, cutting, and heating operations.

Manufactured to original equipment specifications, this diaphragm plate maintains the structural integrity required for high-pressure gas service. It is engineered to prevent diaphragm distortion and localized wear, which can lead to pressure creep or leaks. The plate is constructed from durable materials designed to withstand the internal forces of the regulator bonnet assembly without bending or warping over time.

When performing a regulator overhaul or repair, replacing worn, corroded, or damaged internal plates with genuine ESAB parts is essential for maintaining safety standards and operational performance. This component is compatible with various gas service configurations found in the R-series line, including oxygen, acetylene, and inert gases. It acts as a direct replacement part, ensuring a perfect fit within the regulator bonnet without the need for modification or adjustment.
