0781-2440 - Victor LC350DR-540 Liquid Cylinder Oxygen Regulator

Victor LC350DR-540 Oxygen Regulator: Precision Control for Liquid Cylinders

The Victor LC350DR-540 Regulator (SKU: 0781-2440) is a specialized gas control device engineered to meet the unique demands of withdrawing gas from liquid cylinders. Unlike standard high-pressure cylinder regulators, the LC350DR series is optimized for the vaporization rates and pressure characteristics found in cryogenic liquid vessels (dewars). This specific model is configured for Oxygen service, featuring a standard CGA 540 inlet connection that ensures compatibility with most industrial oxygen liquid cylinders and supply lines.

With a delivery pressure range of 5 to 125 PSIG, this regulator offers versatile performance for a variety of medium-duty applications. Whether you are supplying oxygen for cutting torches, heating applications, or distribution manifolds, the LC350DR-540 provides the stability required for consistent results. The "DR" designation typically points to its role as a Delivery Regulator, ensuring that the gas pressure downstream remains constant despite fluctuations in the supply pressure or flow demand from the liquid source.

Victor Equipment is renowned for its commitment to quality and durability, and this regulator is no exception. Built with a robust brass body, it is designed to withstand the rigors of industrial environments. The internal mechanism features a sensitive yet durable diaphragm that responds quickly to changes in demand, maintaining a steady outlet pressure. This is particularly important when working with liquid cylinders, where the gas generation rate can vary based on ambient temperature and withdrawal rates. By smoothing out these variations, the Victor 0781-2440 protects downstream equipment and ensures process integrity.

Safety is paramount in oxygen service. The LC350DR-540 is manufactured to strict industry standards, ensuring leak-tight performance and resistance to ignition hazards associated with oxygen-enriched environments. The regulator's design minimizes the risk of pressure creep, providing peace of mind for operators. For facilities utilizing liquid oxygen cylinders for their primary gas supply, this regulator represents an essential link in the delivery chain, combining Victor's heritage of reliability with specific engineering for cryogenic gas applications.
