CL34 Commercial & Industrial Pressure Regulator

Brand: Itron

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.
Features
  • Constant loaded pilot design (“fixed-factor” pressure control)
  • Interchangeable brass orifice
  • 78 in² of diaphragm area 
  • Spring-loaded pilot internal relief valve assembly 
  • Field interchangeable pilot adjustment spring 
  • Controlled internal bleed hole eliminates pulsation
  • Wide range of valve body sizes including NPT and flange connections
  • 16 different available assembly positions
Benefits
  • Economical 
  • Light weight 
  • Accurate pressure control for “fixed-factor” measurement applications 
  • No special start-up procedures required 
  • Internal monitor version eliminates the need for external relief valves or separate monitoring devices 
  • No special tools required for outlet pressure adjustment
  • No minimum differential pressure requirement
