SRB Combination Reducing - Relief Regulators serve a dual function. They relieve upstream pressure while at the same time controlling downstream pressure. The controlled pressure downstream is equal to the upstream pressure minus the spring setting. Springs are color-coded in cataloged pressure ranges. Inlet pressures to 25 psig operating; maximum surge to 50 psig without damage. FEATURES   Available in sizes 3/4'' through 3'' NPT. Drip tight shut-off below start to open point Balanced valve design Synthetic reinforced diaphragms - for air, all fuel & inert gases Inlet pressures to 25 psig operating, maximum surge to 50 psig without damage Rugged proven design Standard SRB series operating temperatures to 150°F   CAPACITY TABLE Relief Regulator Catalog Number Pipe Size NPT Capacities in SCFH of Various Specific Gravity Gases @ 14" W.C.
