0780-1199 - Victor L711D-500 Hydrogen & LP Line Regulator, 5-125 PSIG

Victor L711D-500 High Flow Line Regulator for Hydrogen and LP Gas

The Victor 0780-1199 L711D-500 is a premium high-flow line regulator engineered specifically for gas distribution systems requiring consistent pressure and substantial flow rates. Part of the renowned L 700 Series, this extra heavy-duty regulator is designed to manage Hydrogen and LP (Liquefied Petroleum) gases in pipeline applications. Unlike cylinder regulators, the L711D-500 is built to handle the unique demands of bulk gas delivery, ensuring that downstream equipment receives a steady supply of gas without the fluctuations often associated with lower-capacity units.

Constructed with a forged brass body and housing cap, this regulator offers exceptional durability in industrial environments. The internal design features a stem-type seat mechanism and a large 3-1/4 inch diaphragm made from fabric-reinforced neoprene. This combination provides magnificent sensitivity and durability, allowing for precise pressure control even under varying flow conditions. The integration of a Delrin cap bushing ensures smooth adjustments, making it easy for operators to set the delivery pressure within the 5 to 125 PSIG range.

The Victor L711D-500 is not just a regulator; it is a critical component for maintaining the integrity of your gas distribution network. In large-scale manufacturing and fabrication facilities, gas is often supplied via bulk tanks and piped to various points of use. A standard cylinder regulator is ill-equipped for this task due to connection differences and pressure ratings. The L711D-500 bridges this gap, stepping down the intermediate pipeline pressure to a usable working pressure with high precision. The 3.25-inch diaphragm is significantly larger than those found in standard duty regulators, providing a greater surface area for gas pressure to act upon. This results in superior sensitivity, allowing the regulator to react instantly to changes in downstream demand—such as when multiple torches are ignited simultaneously.

Safety and performance are paramount in the design of the L711D-500. With a maximum inlet pressure of 350 PSIG, it is perfectly suited for low-pressure pipeline drops and station drops where high inlet pressures from cylinders are not present. The unit comes equipped with 1/2" NPT female inlet and outlet ports, facilitating seamless integration into standard industrial piping infrastructure. Whether used for automated cutting tables, heat treating, or other bulk gas applications, this Victor regulator delivers the reliability professionals expect. Note: This regulator is designed for pipeline use only and is not suitable for use directly on high-pressure gas cylinders.
