CL31 Pressure Regulator
Brand: ItronThe CL31 regulator can produce substantial savings for users in lower initial costs, lower installation costs and lower maintenance costs. Optimum valve design limits over boosting or rapid drop-off as the capacity requirement changes, including fast on-off loads.
The CL31 was designed for systems requiring highly accurate pressure regulation such as: utility Fixed Factor metering of relatively small loads (up to 4000scfh)and industrial heating equipment requiring constant high burner pressures (1 PSIG to 20 PSIG).
Please view the Regulator Sizing Application for more information.
