GAS PRESSURE REGULATORS CATALOG - Maxitrol
• Solution: The RV48 (1/2”) has a maximum capacity of 230,000 Bth/h and a maximum individual load of 160,000 Btu/h. The pressure drop at a flow rate of 150,000 Btu/h is 0.4” w.c., well below the available differential of 3” w.c. The RV48 (without “L” fixed orifice) is the correct regulator to use for the application.
