3 If the outlet pressure exceeds this pressure, the Regulator must be removed from serviceand carefully inspected. Damaged or otherwise unsatisfactory parts must be replacedbefore returning the Regulator to maximum outlet pressure that can be safely contained in the diaphragm case is 30 psi, the maximum outlet pressure that can be experienced without damage is 60 psig.(Safely contained means no leakage as well as no bursting.)Orifice1/8"3/16"1/4"5/16"3/8"1 /2"PSIG3002001501007540 THE GAS INDUSTRYM odel 043-CTechnical DataBody Size Outlet: 1"InletOrificePsig1/8"3/16"1/4"5/16"3/8" 1/2".56590140175210270180140200275300400 2100225250375425600317031035050057580052 1540050072582511001034062585011001300 1542585012001550165020550110014501850 3070014002000 4085017502200 50100021502500 60115023002500 8015002400 10018002500 12522002500 Outlet Pressure Set Point 7" @ 50 scfh, and droopSpring: Green except for blue spring in shaded PositionsFBGCDAEEGBACDFS traight Body Connection90 Angle Body ConnectionOther GasesFor use on other compatible gases, flow capacities must be adjusted using the following correction factors.
