Itron CL38 Pressure Regulator

Itron CL38

The CL38 is a constant pressure loaded regulator for use where a closer pounds to pounds regulation is desired than can be obtained from conventional spring loaded regulators. Since, it requires an inlet pressure supply of only ½ PSIG above outlet pressure, this unit can be used where demand type loading will not meet the low pressure differential. The key feature of the CL38, compared to other CL series regulators, is the large 2” valve body which is designed to handle the increased gas flows of the larger orifice sizes

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.
