CL38 Commercial Pressure Regulator
Brand: ItronThe CL38 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 this regulator 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
- Internal lower diaphragm chamber pressure flow control
- 133 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
- Capacities from 1,500 CFH to 20,000 CFH available
Benefits
- Economical
- Light weight
- Accurate pressure control for “fixedfactor” 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
