CL231 Regulator: Precision Regulation for Commercial Applications
The CL231 regulator excels in medium-sized commercial and industrial settings where precise pressure control is essential. Engineered for exceptional accuracy, this regulator maintains consistent downstream pressure even under variable flow conditions.
Beyond its technical performance, the ROOTS CL231 (previously Itron CL231) offers compelling economic advantages. Users benefit from significantly lower upfront investment costs compared to similar capacity regulators. The streamlined design reduces installation complexity and time, generating immediate labor savings. Over the equipment’s service life, the CL231’s robust construction and simplified maintenance requirements continue to deliver cost efficiencies through decreased service frequency and parts replacement.
For facilities managers and gas system operators seeking performance and value, the CL231 regulator provides the optimal balance between reliable regulation and long-term cost effectiveness.
CL231 Industrial Regulators
The CL231 was designed for systems requiring highly accurate pressure regulation, such as:
- Metering loads (approx. 500 to 7500 CFH) without the need for expensive instrumentation
- As a 1 1/2" or 2" regulator covering the outlet range from 1 PSIG to 20 PSIG without downstream control
- Where very accurate PSI to PSI regulation (+/- 1% outlet pressure absolute) is desired that is obtainable from conventional spring-loaded regulators ahead of a "Fixed Factor Billing" meter or ahead of a "Pressure Compensating Index" meter
- As a reliable and accurate replacement (without downstream control) for conventional regulators requiring downstream control
The two versions available are:
- CL231R - The CL231R is a constant-pressure-loaded regulator with a pilot internal relief valve. The pilot relief valve is not designed for "full capacity" relief, but rather to limit the loading chamber pressure to a safe value in the event of failure.
- CL231N - The CL231N is a constant pressure-loaded regulator that utilizes a pilot with no internal relief (N). This regulator can be used where PSIG to PSIG regulation is required, with no internal relief
