TECHNICAL BULLETIN 123-TB 04-12 MODEL 123 BACK PRESSURE / RELIEF REG U LA TOR The Model 123 is a relief regulator suitable as a back pressure regulator or bypass valve for controlling inlet pressure between 2 and 350 psig (.14 to 24.2 Barg) (525 psig (36.2 Barg) at 50% build-up). The body has an angle confi guration with a side inlet and a bottom outlet. Sizes are 1/2", 3/4", 1", 1-1/2" and 2" (DN15, 20, 25, 40 and 50). Available options include cryogenic construction, NACE construction and a large selection of trim, body and di a phragm materials. It is the most adaptable back pressure/relief regulator Cashco manufactures. FEATURES Versatile: Controlled Compression Composition Seats: High Capacity: Five body materials & twenty three trim material com bi na tions allow com pati bil i ty with most fl uids. Four composition seat materials are available and all use controlled compres sion with metal to metal back up for long, trouble free life. A large orifi ce and diaphragm provide sensitivity with high capacity. MODEL 123 APPLICATIONS Designed for controlling a wide range of fl uids including air, inert gases, cryogenic gas or liquids, sour gas, chemicals, water, fuel oil and steam. See 1 for more in for ma tion. CAUTION This is not a safety device and must not be sub - sti tut ed for a code ap proved pressure safe ty relief valve or rupture disc.

for expanded air on the downstream side. Use of higher velocities normally generate high noise levels. Metric Conversion Factors: psig/14.5 = Barg; LBS/HR X 0.4536 = KG/Hr. 123-TB 10
