RV20 RV47 RV48 CV47 D.............Integral ball check limiting device permits higher maximum individual load. see Capacities and Pressure Drop page 6 E..............Excessive pressure rated. F..............Factory-set fixednon-adjustable regulator. I..............Left side integral manual valve outlet faces main inlet CV47. L..............Integral vent limiting orifice as the breather hole - with dust cap. M............B.S.P. - PL parallel thread - conforms to ISO 7-1 where pressure tight joints are made on the threads. N.............Internal by-pass orifice to prevent lockup. Main burner only RV20 RV47 RV48 CV47. R.............Right side integral manual valve outlet faces main outlet CV47. SR............Side pressure tap right side 18 NPT RV20 RV47 RV48 CV47I. S..............Side pressure tap left side 18 NPT RV20 RV47 RV48 CV47R. T.............Higher ambient temperature range. V.............Threaded vent connector 516-24 for 18 tubing connection RV20 - with dust cap. Short stack models have an adjustment range of less than 2 w.c. 0.5 kPa these models are advantageous where installation must be made in a limited space. CV47 is best described as a RV47 with an extra regulated outlet. This outlet contains an integral manual valve located on the valve bodys side. Convertible regulators are designed to deliver either of two fixed outlet pressures for natural or LP gases.
