22349 - ESAB R-6700 Regulator Diaphragm Pressure Plate

Genuine ESAB Replacement for R-6700 Series

The ESAB 22349 Plate Diaphragm is a critical replacement component designed specifically for the maintenance and repair of R-6700 series gas regulators. In the world of industrial gas control, the R-6700 is known for its robust performance in heavy-duty applications, often found in steel mills, scrap yards, and fabrication shops. Over time, the internal components of even the toughest regulators require inspection and replacement to ensure safe operation. This diaphragm plate plays a pivotal role in the mechanical function of the regulator, acting as the interface between the adjusting spring and the flexible diaphragm itself.

When a regulator is in operation, the balance of forces between the adjusting spring and the gas pressure against the diaphragm determines the outlet pressure. The diaphragm plate ensures that the force from the spring is distributed evenly across the diaphragm surface, preventing localized stress that could lead to premature tearing or rupture. It also provides the rigid backing necessary for the diaphragm to move smoothly and responsively to changes in downstream demand. Using a genuine ESAB part like the 22349 ensures that the dimensions, weight, and material properties match the original engineering specifications exactly. Aftermarket or makeshift replacements can alter the spring rate or travel distance, leading to unstable delivery pressure, "creep," or reduced flow capacity.

For maintenance professionals and equipment repair specialists, sourcing OEM parts is the only way to guarantee the integrity of a rebuild. The R-6700 series handles high pressures and high flow rates; therefore, every internal component must be up to the task. This plate is manufactured with precision to fit perfectly within the bonnet assembly, ensuring that the regulator can be reassembled easily and correctly. Whether you are performing a routine overhaul or addressing a specific failure, the ESAB 22349 Plate Diaphragm is the correct choice for restoring your equipment to its optimal working condition.

Proper maintenance of gas equipment is not just about performance; it is a matter of safety. A malfunctioning regulator can lead to dangerous over-pressurization of downstream equipment. By utilizing authentic ESAB replacement parts, you mitigate risks and ensure compliance with safety standards. This part is sold individually and is an essential item to have on hand when performing a complete regulator tear-down and rebuild.
