2117105 - ESAB R-52 Series Heavy Duty Gas Regulator, 0-200 PSI

Technical Overview of the ESAB R-52-200 Regulator

The ESAB R-52-200 is a robust industrial gas regulator designed to meet the rigorous demands of heavy-duty welding, cutting, and heating applications. Engineered within the renowned R-52 series, this device exemplifies precision fluid dynamics and mechanical durability. The core of the regulator features a forged brass body, which provides exceptional resistance to corrosion and mechanical impact, ensuring a long service life even in harsh industrial environments. The internal architecture is designed to minimize pressure drop and maintain a stable delivery pressure, which is critical for process consistency.

This specific model offers a delivery pressure range of 0-200 PSIG. This wide range makes it highly versatile, suitable for high-pressure applications such as heavy heating or running pneumatic tools that require higher static pressures than standard welding operations. The diaphragm mechanism is engineered for sensitivity, allowing for fine adjustments to the outlet pressure. This ensures that the downstream equipment receives a constant flow of gas, regardless of minor fluctuations in the inlet pressure from the cylinder.

Safety and maintenance are paramount in the design of the R-52-200. The unit includes a sintered bronze inlet filter, which acts as a critical barrier against dust, dirt, and other particulates that can compromise the valve seat and lead to regulator creep or failure. Additionally, the regulator is equipped with an internal relief valve designed to vent excess pressure safely in the event of a malfunction, protecting both the operator and the downstream equipment. The gauges are calibrated for accuracy and feature high-contrast faces for immediate visual verification of cylinder and delivery pressures.

Integration into existing gas manifolds or cylinder setups is straightforward, provided the correct CGA connections are utilized. The R-52-200 is compatible with standard industrial fittings, making it a flexible component for maintenance, repair, and operations (MRO) inventories. Its construction adheres to strict industrial standards, ensuring reliability and compliance with safety regulations.
