It consists of a relief valve RV-3, the bell jar itself, and the bell jar top coupling C-2 (fig. 11-4). When operating properly, the relief valve RV-3 has a range of 5 to 15 psig. It is leaktight at 5 psi, and is set to relieve at 10 psi. Differential Pressure Gauge, DF-1 The differential pressure gauge is a bellows- operated gauge that operates in the range of 0-100 inches H2O (inches of water). The gauge indicates differential pressure when testing pressure closing and opening valves. Relief Valve, RV-11 The converter section of the test stand is protected from excessive pressure by the RV-11 relief valve. This relief valve is set to relieve pressure in excess of 110 psig. Converter Supply Connection, NIP-6 The converter supply connection NIP-6 connects the converter supply coupling, through the use of a hose, to the test stand. The flow of oxgen shown in figure 11-5 shows   that the 239.551 Figure 11-5.—Test stand schematic. 11-15
