The CL34 is appropriate for commercial and industrial applications where very accurate pressure control is required such as fixed-factor metering applications or large boiler and furnace applications. This regulator is a constant pressure loaded regulator for use where closer PSIG to PSIG regulation is desired than can be obtained from conventional spring-loaded regulators. Since the CL34 requires an inlet pressure supply of only 1/2 PSIG above outlet pressure, this unit can be used where demand type loading will not meet the low pressure differential.
