Product Description
CL231 Regulator
Features + Benefits
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 than 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 equipped 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
