The Maxitrol RV48L is a high-performance pressure regulator designed specifically for natural gas applications. This professional-grade unit is engineered to maintain consistent and reliable outlet pressure, ensuring optimal operation for connected equipment. The regulator features a 1/2 PSIG inlet pressure rating and delivers a highly adjustable outlet pressure range of 3″ to 6″ Water Column, providing the precise control needed for various gas-powered systems. Built with durability in mind, the RV48L is compatible with standard 3/4″ gas pipes, utilizing a 3/4″ Female Pipe Thread (FPT) on both the inlet and outlet for a secure and leak-free connection.
Proper installation is critical to the safe and effective operation of the Maxitrol RV48L. It is important to note that while this regulator is designed for 3/4″ gas pipes, the physical openings measure 1-1/16″ in diameter, which corresponds to the outside diameter of standard 3/4″ gas piping. Buyers should verify their pipe size and opening dimensions before purchasing to ensure a proper fit. The regulator is designed to operate within a specific temperature range of 32°F to 225°F (0°C to 107°C). To maintain accurate pressure regulation, it is advised to avoid installing the unit in extremely cold environments or in close proximity to heating equipment, as extreme temperature fluctuations can affect the internal spring resistance and overall performance.
